How to Change Your iPhone's Text Size for a Specific App

Sometimes you want your app text to be smaller, so you can fit more content on a single screen. Sometimes you want it to be bigger, especially if you've been putting off buying those reading glasses. But until recently, if you had an iPhone, you had to choose one text size as the standard for all your apps.

Not anymore. In iOS 15, you can adjust text size separately for each of your apps. So you can, for example, keep the text small for your email, but make it a little bigger on Twitter – or vice versa. (Thanks to @OmarShahine for the info.)

If you have the iOS 15 public beta installed, here's how you can adjust the text size for each app.

First, you need to make sure the "Text Size" option is in your iOS Control Center:

  • Swipe down from the top right corner to access your control center. Check if "Text Size" is there.
  • If not, exit Control Center and go to "Settings"> "Control Center".
  • Under the "More Commands" subheading, find "Text Size" and tap the plus sign on the left to add it to your included commands. This will add it to your control center.

  • At the bottom of the screen, you'll see a toggle on the left for that specific app (for example, the left side of the toggle will say "Twitter only" and the right side will say "All apps ".) the toggle to the left.
  • Once done, use the main control in the center of the screen to set the text size for this app, then tap anywhere on the screen to return to the control center.

  • Swipe up to get rid of control center and you'll be back to your app. You should see the difference in text size immediately, but this difference will not be reflected in other applications.

And, of course, if you want to go back to standard text size, just go back to Control Center, select "Text Size" and move the bottom toggle to "All Apps". But be aware that you will reset all your apps to this text size.
