Change font size in Facebook settings

Facebook does not have a built-in font size control inside the app or website. Instead, you adjust text size through your device's accessibility settings, which affects Facebook along with every other app and website you use. The steps differ depending on whether you are on a phone, tablet, or computer.

On any device, larger text makes Facebook easier to read without opening your eyes wider or holding the screen closer. The change applies when ready and stays in place until you adjust it again.

Key Takeaways

  • Facebook itself has no font size button; you change text size through your phone, tablet, or computer settings instead.
  • On iPhone, go to Settings > Accessibility > Display & Text Size > Larger Accessibility Sizes to increase text across all apps.
  • On Android, open Settings > Accessibility > Display and Text > Font Size and move the slider to your preferred size.
  • On Windows or Mac, use your browser's zoom feature (Ctrl or Command plus the plus key) to enlarge Facebook text without changing your whole system.
  • Text size changes stay in place across all apps and websites until you manually adjust them again.

Increase font size on iPhone

Open the Settings app on your home screen. Scroll down and tap Accessibility, then tap Display & Text Size.

Tap Larger Accessibility Sizes. A slider appears at the bottom of the screen showing text size options from smallest to largest. Drag the slider to the right to make text bigger. As you move it, you will see a preview of how the text will look. Tap the back arrow when you are satisfied with the size.

Return to Facebook and the text will be larger throughout the app. This setting affects not just Facebook but all apps on your phone that respect system text size settings.

Increase font size on Android

Open the Settings app. Tap Accessibility (sometimes labeled as "Accessibility" under System settings, depending on your phone model). Tap Display and Text, then tap Font Size.

A slider appears with size options. Move it to the right to increase text size. You will see a preview labeled "Sample Text" showing how large the font will become. Tap the back arrow or the checkmark to save your choice.

Open Facebook and the text will be larger. Like iPhone, this change affects all apps that use the system font size setting, not just Facebook.

Enlarge text on Windows or Mac

If you use Facebook in a web browser on a computer, use your browser's zoom feature instead of system settings. This lets you enlarge Facebook without making everything else on your screen larger.

Hold down Ctrl (Windows) or Command (Mac) and press the plus key (+) to zoom in. Each press makes the text and images slightly larger. Press it multiple times until Facebook is the size you want. To zoom back out, hold Ctrl or Command and press the minus key (−). To return to normal size, hold Ctrl or Command and press 0 (zero).

Your zoom level stays in place for Facebook each time you visit, but does not affect other websites unless you zoom them separately.

Use browser text size settings

Most browsers also have a dedicated text size control in their settings. In Chrome, click the three-dot menu in the top right, then look for a zoom slider or text size option. In Firefox, click the three horizontal lines menu, scroll to the bottom, and adjust the zoom level. In Safari on Mac, click Safari in the top menu, then Preferences, and look for the default font size option.

These browser settings work the same way as the keyboard shortcut: they enlarge text on the current website without affecting your system settings or other websites.

What happens if text is still too small

If you have already increased your phone or tablet's font size to the largest option and Facebook text is still difficult to read, try using your browser's zoom feature on a computer instead. Computer browsers often allow larger zoom levels than phone accessibility settings.

You can also try switching to Facebook's dark mode, which some people find easier to read because the contrast between text and background is higher. Open Facebook, tap the menu icon (three horizontal lines), scroll down, tap Settings & Privacy, then Settings, then Accessibility, and toggle Dark Mode on.

Frequently Asked Questions

Does changing font size on my phone affect only Facebook or all apps?

It affects all apps on your phone that respect system accessibility settings. Some older or less common apps may not respond to the change. Facebook, Instagram, Gmail, and most major apps will show the larger text when ready.

If I zoom in on Facebook in my browser, will it zoom other websites too?

No. Browser zoom is per-website. If you zoom Facebook to 150%, other websites you visit will stay at 100% unless you zoom them separately. Each site remembers its own zoom level.

Can I make font size different for Facebook than for other apps?

Not on phones or tablets — system font size applies to all apps at once. On a computer, you can use browser zoom to enlarge only Facebook while leaving other websites at normal size.

Will Facebook text get smaller again if I restart my phone?

No. Font size changes are saved permanently in your accessibility settings. They stay in place until you manually change them again.
