With the individual text size, you can have smaller text in the social media apps and larger fonts for your email app – just to make important things easier to read.

The option is available for iPhone running iOS 15 or later to adjust text size for individual apps. All iPhone devices launched after the iPhone 6S support this feature. Here’s how you can enable it.

Step 3: This will add the Text Size toggle to the control center. You can pull down from the top-right edge of your iPhone to verify if the toggle appears in the Control Center. If you’re using an iPhone with a home button, swipe up from the bottom to access the control center.

Note that instead of the ‘+’ icon you see a red ‘-‘ icon next to Text Size, it indicates that the Text Size toggle is already present in the control center. In such a case, you don’t have to change anything in this menu.

100% is the default text size, Swiping up will increase it up to 310%, and swiping down will reduce it to 80%. The words ‘Text Size’ at the top of the screen and the percentage value displayed below it is indicative of the current text size so you can use that for reference.

Step 7: Once you have set your desired text size, drag the horizontal slider at the bottom to Settings Only. Of course, the app’s name will differ based on which app you open.

If you wish to change the text size on all apps to this value, you can let it be on All Apps.

Step 9: If the new text size is too large or too small, you can go back to the control center and change it accordingly.

You have now successfully changed the text size on an individual app on your iPhone. Repeat the same process from Step 4 onwards for all the required apps.

Use Different Font Sizes on Individual Apps

Feel free to experiment with various font sizes on different apps. Smaller fonts on a vertically scrolling feed make sense if you want to view more content. A larger text size helps to make the content easily readable, especially for senior folks.
