Unable to increase text size on iPhone 18 Pro apps

I have recently upgraded from an iPhone 17Pro ti an iPhone 18Pro.

i have found that the text size on various apps are microscopically small. Especially on having to enter responses on many sites. The text size on my iPhone 17 was much larger. I have tried increasing the size by altering Accessibility settings in Systems menu and pinching / expanding screen, all to no avail. Now running out of options.

Thank you

Hi there


Please try this


If the issue is isolated to specific apps or web browsers, you can force them to display larger text using the Control Center. 

  1. Add the Text Size button to your Control Center:
    • Open the Settings app.
    • Tap on Control Center.
    • Find Text Size (the Aa icon) and tap the green "+" button to add it. 
  1. Adjust the text inside the problem app:
    • Open the app or website where the text is too small.
    • Swipe down from the top-right corner of your screen to open the Control Center.
    • Tap the Text Size (Aa) button.
    • Crucial Step: Look at the bottom of the screen and tap the toggle so it selects "[App Name] Only" instead of "All Apps".
    • Drag the slider up to increase the font percentage (e.g., 120% or 135%).
