| Expense [Heading] | rr_ExpenseHeading | Fees and Expenses | |||||||||||||
| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and any extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other registered investment companies advised by BFA, or its affiliates, through February 28, 2029. The contractual waiver may be terminated prior to February 28, 2029 only upon written agreement of the Trust and BFA. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate 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 the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 453% of the average value of its portfolio. | |||||||||||||

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund seeks to track the Bloomberg U.S. Fixed Income Balanced Risk Index (the “Underlying Index”), which measures the performance of the corporate and mortgage portion of the Bloomberg U.S. Universal Index (the “Parent Index”) while targeting an equal allocation between interest rate and credit spread risk. As of October 31, 2024, approximately 84% of the Underlying Index consisted of issuers organized or located in the United States, and there were 7,817 issues in the Underlying Index from issuers in over 16 countries or regions. The Underlying Index may include large-, mid- or small-capitalization companies. As of October 31, 2024, a significant portion of the Underlying Index is invested in securities of companies in the financials industry or sector and mortgage-backed securities (“MBS”) and investment-grade corporate bonds. The components of the Underlying Index are likely to change over time. Securities may be registered or privately placed. All securities in the Underlying Index are U.S. dollar-denominated. The Underlying Index uses a rules-based approach to calculate an equal volatility-weighted allocation to each of five segments of the Parent Index: (1) investment-grade corporate bonds 1-5 year; (2) investment-grade corporate bonds 5-10 year; (3) high yield corporate bonds rated BB or higher; (4) high yield corporate bonds rated below BB; and (5) U.S. agency MBS. Segments with lower credit spread volatility receive a higher weighting in the Underlying Index, and segments with higher credit spread volatility receive a lower weighting in the Underlying Index, with the result that the contribution of each segment to overall credit spread volatility is approximately equal. Credit spread volatility aims to capture the volatility of the return attributable to the credit quality of the security. Credit spread volatility for investment-grade corporate securities and MBS components is measured differently than for the Fund’s high yield securities. To increase overall yield and credit spread exposure, the Underlying Index incorporates a leverage factor of up to 25% that redeploys MBS exposure, via cash pending settlement from to-be-announced mortgage transactions (“TBAs”), toward other index constituent securities. The Underlying Index further adjusts interest rate risk so that it equals credit spread risk, by adding either long positions in U.S. Treasury bonds or short positions in U.S. Treasury futures. The Underlying Index is rebalanced monthly. BFA uses an indexing approach to try to achieve the Fund’s investment objective. The Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued. Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies. BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index. The Fund will invest at least 80% of its assets in the component securities of the Underlying Index and TBA transactions that have economic characteristics that are substantially identical to the economic characteristics of the component securities of the Underlying Index, and the Fund will invest at least 90% of its assets in fixed income securities of the types included in the Underlying Index that BFA believes will help the Fund track the Underlying Index. The Fund will invest no more than 10% of its assets in futures, options and swaps contracts that BFA believes will help the Fund track the Underlying Index as well as in fixed income securities other than the types included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a TBA position will be treated as part of that position for purposes of calculating investments in the component securities of the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received). The Underlying Index is sponsored by Bloomberg Index Services Limited (the “Index Provider” or “Bloomberg”), which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

| Bar Chart and Performance Table [Heading] | rr_BarChartAndPerformanceTableHeading | Performance Information | |||||||||||||
| Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The Fund is continuing the operations of a series of iShares U.S. ETF Trust (the “Predecessor Fund”). Before the Fund commenced operations, all of the assets and liabilities of the Predecessor Fund were transferred to the Fund in a reorganization (the “Reorganization”), which was tax-free for U.S. federal income tax purposes. The Reorganization occurred on February 5, 2018. As a result of the Reorganization, the Fund assumed the performance and accounting history of the Predecessor Fund, which did not seek to track the investment results of an index but was managed by BFA using an investment strategy substantially similar to the methodology of the Underlying Index. The performance information below is based on the performance of the Predecessor Fund for periods prior to the date of the Reorganization. The performance information below illustrates how the Fund’s performance has varied over different periods and provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table compares the Fund’s performance to that of an appropriate broad-based securities market index and the Underlying Index. Fund returns assume the reinvestment of any dividends and distributions. The Fund’s returns reflect the impact of any agreements to waive or reimburse expenses, which would reduce performance if not in effect. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information, including the Fund’s current NAV, may be obtained by visiting www.iShares.com or by calling 1-800-iShares (1-800-474-2737) (toll free).

| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Interest Rate Risk. Interest rate risk refers to the risk of fluctuations in the value of a fixed-income security due to changes in the general level of interest rates. Interest rate changes can be sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. An increase in interest rates generally will cause the value of fixed-income securities to decline. Securities with longer maturities generally are more sensitive to interest rate changes and subject to greater fluctuations in value. Changes in interest rates may have unpredictable effects on fixed-income markets and result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders.

An “Authorized Participant” is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows the Authorized Participant to place orders for the purchase and redemption of creation units (“Creation Units”). Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. The Fund’s use of derivatives (e.g., futures, forwards, swaps, options) may be riskier than other types of investments and may not have the intended effect on the Fund’s performance. Derivatives can be sensitive to changes in economic and market conditions, and they may increase the Fund’s volatility. The Fund also may experience reduced returns as a result of transaction costs and losses on derivatives positions. There is the risk of imperfect correlation between the value of a derivative and that of the asset underlying the derivative. Derivatives may create investment leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives are subject to the risk of mispricing or improper valuation, particularly if there is not a liquid secondary market for the instrument. Certain derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives also exposes the Fund to additional operational and legal risks.

| Risk [Text Block] | rr_RiskTextBlock | Hedging Risk. The Fund seeks to mitigate the potential impact of interest rates on the performance of bonds by entering into short positions in U.S. Treasury futures or similar positions through transactions in interest rate swaps. The Fund’s short positions in U.S. Treasury futures and interest rate swaps are not intended to mitigate credit spread risk or other factors influencing the price of bonds, which may have a greater impact than interest rates. There is no guarantee that the Fund’s short positions will completely eliminate the interest rate risk of the long positions in bonds. In addition, when interest rates fall, long–only bond investments will perform better than the Fund’s investments. In certain falling interest rate environments, the Fund’s hedging strategy could result in disproportionately larger losses in the short U.S. Treasury futures and interest rate swaps positions as compared to gains in the long bond positions attributable to interest rate changes. There is no guarantee the Fund will have positive returns, even in environments of sharply rising Treasury interest rates in which the Fund’s short positions might be expected to mitigate the effects of such rises. The Fund will incur expenses when entering into short positions.

| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | High Portfolio Turnover Risk. High portfolio turnover is considered by the Fund to mean turnover of greater than 100% annually. Portfolio turnover (i.e., the sale of securities or other assets and reinvestment in other securities or assets) generally involves transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other costs. In addition, the sale of securities by the Fund may result in the realization of taxable capital gains, including short-term capital gains. Higher portfolio turnover may cause the Fund to incur additional transaction costs, which have the effect of reducing the Fund’s investment return, and may result in different tax consequences for shareholders compared to a fund with lower portfolio turnover.

An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. To the extent the Fund holds illiquid investments, the illiquid investments may reduce its returns because the Fund may be unable to transact at advantageous times or prices. In addition, if the Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, it will need to sell liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for Fund shares may be impacted by the liquidity in the market for the underlying securities or other assets held by the Fund, which could lead to Fund shares trading at a premium or discount to the Fund’s NAV.

Certain shareholders of the Fund, including an Authorized Participant, a third-party investor, the Fund’s adviser, an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may hold their investment in the Fund for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.

If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

| Risk [Text Block] | rr_RiskTextBlock | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

| Risk [Text Block] | rr_RiskTextBlock | Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.

| Risk [Text Block] | rr_RiskTextBlock | Privately Issued Securities Risk. Privately issued securities are securities that have not been registered under the Securities Act of 1933, as amended (the “1933 Act”). Such securities typically are subject to legal restrictions on resale and generally are not traded in established public markets. As a result, privately issued securities may be deemed to be illiquid investments, may be more difficult to value than publicly traded securities, may be subject to wide fluctuations in value and may have higher transaction costs. There can be no assurance that a trading market will exist at any time for any particular privately issued security. Difficulty in selling such securities at a desirable time or price may result in a loss to the Fund.

| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy. The Underlying Index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies, consistent with its objective to track the performance of the Underlying Index. Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and investors may have limited legal remedies. The Fund does not select investments based on investor protection considerations.

| Risk [Text Block] | rr_RiskTextBlock | Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. A Fund that tracks an index with exposure to non-U.S. issuers may experience higher tracking error than ETFs that do not track such indexes. A Fund that tracks an index where high yield securities are an investment focus may experience higher tracking error than ETFs that do not track such indexes. Because the fundamental policies of the Fund do not provide for the Fund to concentrate holdings in accordance with the concentrations included in the Underlying Index, the Fund may experience higher tracking error than other index ETFs.

| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | U.S. Agency Mortgage-Backed Securities Risk. The Fund invests in MBS issued or guaranteed by the U.S. government or one of its agencies or sponsored entities, some of which may not be backed by the full faith and credit of the U.S. government. MBS represent interests in “pools” of mortgages and are subject to interest rate, prepayment, and extension risk. MBS react differently to changes in interest rates than other bonds, and the prices of MBS may reflect adverse economic and market conditions. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS. MBS are also subject to the risk of default on the underlying mortgage loans, particularly during periods of economic downturn. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to possible losses.

Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government or U.S. government agencies and authorities may cause the value of the Fund's investments to decline.

| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Risk of Investing in the China Bond Market. The Fund invests directly in the domestic bond market in the People’s Republic of China (“China” or the “PRC”) (the “China Interbank Bond Market”) through the Bond Connect trading channel. All bonds traded through Bond Connect are registered in the name of the PRC’s Central Moneymarkets Unit (“CMU”), which holds such bonds as a nominee owner. The precise nature and rights of the Fund as the beneficial owner of bonds traded in the China Interbank Bond Market through CMU as nominee are relatively new and untested areas of PRC law, and the exact nature of the Fund’s remedies and methods of enforcement of its rights and interests under PRC law are uncertain. Market volatility and potential lack of liquidity due to low trading volume of certain bonds in the China Interbank Bond Market may result in the prices of certain bonds fluctuating significantly. Also, the systems used to trade through Bond Connect may not function as expected. Trading through Bond Connect is also subject to regulatory risks, including laws and regulations that are subject to change. There can be no assurance that Bond Connect or its features or systems will not be materially altered, suspended, discontinued or abolished. The Fund may be subject to additional taxation if certain tax exemptions under PRC tax regulations are withdrawn or amended. Any taxes arising from or to the Fund may be directly borne by, or indirectly passed on to, the Fund, which may substantially impact its NAV. Investing through Bond Connect subjects the Fund to currency risk, to the extent that currency rates used for Bond Connect are different than the rates used in the China Interbank Bond Market.
