Font Size

Checks for readable font sizes on mobile

Rule ID	mobile/font-size
Category	Mobile
Scope	Per-page
Severity	warning
Weight	4/10

Solution

Body text should be at least 16px for readability without zooming. Smaller fonts strain eyes on mobile. Use relative units (rem, em) for scalability. Test on actual devices. Google’s mobile-friendly test flags font sizes under 12px. Line height should be at least 1.5 for readability.
