How Can I Determine the Font Used by a Web Browser?

Determining the Font Used by a Browser

Verifying the font employed by a web browser can be crucial when troubleshooting font issues. This article explores methods to determine the actual font used for a given text section.

Built-in Tools in Major Browsers

Firefox:

• Open the Page Inspector by right-clicking and selecting "Inspect Element."
• Locate the "Fonts" view, which displays all fonts used in the selected element.
• Hover over a font name to highlight the glyphs that use it.

Chrome:

• Open DevTools' "Elements" and navigate to the "Computed" tab.
• Scroll down to the "Rendered Fonts" section.
• Provides a base font name, but does not indicate specific styles.

Safari:

• As of October 2021, Safari 15 introduced a "Fonts" tab.
• Shows basic font information, but may not display multiple fonts used in an element.

Copying and Pasting into Other Applications

For browsers without dedicated font tools, copy and paste the text into a word processor or Rich Text editor:

• Select the pasted text and check the font dropdown list to identify the used font.

Note: This method may not work for special characters, as some browsers convert fonts upon pasting.

Multiple Fonts in HTML Elements

A single HTML element can use multiple fonts due to the Unicode character support. Browser tools may display separate fonts for different glyphs within the element.

Browser Variation

Different browsers, even on the same machine, may use different fonts based on support and preferences:

• Mac Safari often prefers Apple's fonts.
• Mac Firefox can use Microsoft fonts if Microsoft Office is installed.
• Browser versions can influence font selection.
