With iOS 14, if you changed the text size, it increased or decreased system-wide text for all iPhone apps. But in iOS 15, you can now change the text size on an app-by-app basis.
This means that if you have an app with lots of text, you can make it bigger without affecting the text on the Home Screen, in Notifications, in Settings, and in other apps. Here's how to customize the text size for individual apps on your iPhone.
How to Set Different Text Sizes for Different Apps in iOS
The standard way to change iPhone text size is to go to Settings > Display & Brightness > Text Size. This affects all apps, Home Screens, Notifications, and so on.
In iOS 15, if you want to change the text size for individual apps, you must first add a button to the iOS Control Center for text size. Once that's done, making app-specific changes to the text size is as simple as tapping that button and dragging the slider up or down.
Here are the steps to change iPhone text size in individual apps.
- Open Settings > Control Center and enable the option for Text Size. You may exit the Settings app now.
- Open the app whose text size you want to change.
- Bring up the iOS Control Center. To do this on an iPhone with Face ID, swipe down from the top-right corner. On iPhone with a Home button, swipe up from the bottom of the screen.
- Tap the AA icon.
- Tap [app name] Only and drag the slider up or down to increase or decrease the text size of that app.
If you would like to revert the app to the standard text size, open the app, bring up the Control Center, tap AA, and finally tap All Apps. This app will now have the standard system-wide text size.
Make Your iPhone Comfortable to Use With Different Text Sizes
By this point, you should know how to change an individual app's text size to make it easier on the eyes. It is also worth knowing that some apps may not honor a text size change. If that's the case, you will most likely find the switch to modify the text size inside the app settings. Plus, if the app is not updated for iOS 15, it might crash when you try to change its text size.
