To identify the fonts used on any webpage, you can use your browser’s built-in developer tools, a browser extension, or a dedicated font-identifying website. The fastest method is to right-click on the text and select “Inspect” (or “Inspect Element”), which opens the developer tools and shows you the exact font-family name in the CSS panel. This article explains these methods in detail, plus how to identify fonts from images and what to do when the font is not a standard web font.

Formula

The calculator above computes your average running pace and speed from a given finish time and distance. The formulas are:

  • Pace (min/km) = Finish time (minutes) ÷ Distance (km)
  • Speed (km/h) = Distance (km) ÷ (Finish time (minutes) ÷ 60)

Variables:

  • t – finish time in minutes (e.g., 50 min)
  • d – distance in kilometers (e.g., 10 km)
  • pace – average pace in minutes per kilometer
  • speed – average speed in kilometers per hour

Worked Example

Using the default values (t = 50 min, d = 10 km):

  1. Pace = 50 ÷ 10 = 5.00 min/km
  2. Speed = 10 ÷ (50/60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows the same results: 5.00 min/km and 12.00 km/h.

Why Knowing the Font Matters

Fonts are a core part of a website’s identity. Designers spend hours choosing typefaces that convey the right mood—serif fonts for tradition, sans-serif for modernity, script for elegance. When you see a font you like, you might want to use it in your own project, or you might be a developer trying to match a design. Identifying a font is also the first step in licensing it correctly if you plan to use it commercially.

Method 1: Browser Developer Tools (No Extensions)

Every major browser (Chrome, Firefox, Safari, Edge) includes a built-in inspector. Here’s how to use it:

  1. Right-click on the text whose font you want to identify.
  2. Select Inspect (or Inspect Element). This opens the developer tools panel.
  3. In the Elements or Inspector tab, the selected element is highlighted. Look at the Styles or Computed pane on the right.
  4. Find the font-family property. It will list one or more font names, e.g., font-family: 'Open Sans', Arial, sans-serif;
  5. The first listed font is the primary one; the others are fallbacks.

If the font is a web font (loaded via Google Fonts or a custom @font-face rule), the developer tools will also show the font’s source file (e.g., a .woff2 URL). You can click that URL to see the font’s actual name.

Method 2: Browser Extensions

Extensions like WhatFont (for Chrome and Safari) and Font Finder (for Firefox) make the process even simpler. After installing, you just click the extension icon and then hover over the text on the page. A tooltip appears showing the font family, size, weight, and sometimes the color. These tools are especially handy when you need to identify multiple fonts on a single page quickly.

Method 3: Identify Fonts from Images

If you only have a screenshot or an image of the text, you can use a font identification service. Upload the image to WhatTheFont (by MyFonts) or Font Squirrel’s Matcherator. These tools analyze the shapes of the letters and suggest matches from their databases. For best results, crop the image to contain only the text, and make sure the letters are clear and not distorted. These services work best with high-resolution, straight-on images.

Common Problems and Misconceptions

One common issue is that the font you see is not the font that is actually loaded. This happens when the web font fails to load, and the browser falls back to a system font. The developer tools will show you the fallback in the computed style. Another misconception is that all fonts are free to use. Many fonts are licensed only for specific uses. Always check the license before using a font in your own projects, especially for commercial purposes.

How to Choose a Similar Font

If the exact font is not available or is too expensive, you can find a similar one. Use the identified font’s name as a starting point. Look for fonts with similar characteristics: x-height, stroke contrast, and overall shape. Websites like Google Fonts allow you to filter by these traits. For example, if the original is a geometric sans-serif like Futura, you might try Poppins or Montserrat as free alternatives.

Frequently Asked Questions

Can I identify a font just by looking at it?

Experienced designers can often recognize common fonts, but for most people, using a tool is more reliable. The human eye can be fooled by similar typefaces. Tools like WhatTheFont compare letter shapes with a database of thousands of fonts.

Are browser extensions safe to use?

Generally, yes, if you install them from the official browser extension stores. However, extensions can access the content of the pages you visit, so only install well-known ones with good reviews. Avoid extensions from unknown developers.

What if the font is not in the CSS?

If the font is part of an image (like a logo or a banner), the CSS won’t have the font name. In that case, use an image-based identifier. If the text is rendered by JavaScript (e.g., a canvas), the developer tools might not show it directly; look for the font in the JavaScript code or use the image method.

Do all websites use web fonts?

No. Many sites rely on system fonts (like Arial, Times New Roman, or system-ui) to load faster. These are still identifiable via the developer tools, but they are not unique to the website.

Can I use the identified font on my own site?

Only if you have the proper license. If the font is from Google Fonts, it’s open-source and free to use. If it’s a commercial font, you need to purchase a license. Check the font’s license terms before using it.
