Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Fund seeks to track the performance of a market-weighted corporate bond index that measures the investment return of investment-grade U.S. dollar-denominated bonds and is screened for certain environmental, social, and corporate governance criteria.
Expense [Heading]	rr_ExpenseHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Fees and Expenses</span>
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The following tables describe the fees and expenses you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and example below.

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<span style="color:#000000;font-family:Arial;font-size:9.5pt;">Portfolio Turnover</span>
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). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	<span style="color:#000000;font-family:Arial;font-size:9.5pt;">Example</span>
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is intended to help you compare the cost of investing in the Fund’s ETF Shares with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund’s shares. This example assumes that the shares provide a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to sell your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund employs an indexing investment approach designed to track the performance of the Bloomberg MSCI US Corporate SRI Select Index (the Index). The Index is a subset of the Bloomberg U.S. Corporate Index (the Parent Index), which serves as the universe of eligible bonds for use in constructing the Index and represents U.S. dollar-denominated, taxable, investment-grade corporate bonds. The Index excludes bonds with maturities of less than 1 year and with less than $750 million outstanding, and is screened for certain environmental, social, and governance (ESG) criteria by the Index provider, which is independent of Vanguard. The Index excludes the bonds of companies that the Index provider determines engage in (which may include manufacturing, owning, and operating), have a specified level of involvement in, and/or derive threshold amounts of revenue from certain activities or business segments related to the following: adult entertainment, alcohol, gambling, tobacco, nuclear weapons, controversial weapons, conventional weapons, civilian firearms, nuclear power, and thermal coal, oil, or gas. The level or type of involvement in, or amount of revenue earned from, certain activities or business segments that lead to exclusion by the Index provider can vary from one activity or business segment to another. The Index also excludes the bonds of any company that, as determined by the Index provider, does not meet certain standards defined by the Index provider with respect to an ESG controversies assessment, which measures a company’s involvement in major ESG controversies and how well they adhere to international norms and principles, or does not have an ESG controversy assessment score. Where MSCI, the Index provider’s data source, has insufficient or no data available to adequately assess a particular issuer relative to the ESG criteria of the Index, bonds of such issuer may be excluded from the Index until such time as they may be determined to be eligible by MSCI. Additionally, the Index excludes bonds of companies that fail to have at least one woman on their board of directors and companies for which the Index provider does not have board diversity data. The screens for ESG criteria described above do not apply to government-issued bonds (e.g., U.S. Treasury securities), asset-backed securities, mortgage-backed securities, and commercial mortgage-backed securities.The Fund invests by sampling the Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. All of the Fund’s investments will be selected through the sampling process, and under normal circumstances, at least 80% of the Fund’s assets will be invested in bonds included in the Index. The Fund seeks to maintain a dollar-weighted average maturity consistent with that of the Index.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Risks</span>
Risk [Text Block]	rr_RiskTextBlock	• Credit risk, which is the chance that a bond issuer will fail to pay interest or principal in a timely manner or that negative perceptions of the issuer’s ability to make such payments will cause the price of that bond to decline.• Interest rate risk, which is the chance that bond prices will decline because of rising interest rates. Interest rate risk should be low for short-term bond funds, moderate for intermediate-term bond funds, and high for long-term bond funds.• Income risk, which is the chance that the Fund’s income will decline because of falling interest rates. Income risk is generally higher for short-term bond funds and lower for long-term bond funds.• Liquidity risk, which is the chance that a Fund may not be able to sell a security in a timely manner at a desired price.• Index-related risks. The Fund is subject to risks associated with index investing, which include passive management risk, tracking error risk, and index provider risk. Passive management risk is the chance that the Fund’s use of an indexing strategy will negatively impact the Fund’s performance. Because the Fund seeks to track the performance of its target index regardless of how that index is performing, the Fund’s performance may be lower than it would be if the Fund were actively managed. Tracking error risk is the chance that the Fund’s performance will deviate from the performance of its target index. Tracking error risk may be heightened during times of increased market volatility or under other unusual market conditions. Index provider risk is the chance that the Fund will be negatively impacted by changes or errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund’s shareholders.• Index sampling risk, which is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund’s target index.• ESG investing risks. The Fund is subject to ESG investing risks. The index provider selects securities for the Index based on the ESG criteria disclosed in the Fund’s principal investment strategies. Using ESG criteria could result in the Fund investing in securities that trail the returns of other funds that use ESG criteria or in the Fund underperforming the market as a whole. The index provider’s use of ESG criteria may result in the Index becoming focused, at times, in a particular market sector, which would subject the Fund to proportionately higher risks of that sector. Interpretations of what it means for a company or issuer to exhibit ESG characteristics can—and do—vary significantly across individuals, index providers, advisors, and other funds that use ESG criteria. As a result, the Fund’s disclosed ESG criteria, or the index provider’s assessment of whether or not a company or issuer meets the Fund’s disclosed ESG criteria, may not align with your personal view of what it means for a company or issuer to exhibit ESG characteristics. Further, individual securities held by the Fund may not reflect your personal preferences, beliefs, expectations, and/or values. In order to assess a company or issuer against the Fund’s disclosed ESG criteria, the index provider depends on the availability of data obtained through voluntary or third-party reporting. There can be no assurance that this data will be accurate, complete, or current, which could result in an inaccurate assessment of a company or issuer.Because the Fund is an exchange-traded fund (ETF) and the Fund’s shares are traded on an exchange, the Fund is subject to additional risks:• The Fund’s ETF Shares are listed for trading on Cboe BZX Exchange, Inc. and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.• Although the Fund’s ETF Shares are listed for trading on Cboe BZX Exchange, Inc., it is possible that an active trading market may not be maintained.• Trading of the Fund’s ETF Shares may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Fund’s ETF Shares may also be halted if (1) the shares are delisted from Cboe BZX Exchange, Inc. without first being listed on another exchange or (2) Cboe BZX Exchange, Inc. officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Annual Total Returns</span>
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s ETF Shares (based on NAV) has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the ETF Shares compare with those of the Fund’s target index and other comparative indexes, which have investment characteristics similar to those of the Fund. The Fund is using a comparative benchmark that is different from the one used for the immediately preceding fiscal year to reflect new regulatory requirements. The Bloomberg U.S. Aggregate Bond Index is considered broadly representative of the overall securities market applicable to the Fund. Keep in mind that the Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. Updated performance information is available on our website at vanguard.com/performance.
