The quickest way to change text size on Android
Open Settings, then tap Display (or Display and brightness on some phones). Look for Font size or Text size and tap it. You'll see a slider with a small "A" on the left and a large "A" on the right. Drag the slider to make text smaller or larger across most of your phone, then tap explore or Done.
The change takes effect when ready on your home screen, settings, messages, email, and most built-in apps. Some third-party apps (like social media or banking apps) may not respect this system-wide setting and will keep their own text size.
Key Takeaways
- System text size is controlled in Settings > Display > Font size or Text size, with a slider that ranges from small to large.
- Changing the system text size affects your home screen, notifications, settings menus, and most built-in Android apps when ready.
- Third-party apps often ignore the system text size and use their own settings, so you may need to adjust text size inside those apps separately.
- If you need text even larger than the maximum slider allows, Android also offers a separate accessibility setting called Display size that enlarges everything on screen.
Where to find the text size setting on different Android phones
The path to text size is nearly the same across all Android phones, but the exact wording varies slightly by manufacturer. On Samsung phones, go to Settings > Display > Font size. On Google Pixel phones, it's Settings > Display > Font size. On OnePlus, Motorola, and most other brands, the route is Settings > Display > Text size or Font size.
If you can't find it under Display, try searching for it instead. Open Settings, tap the search icon (usually a magnifying glass at the top), and type "font size" or "text size". Android will show you the exact setting on your phone and take you directly to it.
Making text larger for accessibility
If the maximum text size in the Font size slider still isn't large enough, Android has a second setting called Display size that enlarges everything on your screen — text, buttons, icons, and images. Go to Settings > Display > Display size (or Screen zoom on some phones) and drag the slider to the right. This setting magnifies the entire interface, not just text.
You can use both settings together. For example, you might set Display size to large and Font size to medium to get the exact size you need. Note that making the display size very large may cause some apps to display oddly or cut off text at the edges, so test it with the apps you use most.
Changing text size in individual apps
Many apps have their own text size controls that override the system setting. In Gmail, open a message, tap the three-dot menu, and look for Text size. In Chrome, tap the three-dot menu, go to Settings, then Accessibility, and adjust Text scaling. In Facebook, go to Settings & Privacy > Settings > Accessibility, then look for text size options.
The location of text size controls varies widely between apps, so if you don't see it in the main menu, check the app's settings or accessibility section. Some apps don't offer text size control at all and will always use whatever size the system is set to.
What happens when you change text size
Changing the system text size affects notifications, menus, labels, and most text you see on your phone. Your home screen widget text, clock display, and app names will all get larger or smaller. The change is when ready — you don't need to restart your phone or close any apps.
Some apps may need to reload to show the new text size, and a few apps may not respond to the change at all. If an app's text doesn't change after you adjust the system setting, that app is using its own fixed text size and you'll need to adjust it within the app itself.
Undoing or resetting text size to default
To return text to the default size, go back to Settings > Display > Font size and drag the slider back to the middle position. The middle position is the standard size Android ships with. If you're not sure where the middle is, look for a dot or line on the slider that marks the default.
If you've also changed Display size, reset that separately by going to Settings > Display > Display size and moving the slider back to the center. Both changes take effect when ready.
Frequently Asked Questions
Does changing text size affect battery life?
No. Text size is purely a display setting and has no effect on how much power your phone uses. Making text larger or smaller won't drain your battery faster or slower.
Why doesn't text size change in some apps?
Some apps, especially social media and banking apps, ignore the system text size and use their own built-in settings instead. You'll need to look for a text size or font size option inside that app's settings or accessibility menu.
Can I set different text sizes for different apps?
Not through the system setting. The system text size applies to all apps that respect it. You can adjust text size individually in apps that have their own controls, but you can't tell the system to use one size for Gmail and another for Messages.
What's the difference between Font size and Display size?
Font size makes text larger while keeping everything else the same size. Display size magnifies your entire screen — text, buttons, icons, and images all get bigger together. Use Font size for text-only adjustments and Display size when you need everything enlarged.
