Change font size in Facebook through your browser or phone settings
Facebook itself does not have a built-in font size control in its settings menu. Instead, you adjust the text size using your device's display settings, which makes the text larger or smaller across the entire Facebook page or app. On a computer, your web browser has zoom controls. On a phone, your operating system has text size settings that affect most apps.
The method you use depends on whether you are reading Facebook on a desktop computer, laptop, tablet, or phone. Each device type has a different place to find these controls, but they all work the same way: they enlarge or shrink everything on the screen, including Facebook's text.
Key Takeaways
- Facebook does not have its own font size setting, so you use your browser's zoom feature on desktop or your phone's text size setting in the operating system.
- On Windows or Mac, hold Ctrl (or Command) and press the plus key to zoom in, or the minus key to zoom out.
- On iPhone, go to Settings > Accessibility > Display & Text Size and move the Larger Accessibility Sizes slider.
- On Android, go to Settings > Display > Font Size and choose your preferred size.
- Changes you make stay in place until you change them again, so you only need to adjust once.
Zoom in or out on a Windows or Mac computer
The fastest way to change Facebook's font size on a desktop or laptop is to use your browser's zoom feature. This works in Chrome, Firefox, Safari, and Edge. Hold down the Ctrl key (on Windows) or Command key (on Mac) and press the plus sign (+) key to make text larger. Press the minus sign (−) key to make it smaller. Each press increases or decreases the zoom by 10 percent.
You can also zoom by clicking the three-dot menu in the top right corner of your browser, then looking for a zoom option with a magnifying glass icon. Drag the slider to the right to enlarge or to the left to shrink. The zoom level stays the same the next time you open Facebook, so you will not have to reset it every visit.
If you want to reset the zoom back to normal (100 percent), hold Ctrl (or Command) and press 0 (zero). This is useful if you have zoomed in or out and want to return to the default size.
Adjust text size on an iPhone
On an iPhone, you change the text size through the Accessibility settings in your phone's operating system, not through the Facebook app itself. Open the Settings app, then tap Accessibility. Scroll down and tap Display & Text Size.
You will see a slider labeled "Larger Accessibility Sizes" with a small "A" on the left and a large "A" on the right. Drag the slider to the right to make text larger throughout Facebook and most other apps. Drag it to the left to make text smaller. The change takes effect when ready, and you can see a preview of the text size as you adjust the slider.
If you want even larger text, you can also turn on "Larger Accessibility Sizes" at the top of that same screen. This unlocks even bigger size options in the slider below. This setting affects not only Facebook but also text in Messages, Mail, Safari, and other apps on your phone.
Change font size on an Android phone
On Android, open the Settings app and tap Display. Look for an option called Font Size or Text Size (the exact name varies by phone brand). Tap it and choose from the available sizes: usually Small, Normal, Large, or Extra Large. Select the size you want and tap the back arrow or home button to save your choice.
The change takes effect when ready in Facebook and most other apps. If your phone does not have a Font Size option in Display settings, look for it under Accessibility instead. Some Android phones place text size controls there rather than in the Display menu.
You can change this setting at any time by going back to the same menu. There is no limit to how many times you can adjust it, so if a size does not feel right after a few days, you can easily switch to a different one.
What to do if text is still too small or too large
If you have already adjusted your device's text size and Facebook still does not look right, try using your browser's zoom feature in addition to the system text size. On a computer, you can zoom in on top of your existing text size setting. On a phone, you can combine the system text size with the browser's zoom if you are using Facebook in a web browser rather than the app.
If you are using the Facebook app on your phone and the text is still not the size you want, try opening Facebook in your phone's web browser instead. Then use the browser's zoom controls (usually a menu option or pinch-to-zoom gesture) to adjust the size further. This gives you more control than the app alone.
Common mistakes when changing font size
The most common mistake is looking for a font size setting inside the Facebook app itself. Facebook does not have one. If you are searching through Facebook's settings menu, you will not find a text size option there. You must use your device's settings instead.
Another mistake is forgetting that browser zoom and system text size are two separate things. If you zoom in on your browser but your system text size is set to small, the results may look odd. For the best appearance, adjust your system text size first, then use browser zoom only if you need additional adjustment.
On phones, some people change the zoom in their browser instead of using the system text size setting. This works, but it can make buttons and images harder to tap because everything becomes larger, not just the text. Using your phone's system text size setting is usually better because it scales text more intelligently.
Frequently Asked Questions
Will changing font size in Facebook affect other websites and apps?
Yes. If you adjust your browser's zoom on a computer, it affects all websites you visit in that browser until you change it back. If you adjust your phone's system text size, it affects text in most apps, including Messages, Mail, and Safari. This is usually helpful, but keep it in mind if you notice text looking different elsewhere.
Can I make the font size different for different parts of Facebook?
No. Your device's text size setting applies to the entire page or app uniformly. You cannot make comments larger while keeping the news feed smaller, for example. You can only adjust the overall zoom level.
What if I zoom in too much and cannot see the whole page?
On a computer, you can scroll left and right to see the parts of the page that are off-screen. On a phone, you can scroll in any direction. To make everything fit on the screen again, reduce the zoom by holding Ctrl (or Command) and pressing the minus key, or by adjusting your system text size back down.
Does changing font size work the same way on the Facebook website and the Facebook app?
On a computer, you only use the website, so browser zoom is your only option. On a phone, the app and the website work differently. The app responds to your system text size setting. The website responds to your browser's zoom. If one does not work well for you, try the other.
Will my font size changes stay if I log out of Facebook?
Yes. Browser zoom and system text size are device settings, not Facebook account settings. They remain in place whether you are logged in or logged out, and they persist even if you close and reopen the app or browser.
