| Objective [Heading] | rr_ObjectiveHeading | Investment Objective(s) |
| Objective, Primary [Text Block] | rr_ObjectivePrimaryTextBlock | The fund seeks the highest level of income exempt from federal income taxes consistent with moderate price fluctuation. |
| 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. For the period July 9, 2024 through October 31, 2024, the fund’s portfolio turnover rate was 91.6% 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 investment-grade municipal securities or derivatives that are linked to or provides investment exposure to the municipal market. Investment grade means securities that are rated in one of the four highest rating categories assigned by a credit rating agency or, if unrated, deemed by the adviser to be of comparable quality. 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. Under normal conditions, the fund’s weighted average effective maturity will be four to twelve years. There are no maturity limitations on individual securities. The fund primarily invests in tax-exempt securities. However, a significant portion of the fund’s income could be derived from securities subject to the alternative minimum tax. The fund may also invest in the securities of issuers whose revenues are generated from similar types of projects or operate in similar business sectors, including healthcare, transportation, utilities, or private activity bonds. The fund may have significant exposure to specific states under some circumstances. The fund may invest in below investment-grade instruments, such holdings are commonly referred to as “junk”. Investment decisions generally reflect the portfolio manager’s outlook for interest rates and the economy, as well as the prices, yields, and credit quality of various securities in which the fund may invest. |

| T. Rowe Price Intermediate Municipal Income 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 Intermediate Municipal Income ETF | Municipal securities | ||
| Risk/Return: | rr_RiskReturnAbstract | |
| Risk [Text Block] | rr_RiskTextBlock | Municipal securities: The fund may be highly impacted by events tied to the overall municipal securities markets, which can be very volatile and significantly affected by unfavorable legislative or political developments and adverse changes in the financial conditions of municipal securities issuers and the global, national, and/or local economies. Income from municipal securities held by the fund could become taxable because of changes in tax laws or interpretations by taxing authorities, or noncompliant conduct of a state or municipality. Other changes in tax laws, including changes to individual or corporate tax rates, could alter the attractiveness and overall demand for municipal bonds. Certain sectors of the municipal bond market have special risks and could be affected by certain developments more significantly than the market as a whole. For example: health care can be negatively impacted by rising expenses and dependency on third party reimbursements; transportation can be negatively impacted by declining revenues or unexpectedly high construction or fuel costs; utilities are subject to governmental rate regulation; and private activity bonds (including industrial development bonds) rely on project revenues and the creditworthiness of the corporate user as opposed to governmental support. Investing significantly in municipal obligations backed by revenues of similar types of industries or projects may make the fund more susceptible to developments affecting those industries and projects. If the fund invests a substantial amount of its assets in issuers located in a single region, state, or city, there is an increased risk that environmental, economic, political, and social conditions in those regions will have a significant impact on the fund’s investment performance. |
| T. Rowe Price Intermediate Municipal Income ETF | Alternative minimum tax | ||
| Risk/Return: | rr_RiskReturnAbstract | |
| Risk [Text Block] | rr_RiskTextBlock | Alternative minimum tax: Although the fund seeks to distribute tax-exempt income, a portion of the fund’s otherwise tax-exempt dividends may be taxable to those shareholders subject to the federal alternative minimum tax. |
| T. Rowe Price Intermediate Municipal Income 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 Intermediate Municipal Income ETF | Credit quality | ||
| Risk/Return: | rr_RiskReturnAbstract | |
| Risk [Text Block] | rr_RiskTextBlock | Credit quality: An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative. Economic downturns often result in reduced levels of taxes collected and revenues earned by municipalities and insufficient funding to meet pension or health care obligations, which could lessen the overall financial strength of a municipality and increase the credit risk of the securities it issues. The fund’s credit risk is increased to the extent it invests in securities that are not backed by the taxing power of the municipal issuer. |
| T. Rowe Price Intermediate Municipal Income ETF | Junk investing | ||
| Risk/Return: | rr_RiskReturnAbstract | |
| Risk [Text Block] | rr_RiskTextBlock | Junk investing: Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, expose the fund to greater volatility and credit risk than investments in bonds that are rated investment grade. |
| T. Rowe Price Intermediate Municipal Income ETF | Interest rates | ||
| Risk/Return: | rr_RiskReturnAbstract | |
| Risk [Text Block] | rr_RiskTextBlock | Interest rates: A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests. |
| T. Rowe Price Intermediate Municipal Income ETF | Callable bonds | ||
| Risk/Return: | rr_RiskReturnAbstract | |
| Risk [Text Block] | rr_RiskTextBlock | Callable bonds: While a rise in interest rates is the principal source of interest rate risk for bond funds, falling rates bring the possibility that a bond may be “called,” or redeemed before maturity, and that the proceeds may need to be reinvested in lower-yielding securities. |
| T. Rowe Price Intermediate Municipal Income ETF | Liquidity | ||
| Risk/Return: | rr_RiskReturnAbstract | |
| Risk [Text Block] | rr_RiskTextBlock | Liquidity: The fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. The secondary market for certain municipal bonds tends to be less developed and less liquid than many other bond markets. Less liquid markets could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price. |
| T. Rowe Price Intermediate Municipal Income 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 Intermediate Municipal Income 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 Intermediate Municipal Income 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 Intermediate Municipal Income 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. |
