How to Make Text Bigger and Easier to Read on iPhone

Reaching for your glasses every time you check a message? Or holding your phone at arm's length?

Your iPhone can make text bigger and bolder across the whole phone. It takes a few seconds and makes a real difference.

Text Size makes text bigger in apps that support Dynamic Type, which includes most Apple apps and many others. Bold Text makes letters thicker and easier to read. Display Zoom goes further and makes everything on screen bigger, including icons and buttons.
