If you find yourself squinting at your iPhone screen, holding the phone at arm's length, or struggling to read small menu text — you are not alone, and you do not have to put up with it. iPhone has several built-in settings that make text and the whole display bigger and easier to see.

These settings are free, built in, and completely reversible. You can turn them up and down as much as you like.

The three main things you can change are: 1. **Text size** — makes all text in apps and menus larger 2. **Bold text** — makes all text darker and heavier, easier to read 3. **Display Zoom** — makes everything on screen bigger, including app icons, buttons, and images

There is also a feature called "Larger Accessibility Sizes" that lets you go even bigger than the normal slider allows. If standard Large text is still not big enough, this unlocks extra-large sizes.

These settings apply across your entire iPhone — not just one app. Once you set them, every app, every menu, and every notification will use the larger text.
