| Expense [Heading] | rr_ExpenseHeading | Fees and Expenses | ||||||||||||||||||||||||||||
| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below. |

| Operating Expenses Caption [Text] | rr_OperatingExpensesCaption | Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment) | ||||||||||||||||||||||||||||
| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover | ||||||||||||||||||||||||||||
| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | Portfolio Turnover The fund pays 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 the fund’s 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. During the most recent fiscal year, the fund’s portfolio turnover rate was 21.2% of the average value of its portfolio. |

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example | ||||||||||||||||||||||||||||
| 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 funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then sell all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s fees and expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||||||||||||||||||||
| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies with growth characteristics. For purposes of the fund’s 80% investment policy, the fund considers a company to have growth characteristics if the company’s securities are represented in an appropriate third-party growth-oriented index. Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy. The fund invests primarily in U.S. equity securities and uses a growth style of investing. The adviser looks for companies with an above-average rate of earnings, cash flow growth, and a lucrative niche in the economy that gives them the ability to sustain earnings momentum even during times of slow economic growth. The fund may purchase the stocks of companies of any size, but typically focuses on large-cap companies. The portfolio is typically constructed in a “bottom up” manner, an approach that focuses more on evaluations of individual stocks than on analysis of overall economic trends and market cycles. Sector allocations are largely the result of the fund’s focus on stock selection. At times, the fund may have a significant portion of its assets invested in the same economic sector, such as the information technology sector. The fund is nondiversified, which means it may invest a greater percentage of its assets in a particular issuer than is permissible for a diversified fund. |

| T. Rowe Price Growth ETF | Risk Lose Money [Member] | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | The fund’s share price fluctuates, which means you could lose money by investing in the fund. | ||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Growth investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Growth investing: The fund’s growth approach to investing could cause it to underperform other stock funds that employ a different investment style. Growth stocks tend to be more volatile than certain other types of stocks and their prices may fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Market conditions | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including economic, political, or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses (including sanctions). Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Stock investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Risk Nondiversified Status [Member] | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Nondiversification: As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The fund’s share price can be expected to fluctuate more than that of a similar fund that is more broadly diversified. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Large-cap stocks | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large-cap stocks: Securities issued by large-cap companies tend to be less volatile than securities issued by small- and mid-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small- and mid-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Sector exposure | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Sector exposure: To the extent the fund invests in specific industries or sectors, it may be more susceptible to developments affecting those industries and sectors. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Information technology sector | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Information technology sector: Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources, or personnel. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Authorized Participant | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Authorized Participant: Only an Authorized Participant may engage in creation or redemption transactions directly with the fund. The fund has a limited number of intermediaries that act as Authorized Participants, and none of these Authorized Participants are or will be obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the fund and no other Authorized Participant is able to step forward to create or redeem, (i) the market price of the fund’s shares may trade at a premium or discount to its net asset value (NAV), (ii) an active trading market for the fund may not develop or be maintained, and (iii) there is no assurance that the requirements of the exchange necessary to maintain the listing of the fund will continue to be met or remain unchanged. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | ETF shares trading | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | ETF shares trading: Shares of the fund are listed for trading on a national securities exchange and are bought and sold in the secondary market at market prices. The market prices of shares are expected to fluctuate in response to changes in the fund’s NAV, the value of the fund’s holdings, and supply and demand for shares. Disruptions to creations and redemptions, significant market volatility, potential lack of an active trading market for the shares (including through a trading halt), or other factors may widen bid-ask spreads and result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the value of the fund’s holdings. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | New fund | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | New fund: Because the fund is new, it has a relatively small number of shareholders and assets under management. As a result, the portfolio manager may experience difficulties in fully implementing the fund’s investment program and may be less able to respond to increases in shareholder transaction activity. The fund’s limited operating history could make it more difficult to evaluate the performance of the portfolio manager and the fund’s investment strategies. In addition, there can be no assurance that the fund will ultimately grow to an economically viable size, which could lead to the fund eventually ceasing its operations. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Active management | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Active management: The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth ETF | Cybersecurity breaches | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality. |
