How do I make my apps larger on iPhone 14 pro max?

Greetings brendadlyons,

You can learn how to adjust the display and test size on your iPhone here:

Adjust the display and text size on iPhone - Apple Support

"Adjust the text size when you’re using an app

1. Open Control Center, then tap .
2. (If you don’t see , add it to Control Center—go to Settings  > Control Center, then choose Text Size).
3. Drag the slider up or down to increase or decrease the text size.

To change the text size for all apps, tap All Apps at the bottom of the screen."

Take care.
