In prior versions of iOS, users were able to adjust the font size for specific core apps through the Accessibility menu. Those apps were Mail, Contacts, Calendar, Messages, and Notes. Sure, this was helpful to those who had trouble seeing the default text size on an iOS device, but outside of those apps it was of no help.
With iOS 7, users can change the default size of text across the entire device, so long as developers have properly updated their apps to support the latest APIs found in iOS 7.
To change the size of Dynamic Text (its technical name), launch the Settings app and then select “General” followed by “Text Size.”
You’ll see a slider with some sample text just above it. Reposition the dial to increase or decrease the font size, using the sample text as an example of the font size you’ve adjusted to. When you’re happy with the size, exit the Settings app.
