Additional Information

But wait, there’s more! Did you know that iOS 17 also allows you to make the text bold, in addition to making it bigger? That’s right, if you head back to Display & Brightness settings, right under Text Size, there’s an option to turn on Bold Text. This can further enhance readability, especially in bright light conditions or if you just crave that extra punch of boldness.

What’s more, if you need even larger text for specific apps, iOS 17 has got you covered with the Accessibility settings. Just go to Settings, then Accessibility, and tap on Display & Text Size. Here you’ll find the Larger Text option, which unlocks even bigger font sizes.

And remember, while most apps will respect the new font size you’ve set, some might not. This is because certain apps manage their own font settings. But don’t fret; many popular apps have an in-app setting to adjust text size, so be sure to check the app’s settings if you need an extra boost in size.
