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.

Shareholder Fees Caption [Text] rr_ShareholderFeesCaption Shareholder fees (fees paid directly from your investment)
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 10.0% of the average value of its portfolio.

Portfolio Turnover, Rate rr_PortfolioTurnoverRate 10.00%
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 mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the previous table; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. 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 65% of the fund’s total assets in stocks, with an emphasis on stocks that have a strong track record of paying dividends or that are expected to increase their dividends over time.

The adviser believes that a track record of dividend increases can be an excellent indicator of financial health and growth prospects, and that over the long term, income can contribute significantly to total return. Dividends can also help reduce the fund’s volatility during periods of market turbulence and help offset losses when stock prices are falling.

The adviser’s research analysts look for stocks with sustainable, above-average growth in earnings and dividends. When appropriate, the portfolio manager may attempt to buy stocks when they are temporarily out of favor or undervalued by the market. Holdings tend to be in large- and mid-cap companies.

At times, the fund may have a significant portion of its assets invested in the same economic sector.

In selecting investments, the adviser generally favors companies that it believes possess one or more of the following:

· either a track record of, or the potential for, above-average earnings and dividend growth;

· a competitive current dividend yield;

· a sound balance sheet and solid cash flow to support future dividend increases;

· a sustainable competitive advantage and leading market position; and

· attractive valuations, such as low price/earnings, price/cash flow, or price/sales ratios.

While most assets are typically invested in U.S. common stocks, the fund may invest in foreign stocks in keeping with its objective(s).

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 Dividend Growth Fund, Inc. | Dividend-paying stocks  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Dividend-paying stocks: The fund’s emphasis on dividend-paying stocks could cause the fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. Stocks of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other stocks, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend.

T. Rowe Price Dividend Growth Fund, Inc. | 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 Dividend Growth Fund, Inc. | 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 Dividend Growth Fund, Inc. | Large- and mid-cap stocks  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Large- and mid-cap stocks: Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by small-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges. The fund’s share price could fluctuate more than the share price of a fund that invests only in large-cap companies as stocks of mid-cap companies entail greater risk and are usually more volatile than stocks of large-cap companies.

T. Rowe Price Dividend Growth Fund, Inc. | Sector exposure  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Sector exposure: Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

T. Rowe Price Dividend Growth Fund, Inc. | Foreign investing  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Foreign investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity and trading volume than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. The fund’s overall foreign investing risk is increased to the extent it has exposure to emerging markets.

T. Rowe Price Dividend Growth Fund, Inc. | 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.

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.
