How to Change Font Size on iPhone
To make screen content easier to read, you can increase or decrease the font size on your iPhone. You have several ways to do this, both system-wide and on an app basis. We show you your options.
Note: Your iPhone can only change the font size in Dynamic Type supported apps. These apps include Mail, Contacts, Calendar, Phone, Notes, and more. If you are unsure about an app, change the font size and see if it is reflected in your app.

Change iPhone Font Size Per App
If you want to increase or decrease the font size, but in a specific app and not system-wide, there’s an option in iOS 15 or later that lets you do it.
First, open the settings on your iPhone and tap on “Control Center”.
Choose Customize Controls.
In the More Controls section, next to Text Size, tap the green + icon. This will add the Text Size control to your Control Center.
If this item is already listed in the Include section, you don’t need to complete this step.
After the item is added to your Control Center, quit the Settings app and launch the app where you want to change the font size.
With the app open, access the Control Center and tap on the “Text Size” option. It’s a symbol with two “A’s” in it.
Tap on the app only option on the bottom left. Then use sizing to increase or decrease the font size.
In your app you will notice that your font size has changed. And you’re done.
While you’re at it, consider installing custom fonts and changing the website text size in browsers like Safari and Chrome on your iPhone.
