| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). Higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover is not available.

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invested $10,000 in the applicable class of the Fund for the time periods indicated and then redeemed all of your shares at the end of those periods. The example also assumes that your investment had a 5% return each year and that operating expenses (as a percentage of net assets) of the Fund remained the same. This example reflects contractual fee waivers and reimbursements through January 31, 2026. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

| Strategy [Heading] | rr_StrategyHeading | Principal Strategies | ||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund invests primarily in the equity securities of foreign companies. Under normal market conditions, we will invest the Fund’s net assets primarily in the equity securities, typically common stock, of foreign companies of all market capitalizations, although we expect a significant portion (greater than 5%) of the Fund’s total assets to be invested in companies with market capitalizations of over $5 billion at the time of purchase. The Advisor considers greater than 5% to be a significant portion. Under normal market conditions, the Fund will invest in securities issued by companies domiciled in at least five of the countries included in the MSCI ACWI ex USA Index, which captures large and mid cap representation across developed market countries (excluding the U.S.) and emerging markets countries. The MSCI ACWI ex USA Index includes companies domiciled in countries around the world, including companies in the Asia region, Europe and the U.K. The Fund may invest a significant portion of its total assets (5% to 50% under normal market conditions) at the time of purchase in securities issued by companies domiciled in emerging and frontier markets, which are those countries currently included in the Morgan Stanley Capital International (MSCI) EFM (Emerging + Frontier Markets) Index. These companies typically are located in the Asia-Pacific region, Eastern Europe, the Middle East, Central and South America, and Africa. In seeking to achieve the Fund’s investment objectives, the Fund invests in securities that we believe are priced below their intrinsic long-term value based on our valuation analysis. Our valuation analysis is intended to establish a range for fair valuation or intrinsic company value, with a particular emphasis on company fundamentals. The intrinsic valuation analysis may include: • Calculating and reviewing standard ratios, such as price-to-sales, price-to-book, price-to-earnings, and price/earnings-to-growth. • Discounted cash flow models with sensitivity analysis for changes to revenue growth rates, operating margins, outstanding share counts, earnings multiples, and tangible book value. The Fund typically seeks to sell a security when the issuing company becomes overvalued relative to our analysis of its intrinsic long-term value. The Fund may invest a significant portion of its assets (greater than 5%) in a particular region or market, including Asia and Europe. The Fund may invest a significant portion of its assets (greater than 5%) in a few sectors, including communication services, consumer discretionary, consumer staples, energy, health care, financials, industrials, information technology, materials, real estate, and utilities. The Fund is classified as non-diversified, which means it may invest a larger percentage of its assets in the securities of a small number of issuers than a diversified fund.

| Risk [Text Block] | rr_RiskTextBlock | Non-Diversification Risk. The Fund can invest a larger portion of its assets in the stocks of a limited number of companies than a diversified fund, which means it may have more exposure to the price movements of a single security or small group of securities than funds that diversify their investments among many companies.

| Wasatch International Value Fund | Risk Not Insured Depository Institution [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. | ||||
| Wasatch International Value Fund | Market Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Market Risk. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to, among other things, market movements over the short-term or over longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility.
|
||||
| Wasatch International Value Fund | Current Market and Economic Conditions Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Current Market and Economic Conditions Risk. Current market and economic conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market and economic conditions or events. Actions taken by the Federal Reserve or foreign central banks may at times result in unusually high market volatility, may negatively impact companies, including banks and financial services companies, and negatively impact Fund performance. U.S. regulators have also proposed from time to time changes to market and issuer regulations which may impact the Fund, and any regulatory changes adopted could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact on the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, in February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe and the United States. The hostilities and sanctions resulting from those hostilities may continue to have a significant impact on certain Fund investments as well as performance and liquidity. Similarly, in October 2023, Hamas launched an attack on Israel, which touched off a strong military response from Israel that closed borders and airspace, damaged infrastructure and resulted in significant civilian and military casualties in Israel and the Gaza Strip. The conflict has reignited regional tensions that threaten to involve other countries and factions. The continuing conflict and its escalation could have a severe adverse effect on the regional economy, currency and companies. These events may negatively impact other regional and global economic markets of the world (including Europe and the United States), companies in such countries and various sectors, industries and markets for securities and commodities globally, such as oil and natural gas. Accordingly, the hostilities and sanctions resulting from these hostilities may have a negative effect on certain Fund investments, including investments extending beyond any direct or indirect exposure the Fund may have to issuers of such countries or those of adjoining geographic regions. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. The COVID-19 global pandemic or any future public health crisis and ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. While vaccines have been developed, there is no guarantee that vaccines will be effective against emerging future variants of the disease or new diseases. As the COVID-19 pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets. Further, the interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market.
|

| Wasatch International Value Fund | Government and Regulatory Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Government and Regulatory Risk. The risk that governments or regulatory authorities may take actions that could adversely affect markets in which the Fund invests and in the economy, more generally. Government and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund and to the companies in which the Fund invests. Such legislation or regulation could restrict the ability of the Fund to fully implement its investment strategies, either generally or with respect to certain securities, industries or countries and could limit or preclude the Fund’s ability to achieve its investment objective.

| Wasatch International Value Fund | Stock Market Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Stock Market Risk. The Fund’s investments may decline in value due to movements in the overall stock market.
|
||||
| Wasatch International Value Fund | Stock Selection Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Stock Selection Risk. The Fund is actively managed, and its performance therefore will reflect, in part, the ability of the portfolio manager(s) to select investments and to make investment decisions that are suited to achieving the Fund’s investment objective. The Advisor does not actively track the composition or weightings of market indexes (including the Fund’s benchmark index) or of the broader markets generally. As a result, the Fund could underperform its benchmark index and/or other funds with a similar investment objective and/or strategy or it may lose value even when the overall stock market is not in general decline.
|
||||
| Wasatch International Value Fund | Equity Securities Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Equity Securities Risk. Equity securities represent ownership in a company. They may be traded (bought or sold) on a securities exchange or stock market. Stock markets are volatile. The price of equity securities will fluctuate and can decline and reduce the value of a portfolio invested in equity securities. The value of equity securities purchased by the Fund could decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. The value of equity securities may also decline due to factors that affect a particular industry or industries such as labor shortages, an increase in production costs and changes in competitive conditions within an industry. In addition, the value of equity securities may decline due to, among other things, general market conditions not specifically related to a company or industry such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, changes in government regulations, the political situation, or generally adverse investor sentiment. Certain equity securities may be less liquid, meaning that they may be difficult to sell at a time or price that is desirable, than other types of securities, or they may be illiquid. Some securities exchanges or stock markets may also be less liquid or illiquid due to low trading volume. In addition, equity securities include common stock. Common stock holds the lowest priority in the capital structure of a company and therefore takes the largest share of the company’s risk and its accompanying volatility. The rights of common stockholders generally are subordinate to all other claims on a company’s assets, including preferred stockholders and debt holders with respect to the payment of dividends and upon the liquidation or bankruptcy of the issuing company. The common stock of a company that experiences financial distress may lose significant value or become worthless, and therefore the Fund could lose money if a company in which it invests becomes financially distressed.
|
||||
| Wasatch International Value Fund | Liquidity Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. In addition, the trading market for a particular security or type of security in which the Fund invests may be significantly less liquid than developed or even emerging markets, and there may be little or no trading volume for a period of time for a particular security. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities quickly at a desired price when necessary to meet the Fund’s liquidity needs or in response to a specific economic event. It may be difficult at times to sell such securities at any price, which could impact not only the daily net asset value (NAV) of the Fund, but also the composition of the portfolio if other securities must be sold to meet the Fund’s liquidity needs. Additionally, market quotations for such securities may be volatile and thus affect the daily NAV of the Fund.
|
||||
| Wasatch International Value Fund | Foreign Securities Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Securities Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investments in U.S. securities. Securities issued by companies incorporated outside the United States but whose securities are principally traded in the United States are still subject to many of the foreign securities risks such as economic and political risks. Differences in the economic and political environment, the amount of available public information, the amount of taxation, limitations on the use or transfer of Fund assets, the degree of market regulation, settlement practices, the potential for permanent or temporary termination of trading, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates, can have a significant effect on the value of a foreign security. More specifically, changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities and gains and losses realized on the sale of such securities. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. The Fund may be invested in the local currency of a foreign country in connection with executing foreign securities transactions. When the Fund executes the securities transactions, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. While the Fund is permitted to hedge currency risks, the Advisor does not anticipate doing so at this time. Additionally, certain countries may restrict foreign investment in their securities and may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such capital controls can also have a significant effect on the value of the Fund’s holdings.

| Wasatch International Value Fund | Emerging Markets Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Emerging Markets Risk. In addition to the risks of investing in foreign securities in general, the risks of investing in the securities of companies domiciled in emerging market countries include increased political or social instability, economies based on only a few industries, unstable currencies, runaway inflation, as well as highly volatile, substantially smaller and less liquid securities markets, unpredictable shifts in policies relating to foreign investments, lack of protection for investors against parties that fail to complete transactions, lack of or limited government oversight over securities exchanges and brokers, and the potential for government seizure of assets or nationalization of companies or other government interference in which case the Fund could lose all or a significant portion of its investment in a country.

||||
| Wasatch International Value Fund | Frontier Markets Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Frontier Markets Risk. In addition to the risks of investing in foreign securities in developed and emerging markets, frontier market securities involve unique risks, such as exposure to economies less diverse and mature than those of the U.S. or more established foreign markets. Given the generally smaller size and less developed capital markets than those of emerging markets or other more developed foreign markets, the risks of investing in emerging markets are magnified for frontier markets. Economic or political instability may cause larger price changes in frontier market securities than in securities of issuers based in more developed foreign countries, including securities of issuers in larger emerging markets. Frontier markets generally receive less investor attention than developed markets or larger emerging markets. These risks can result in the potential for extreme stock price volatility and illiquidity.

| Wasatch International Value Fund | Asia Region Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Asia Region Risk. The value of the Fund’s assets may be adversely affected by, among other things, political, economic, social and religious instability, inadequate investor protection, accounting standards and practices, changes in laws or regulations of countries within the Asia region, relations with other nations, natural disasters, corruption, civil unrest, and military activity. Countries in the Asia region, particularly China, Japan and South Korea, may be adversely affected by disputes with many of their neighbors and historically strained relations with Japan could adversely impact economies in the region. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as the rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, and sensitivity to changes in global trade. Certain Asian countries are highly dependent upon and may be affected by developments in the United States, Europe and other Asian economies. Asian economies and companies could be affected if global economic conditions deteriorate as a result of political instability and uncertainty. In addition, international trade could be affected by politically motivated actions in the U.S. and Europe, and by increased tensions with other nations.
|
||||
| Wasatch International Value Fund | Developed Markets Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Developed Markets Risk. The Fund’s investment in a developed country issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. In addition, developed countries may be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

| Wasatch International Value Fund | Europe and United Kingdom Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Europe and United Kingdom Risk. The value of the Fund’s assets may be adversely affected by, among other things, the social, political, regulatory, economic and other events or conditions affecting Europe and the United Kingdom (“U.K.”). The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an impact on other European countries. Many countries in Europe are member states of the European Union (“EU”) and will be significantly affected by the fiscal and monetary controls of the EU. Changes in regulations on trade, decreasing imports or exports, changes in the exchange rate of the euro and recessions or defaults or threats of defaults among European countries may have a significant adverse effect on the economies of other European countries, including those outside the EU. The European financial markets have experienced significant volatility, and several European countries have been adversely affected by unemployment, budget deficits and economic downturns. Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. Successionist movements, as well as governmental or other response to such movements, may also create instability and uncertainty in the region. Efforts by the member countries of the EU to continue to unify their economic and monetary policies also may increase the potential for similarities in movements of European markets and reduce the potential investment benefits of diversification within the region. Further, while many countries in western Europe are considered to have developed markets, many eastern European countries are less developed, and investments in eastern European countries, even if denominated in euros, may involve special risks associated with investments in emerging markets. As the economies of countries in Europe are in different stages of development, the policies adopted by the EU may not address the needs of all European member countries. In addition, one or more countries may abandon the euro and/or withdraw from the EU creating continuing uncertainty in the currency and financial markets generally. In this regard, on January 31, 2020, the U.K. formally withdrew from the EU (commonly referred to as “Brexit”). Following a transition period, the U.K. and EU entered a trade agreement which principally related to goods rather than services, including financial services. Further discussions are to be held between the U.K. and EU in relation to matters not covered by the trade agreement. While new trade deals may boost economic growth, such growth may not be able to offset the increased costs of trade with the EU resulting from the United Kingdom’s loss of its membership in the EU single market. There is significant market uncertainty regarding Brexit’s ramifications. The range and potential implications of possible political, regulatory, economic and market outcomes for the U.K., EU and elsewhere cannot be fully known. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets. The uncertainty of Brexit also could have a significant impact on the business and financial results of companies in the U.K. and European countries and certain sectors within such countries. The United States and European countries are substantial trading partners of the U.K. As a result, the economy of the U.K. may be impacted by changes to the economic health of the European countries and the United States. The precise impact on the economy of the U.K. as a result of its departure from the EU depends to a large degree on its ability to conclude favorable trade deals with the EU and other countries, including the United States, China, India and Japan. Any of these effects of Brexit could adversely affect the European and U.K. companies in which the Fund may invest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses. The occurrence of terrorist incidents throughout Europe also could impact financial markets. In addition, Russian launched its invasion of Ukraine in February 2022 and the extent and duration of the military action, resulting sanctions and resulting future market disruptions in the region are impossible to predict, but could have a significant and severe adverse effect on the region, the economies and markets for certain securities and commodities and sectors.

| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Value Investing Risk. A value investing strategy attempts to identify strong companies with stocks selling at a discount from their perceived true worth. Value stocks include securities of companies that may have experienced, for example, adverse business, industry or other developments or may be subject to special risks that have caused the securities to be out of favor and potentially undervalued. Value investing is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued may actually be appropriately priced.

| Wasatch International Value Fund | Small and Mid Cap Company Stock Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Small- and Mid-Cap Company Stock Risk. Small- and mid-cap company stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of small- and mid-cap companies may therefore be more volatile and the ability to sell these stocks at a desirable time or price may be more limited.

| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Large Company Stock Risk. The Fund may invest in the stocks of large companies. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Many larger companies also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Sector and Industry Weightings Risk. To the extent the Fund emphasizes, from time to time, investments in a particular sector, the Fund will be subject to a greater degree to the risks particular to that sector, including the sectors described below. Market conditions, interest rates, and economic, political, regulatory, or financial developments could significantly affect all the securities in a single sector. If the Fund invests in a few sectors, it may have increased exposure to the price movements of securities in those sectors. The Fund may also from time to time make significant investments in an industry or industries within a particular sector. The industries that constitute a sector may all react in the same way to economic, political or regulatory events. Adverse conditions in such industry or industries could have a correspondingly adverse effect on the financial condition of issuers. These conditions may cause the value of the Fund’s shares to fluctuate more than the values of shares of funds that invest in a greater variety of investments.

| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Communication Services Sector Risk. The communication services sector includes diversified telecommunication services companies, wireless telecommunication services companies, and media and entertainment companies. The communication services sector is subject to government regulation and can be significantly affected by intense competition and technology changes, which may make the products and services of certain companies obsolete. Wireless telecommunication services companies can be significantly affected by failure to obtain, or delays in obtaining, financing or regulatory approval, intense competition, product incompatibility, changing consumer preferences, rapid obsolescence, significant capital expenditures, and heavy debt burdens. Media and entertainment companies can be significantly affected by technological advances, government regulation, and changing consumer preferences.

| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Consumer Discretionary Sector Risk. The consumer discretionary sector includes companies in industries such as consumer services, household durables, leisure products, textiles, apparel and luxury goods, hotels, restaurants, retailing, and automobiles. Companies in the consumer discretionary sector may be significantly impacted by the performance of the overall domestic and global economy and by interest rates. The consumer discretionary sector relies heavily on disposable household income and spending. Companies in this sector may be subject to severe competition, which may have an adverse impact on their respective profitability. The retail industry can be significantly affected by changes in demographics, and consumer tastes and shopping habits, which can also affect the demand for, and success of, consumer products and services in the marketplace. The automotive industry is highly cyclical and can be significantly affected by labor relations and fluctuating component prices.

| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Consumer Staples Sector Risk. The consumer staples sector includes companies in the consumer staples distribution and retail, food, beverage and tobacco, and household and personal products industry groups. Companies in the consumer staples sector may be affected by demographics and product trends, competitive pricing, food fads, marketing campaigns, environmental factors, changes in consumer demands, the performance of the overall domestic and global economy, interest rates, consumer confidence and spending, and changes in commodity prices. Consumer staples companies may be subject to government regulations that may affect the permissibility of using various food additives and production methods. Tobacco companies may be adversely affected by regulation, legislation and/or litigation.

| Wasatch International Value Fund | Energy Sector Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Energy Sector Risk. The energy sector includes companies in the energy equipment and services, and oil, gas and consumable fuels industries. The value of companies in these industries is particularly vulnerable to developments in the energy sector, which may include swift fluctuations in the price and supply of energy fuels caused by events relating to international politics, energy conservation initiatives, the success of exploration projects, the supply of, and demand for, specific energy-related products or services, and tax and other governmental regulatory policies. Oil and gas companies develop and produce crude oil and natural gas and provide related resources such as production- and distribution-related services. Stock prices for oil and gas companies in particular are affected by supply and demand both for companies’ specific products or services and for energy products in general. The performance of these companies will likewise be affected by the price of oil and gas, exploration and production spending, government regulation, world events and economic conditions. Weak demand for energy companies’ products or services or for energy products and services in general, as well as negative developments in these other areas, would adversely impact the energy stocks in which the Fund invests and the Fund’s performance. Oil and gas exploration and production companies can be significantly affected by natural and man-made disasters as well as changes in currency exchange rates, interest rates, government regulation, world events and economic conditions, and the companies may be at risk for environmental damage claims.

| Risk [Text Block] | rr_RiskTextBlock | Financials Sector Risk. The financials sector includes companies in the banks, financial services, and insurance industry groups. Companies in the financials sector are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. Banking companies, including thrifts and mortgage finance and consumer finance companies, may be affected by extensive government regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change. Credit losses resulting from financial difficulties of borrowers can negatively affect banking companies. Banking companies may also be subject to severe price competition. Competition is high among banking companies and failure to maintain or increase market share may result in lost market value. Capital markets, a sub-industry of financial services, may be affected by extensive government regulation as well as economic and other financial events that could cause fluctuations in the stock market, impacting the overall value of investments. The insurance industry may be affected by extensive government regulation and can be significantly affected by interest rates, general economic conditions, and price and marketing competition. Different segments of the insurance industry can be significantly affected by natural disasters, mortality and morbidity rates, and environmental clean-up.

| Risk [Text Block] | rr_RiskTextBlock | Health Care Sector Risk. The health care sector includes companies in the health care equipment and services, and pharmaceuticals, biotechnology and life sciences industry groups. Health care companies are strongly affected by worldwide scientific or technological developments. Their products may rapidly become obsolete. Many health care companies are also subject to significant government regulation and may be affected by changes in government policies. Companies in the pharmaceuticals, biotechnology and life sciences industry group in particular are heavily dependent on patent protection, and the expiration of patents may adversely affect the profitability of such companies. These companies are also subject to extensive litigation based on product liability and other similar claims. Many new products are subject to government approval and the process of obtaining government approval can be long and costly, and even approved products are susceptible to obsolescence. These companies are also subject to competitive forces that may make it difficult to increase prices, or that may lead to price reductions.

| Risk [Text Block] | rr_RiskTextBlock | Information Technology Sector Risk. The information technology sector includes companies in the software and services, technology hardware and equipment, and semiconductors and semiconductor equipment industry groups. Companies in the information technology sector are subject to rapid obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, and general economic conditions. Stocks of companies in the information technology sector, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technological developments, fixed rate pricing, and the ability to retain skilled employees can significantly affect the industries in the information technology sector.

| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Materials Sector Risk. The materials sector includes companies in the chemicals, construction materials, containers and packaging, metals and mining, and paper and forest products industries. Changes in world events, political, environmental and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in currency exchange rates, imposition of import and export controls, increased competition, and labor relations may adversely affect companies engaged in the production and distribution of materials. Other risks may include liabilities for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control. Companies in the chemicals industry may be subject to risks associated with the production, handling and disposal of hazardous components.

| Wasatch International Value Fund | Utilities Sector Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Utilities Sector Risk. The utilities sector includes electric utilities, gas utilities, water utilities, multi-utilities (electric, gas and water), and independent power and renewable electricity producers. Companies in the utilities sector are affected by supply and demand, consumer incentives, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. The value of regulated utility company stocks may have an inverse relationship to the movement of interest rates. Also, certain utility companies have experienced full or partial deregulation in recent years, which may permit them to diversify outside of their original geographic regions and their traditional lines of business. Conversely, companies that remain heavily regulated may be at a competitive disadvantage, making them less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company’s equipment unusable and may have an adverse impact on profitability. Utility companies are subject to the high cost of borrowing to finance capital construction during inflationary periods, restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations, and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation, and the effects of regulatory changes.

| Wasatch International Value Fund | Operational and Cybersecurity Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | Operational and Cybersecurity Risk. Cybersecurity breaches may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of the Fund’s portfolio companies may negatively impact performance. Operational risk may arise from human error, errors by third parties, communication errors, or technology failures, among other causes. The Fund also relies on a range of services from third-parties, including custody. Any delay or failure in the services provided to the Fund may negatively affect the Fund and its ability to meet its investment objective. Although the Fund and the Fund’s investment adviser seek to reduce operational risks through controls and/or procedures, it is not possible to identify and address all such risks and there is no way to completely protect against or mitigate such risks.

| Wasatch International Value Fund | New Fund Risk [Member] | ||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||
| Risk [Text Block] | rr_RiskTextBlock | New Fund Risk. Because a new fund begins operations with few assets, operating expenses for a new fund are relatively high until the fund begins to manage sufficient assets to achieve operating efficiencies. While the Advisor has contractually agreed to reimburse Fund expenses over a certain level for a period of time to keep shareholder expenses at a certain specific level, there is a risk that the expense limitation agreement is not continued and the expenses of the Fund increase significantly until the Fund reaches scale. There is also the risk that the Fund never reaches scale, that the investment strategies do not work as expected and that the Fund fails to achieve its stated investment objective.
