Small lettering can make everyday reading on an iPhone or iPad tiring. Text Size makes the font larger or smaller in Settings and other supported apps.
Apps that support Apple's Dynamic Type follow your preferred reading size. Text may wrap onto more lines as it grows, so less content fits onscreen at once. Some apps and web pages use their own text sizing and may not respond to this setting.
The Larger Text accessibility setting includes the standard sizes and an extended range for readers who need bigger letters. Display Zoom changes the size of icons and controls as well, making it a better fit when the whole interface feels too small.
Steps to adjust text size on iPhone and iPad:
- Open Settings.
- Tap Accessibility.
On iPad, Accessibility appears in the Settings sidebar. For the standard size range alone, iOS 27 and iPadOS 27 also provide Settings > Appearance > Text Size. On iOS 26 and iPadOS 26, that control is under Display & Brightness. The accessibility route here includes the extra-large sizes.
- Tap Display & Text Size.
- Tap Larger Text.
- Enable Larger Accessibility Sizes if you need extra-large text.
- Drag the slider right for larger text or left for smaller text.
The preview text changes as you adjust the slider, and the size takes effect without a Save button.
- Tap the back arrow to return to Display & Text Size.
- Check that the Settings labels now use your chosen text size.
The enlarged labels shown here confirm a larger selection; a smaller selection should shrink the text instead. An app or web page that does not support this preference may keep its previous text size.
