Increase Text Size

Enlarges text on the screen to make it easier to read.

What does this setting do?

Increasing text size helps users who struggle with small or dense text. All major operating systems provide options to enlarge text, though they differ in how the adjustment is applied, from true dynamic text scaling (iOS) to broader display scaling (macOS, Windows, Android). For many people, increasing text size is one of the simplest and most effective accessibility adjustments.

Instructions for different systems

Version: iOS 15+

Open Settings > Accessibility > Display & Text Size > Larger Text. Turn on Larger Accessibility Sizes. Move the slider to the right to select the desired text size.

Additionally, you can enable Button Shapes under Settings > Accessibility > Display & Text Size to make tappable text and buttons more visually distinct.

Note: Not all apps fully support very large text sizes.

Version: varies by device

Open Settings > Display > Display size and text. Increase the Font size. Optionally, you can also increase the Display size to make interface elements larger overall.

Note: Labels and menu paths may vary slightly depending on the device.

Version: Windows 10/11

Open Settings > Accessibility > Text size. Adjust the text size to make text larger across Windows and supported apps.

You can also scale the entire display (text, apps, and other items) under Settings > System > Display in the Scale & layout section.

Note: Some older applications may not fully support text size adjustments.

Version: macOS Ventura/Sonoma

Open System Settings > Display. Under “Scaled”, choose a larger text option such as “Larger Text”. Note: macOS increases overall UI scale, not only text.
