How to Increase Text Size on an iPhone

By Laurie Reeves

When reading text on your iPhone makes you feel as if you need a magnifying glass just to see the letters, a few quick taps and finger swipes can fix the problem in seconds. The iPhone's user interface is one of its most user-friendly areas, allowing you to change your phone's settings with a few taps and swipes. Phones with iOS 7 offer two ways to change the text size.

Font Size

Step 1

Navigate to the "Settings" icon on your iPhone. The icon resembles a series of different sized gears and is usually found on the home screen of your iPhone.

Step 2

Tap the "Settings" icon and select "General."

Step 3

Look for the "Text Size" option and tap it to open the screen. Swipe the slider to the desired text size.

Dynamic Larger Type

Step 1

Access the "Settings" icon on the iPhone's home screen and then select "General."

Step 2

Navigate down the screen and tap on "Accessibility" and then "Larger Text."

Step 3

Turn on the option for "Larger Accessibility Size," which increases the maximum size on the text-size slider. Swipe the slider. The text size increases as you move your finger across the slider to the right.

Tips & Warnings

  • You can also change the font to bold, inverse colors or increase contrast from the "Accessibility" screen on iPhones with iOS 7.
  • On older iPhones, you can access font size after tapping "Accessibility." Scroll down until you find the text size that works for you. Each text depicts the size as it appears on your screen. Choose from one of several font sizes ranging from 20 point text all the way to 56 point text. Tap on the desired text size to change it.
  • Apple's dynamic larger type option does not work with apps that do not support it.
