how do you change text size on home screen when accidently made to big on iPhone 14

Hi kprolph

welcome to the Apple (user-to-user) Community.

Wondering if this Apple Support article can help:

How to: Use display and text size preferences on your iPhone, iPad and iPod touch – Apple Support

Eg: says "open the Settings app, then tap Accessibility > Display & Text Size."

You can find these accommodations on the > Display & Text Size screen:

Bold Text: Makes text bold.

Larger Text:

Tap this, then turn on Larger Accessibility Sizes.

Use the slider to choose your preferred reading size.

So you may just need to adjust that slider.

Else:

If the icons on your Home screen appear too large or are magnified to fit the screen, your device may have the Zoom feature turned on.

All the best :-)
