How to Change the Font on iPhone

Enlarging and Bolding Text

Understand the limitations. As per your iPhone's built-in settings, you can decrease or increase text size and bold (or un-bold) text. Because your iPhone's apps and Home screen use a uniform design, adjusting the text size and weight is the only legitimate way to change your iPhone's font. If you want to customize your iPhone to make it more personal, you can experiment with custom icons, Home screen layouts, and widgets.

Open your iPhone's iPhone Settings App Icon Settings. Tap the Settings app icon, which resembles a set of gears on a grey box.

Scroll down and tap Display & Brightness. This will show your display settings, including text size. You can find this underneath General and Control Center.

Tap Text Size. It's towards the bottom of the screen. This will open a new page with a slider.

Drag the slider to adjust the text size. You can drag it left to make the text smaller or right to make the text bigger than the default size. The text on the screen will change sizes as a preview. This adjustment will affect all iOS apps that support Dynamic Type. If the app does not support Dynamic Type, the font size will not change from its default. This setting will also change your iOS Mail font.

Tap the "Back" button. It's in the top-left corner of the screen. Doing so will save your changes; you'll see your chosen text size applied to the Settings app immediately.

Tap the white "Bold Text" switch iPhone Switch Off Icon if you want to enable bold text. This will apply your changes immediately. If your iPhone's text is already bold, this switch will be green. Tapping it will remove the bold effect from your iPhone and turn the switch grey.

Changing Accessibility Settings

Open your iPhone's iPhone Settings App Icon Settings. Tap the Settings app icon, which resembles a set of gears on a grey box.

Scroll down and tap Accessibility. You'll find it near the middle of the screen.

Click Display & Text Size.

Tap Larger Text. This can be found at the top of the page. Doing so will open a screen similar to the Text Size menu found in the previous method. If you can't find this option, confirm your iPhone is updated.

Tap the greyed out "Larger Accessibility Sizes" switch iPhone Switch Off Icon to turn it on iPhone Switch On Icon. The slider below it will expand to show additional size options.

Enlarge your iPhone's text. Drag the slider to the right to see the largest text sizes possible. This size change will only apply to apps that support Dynamic Type and the larger Accessibility sizes.
