Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading <span style="color:#000000;font-family:Arial;font-size:12pt;font-weight:bold;">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 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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 217.11% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This Example is intended to help you to compare the cost of investing in the Fund with the cost of investing in other mutual 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 time periods. It assumes a 5% return each year and no change in expenses, and any expense limitation or fee waivers that may apply for the periods indicated above under “Fees and Expenses.” 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:12pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of U.S issuers. Equity securities that the Fund buys primarily are common stocks of large-cap companies, i.e., those with market capitalizations similar to those of companies included in the S&P 500 Index. The Fund makes market capitalization determinations with respect to a security at the time of its purchase. The Fund may invest in equity securities of foreign companies in both developed and emerging markets. Although the Fund typically invests in seasoned issuers, it may, depending on the appropriateness to the Fund’s strategy and availability in the marketplace, purchase securities of companies in initial public offerings (IPOs) or shortly thereafter, which can be subject to greater volatility than seasoned issuers. The Fund’s subadviser seeks to capture market inefficiencies which it believes are driven by investors’ propensity to be short-sighted and overly focused on quarter-to-quarter price movements, rather than a company’s fundamentals over a longer time horizon (5 years or more). The subadviser believes that this market inefficiency may lead investors to underappreciate the compounding potential of quality, growing companies. To identify this subset of companies, the subadviser generates investment ideas from a variety of sources, ranging from institutional knowledge and industry contacts, to the subadviser’s proprietary screening process that seeks to identify suitable companies based on several quality factors, such as rates of return on equity and total capital, margin stability and profitability. Ideas are then subject to rigorous fundamental analysis as the subadviser seeks to identify and invest in companies that it believes reflect higher quality opportunities on a forward-looking basis. Specifically, the subadviser seeks to buy companies that it believes are reasonably priced and have strong fundamental business characteristics and sustainable and durable earnings growth. The subadviser seeks to outperform peers over a full market cycle by seeking to capture market upside while limiting downside risk. For these purposes, a full market cycle can be measured from a point in the market cycle (e.g., a peak or trough) to the corresponding point in the next market cycle. Subject to the subadviser's criteria for quality, many of the stocks in which the Fund invests may be considered to be “growth” stocks, in that they may have above-average rates of earnings growth and thus may experience above-average increases in stock prices. The Fund also may purchase stocks that would not fall into the traditional “growth” style box. In constructing a portfolio of securities, the subadviser is not constrained by sector or industry weights of the Fund’s benchmark. The Fund may invest in any economic sector and, at times, emphasize one or more particular industries or sectors. The subadviser relies on individual stock selection driven by a bottom-up research process rather than seeking to add value based on “top-down,” macro-based criteria. The subadviser may sell a stock if the subadviser believes that the company’s long-term competitive advantage or relative earnings growth prospects have deteriorated, or the subadviser has otherwise lost conviction that the company reflects a higher quality opportunity relative to other available investments on a forward-looking basis. The subadviser also may sell a stock if the company has met its price target or is involved in a business combination, if the subadviser identifies a more attractive investment opportunity, or the subadviser wishes to reduce the Fund’s exposure to the company or a particular country or geographic region. The Fund may engage in frequent and active trading of portfolio securities. The Fund is classified as a “non-diversified fund” under the Investment Company Act of 1940, which means that a relatively high percentage of the Fund’s assets may be invested in a limited number of issuers.
Risk [Heading] rr_RiskHeading <span style="color:#000000;font-family:Arial;font-size:12pt;font-weight:bold;">Principal Risks</span>
Risk [Text Block] rr_RiskTextBlock The Fund cannot guarantee that it will achieve its investment objective. As with any fund, the value of the Fund’s investments—and therefore, the value of Fund shares—may fluctuate. These changes may occur because of:Loss of money is a risk of investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The following bar chart and table can help you evaluate the Fund’s potential risks. The bar chart shows how the Fund’s annual total returns have varied from year to year. The table compares the Fund’s average annual total returns to the returns of a broad-based securities market index. Remember, however, that past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future. Updated performance information is available at no cost by visiting nationwide.com/mutualfundsor by calling 800-848-0920. Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

Nationwide GQG US Quality Equity Fund | Risk Lose Money [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Loss of money is a risk of investing in the Fund.
Nationwide GQG US Quality Equity Fund | Equity Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Equity securities risk – stock markets are volatile. The price of an equity security fluctuates based on changes in a company’s financial condition and overall market and economic conditions.
Nationwide GQG US Quality Equity Fund | Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Market risk – the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. This occurs due to numerous factors, including interest rates, the outlook for corporate profits, the health of the national and world economies, and the fluctuation of other securities markets around the world. These risks may be magnified if certain social, political, economic and other conditions and events (such as natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest or rapid technological developments such as artificial intelligence) adversely interrupt the global economy.
Nationwide GQG US Quality Equity Fund | Selection Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Selection risk – the risk that the securities selected by the Fund’s subadviser will underperform the markets, the relevant indexes or the securities selected by other funds with similar investment objectives and investment strategies.
Nationwide GQG US Quality Equity Fund | Growth Stocks Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Growth stocks risk – growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. If the subadviser’s assessment of the prospects for a company’s growth is wrong, or if the subadviser’s judgment of how other investors will value the company’s growth is wrong, then the Fund may suffer a loss as the price of the company’s stock may fall or not approach the value that the subadviser has placed on it. In addition, growth stocks as a group may be out of favor at times and underperform the overall equity market for long periods while the market concentrates on other types of stocks, such as “value” stocks.
Nationwide GQG US Quality Equity Fund | Foreign Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Foreign securities risk – foreign securities often are more volatile, harder to price and less liquid than U.S. securities. The prices of foreign securities may be further affected by other factors, such as changes in the exchange rates between the U.S. dollar and the currencies in which the securities are traded.
Nationwide GQG US Quality Equity Fund | Emerging Markets Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Emerging markets risk – emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets are considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. Since these markets are smaller than developed markets, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries are unreliable compared to developed markets. Companies in emerging market countries generally are subject to less stringent financial reporting, accounting and auditing standards than companies in more developed countries. In addition, information about such companies may be less available and reliable. Many emerging markets also have histories of political instability and abrupt changes in policies, and the ability to bring and enforce actions may be limited. Certain emerging markets also face other significant internal or external risks, including the risk of war, nationalization of assets, unexpected market closures and ethnic, religious and racial conflicts.
Nationwide GQG US Quality Equity Fund | Sector Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Sector risk – investments in particular industries or sectors may be more volatile than the overall stock market. Therefore, if the Fund emphasizes one or more industries or economic sectors, it will be more susceptible to financial, market or economic events affecting the particular issuers and industries participating in such sectors than funds that do not emphasize particular industries or sectors.
Nationwide GQG US Quality Equity Fund | Initial Public Offering Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Initial public offering risk – availability of IPOs may be limited and the Fund may not be able to buy any shares at the offering price, or may not be able to buy as many shares at the offering price as it would like, which may adversely impact Fund performance. Further, IPO prices often are subject to greater and more unpredictable price changes than more established stocks.
Nationwide GQG US Quality Equity Fund | Nondiversified Fund Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Nondiversified fund risk – because the Fund may hold larger positions in fewer securities than diversified funds, a single security’s increase or decrease in value may have a greater impact on the Fund’s value and total return.
Nationwide GQG US Quality Equity Fund | Redemptions Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Redemptions risk – the Fund is an investment option for other mutual funds that are managed as “funds-of-funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments. Large or continuous redemptions may increase the Fund’s transaction costs and could cause the Fund’s operating expenses to be allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. If funds-of-funds or other large shareholders redeem large amounts of shares rapidly or unexpectedly, the Fund may have to sell portfolio securities at times when it would not otherwise do so, which could negatively impact the Fund’s net asset value and liquidity.
Nationwide GQG US Quality Equity Fund | Portfolio Turnover Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Portfolio turnover risk – a higher portfolio turnover rate increases transaction costs, may adversely impact the Fund’s performance, and may result in higher taxes when Fund shares are held in a taxable account.
