How to Make Text Bigger on ANY Device (Without Breaking Everything)

I can always tell when a grandchild has visited: suddenly the text is tiny or enormous!

Here are the three buttons you need to know:

iPhone/iPad
Settings → Display & Brightness → Text Size → drag the slider

Android phone/tablet
Settings → Display → Font size (or Display size) → move the slider

Windows laptop
Right-click desktop → Display settings → Scale → try 125% or 150%

Bonus: on iPhone you can triple-click the side button to toggle a temporary zoom if you’re stuck in a tiny menu.

I keep a little cheat-sheet magnet on my fridge with these steps. Works every time.
