What is a good font size for mobile?
A good starting point for mobile body text is 16px. It’s readable on most screens and accessible for most users.
Headings: Scale up based on importance (e.g., 24–32px for H1).
Don’t go too small: Anything under 14px becomes hard to read.
Test on device: Always preview fonts in real app conditions.
