Where to find text size settings on Android
Text size on Android lives in your phone's accessibility settings, not in individual apps. Open Settings, then tap Accessibility (sometimes called Accessibility and display depending on your phone maker). Look for Text and display or Display and text, then tap Font size or Text size. You'll see a slider with a preview of how your text will look at each size.
The exact path varies slightly by manufacturer. Samsung phones label it Settings > Accessibility > Visibility enhancements > Font size. Google Pixel phones use Settings > Accessibility > Display and text > Font size. If you can't find it, search "font size" in your Settings app — Android will take you directly there.
Key Takeaways
- Text size settings are in Accessibility, not in individual app settings, so one change affects most of your phone.
- You can choose from five preset sizes using a slider, and you'll see a live preview before you confirm.
- Some apps ignore system text size and use their own settings, so you may need to adjust text size within those apps separately.
- If text is still too small after maxing out the system setting, you can also increase your overall display zoom in the same Accessibility menu.
Using the text size slider
Once you're in the Font size menu, you'll see five options ranging from smallest to largest. The slider shows you exactly how your text will appear at each size — look at the preview text that says "Sample text" or similar. Tap the size you want, and your phone updates immediately. There's no "save" button; your choice takes effect right away.
The smallest size is useful if you want to fit more information on screen at once. The largest is helpful if you find yourself squinting at notifications, messages, or settings. Most people land somewhere in the middle two sizes. If none of the five preset sizes feel quite right, you've hit the limit of this setting — you'll need to use display zoom instead.
When apps ignore your text size choice
Some apps, particularly older ones or those designed by smaller developers, don't respect your system text size setting. You might set your phone to the largest size and still see tiny text in certain apps. This happens because the app was built to use its own fixed text size rather than following your phone's accessibility settings.
If an app ignores your system setting, check whether that app has its own text size option. Open the app, go to its settings or preferences (usually a gear icon or menu), and look for "text size", "font size", or "display". Many apps like Chrome, Gmail, and Kindle have their own text controls. If the app has no text size option and the text is genuinely unreadable, you can increase your overall display zoom as a workaround.
Using display zoom when text size isn't enough
If you've maxed out the text size slider and text is still too small, your next option is display zoom or screen zoom. This enlarges everything on your screen — text, buttons, icons, and images — not just text. Go to Settings > Accessibility > Display and text > Display size (or Screen zoom on Samsung). You'll see a slider with options from smallest to largest.
Display zoom is more aggressive than text size alone. It can make your phone harder to navigate because buttons and text boxes become larger and take up more space, sometimes forcing you to scroll more. Use it only if text size alone doesn't solve the problem. You can combine both settings — for example, set text size to large and display zoom to medium — to get the exact size you need.
Changing text size in specific apps
Beyond system settings, many popular apps let you control text size within the app itself. In Chrome, tap the three-dot menu, go to Settings > Accessibility, and adjust text scaling. In Gmail, open a message, tap the three-dot menu, and choose Text size. In Kindle, open a book, tap the screen, tap the font icon, and select your size.
These app-level settings override your system text size for that app only. If you prefer larger text in one app but normal text everywhere else, this is the way to do it. Check the settings or preferences menu of any app where you struggle to read text — the option is often there, just not always in an obvious place.
Reverting to default text size
If you change your text size and later want to go back to the default, return to Settings > Accessibility > Text and display > Font size and tap the middle option on the slider. This is usually the second or third size, marked as the standard or default. Your text will return to the size it was when you first got your phone.
If you've also changed display zoom and want to reset that, go to Settings > Accessibility > Display and text > Display size and select the middle option there as well. You can reset text size and display zoom independently — changing one doesn't affect the other.
Frequently Asked Questions
Will changing text size affect my battery life?
No. Text size is purely a display setting and doesn't change how hard your phone's processor or battery works. Larger text uses the same amount of power as smaller text.
Can I set different text sizes for different apps?
Your system text size applies to most apps at once. However, individual apps like Chrome, Gmail, and Kindle have their own text size controls that override the system setting for just that app. Check the app's settings menu to see if it offers this option.
What's the difference between text size and display zoom?
Text size enlarges only the words and letters. Display zoom enlarges everything — text, buttons, icons, and images. Use text size first; if that's not enough, add display zoom on top of it.
Why is text still tiny even after I set it to the largest size?
The app you're using may ignore system text size settings. Check whether that app has its own text size option in its settings menu. If not, use display zoom as a workaround, though this will enlarge everything on your screen, not just text.
Do I need to restart my phone after changing text size?
No. Text size changes take effect immediately. You'll see the new size as soon as you close the Settings app.
