1.4.4: Resize Text

What it means

Text must be readable when users enlarge it up to 200% without assistive technology. Layout should not break so badly that content is clipped or requires horizontal scrolling on a desktop window.

People with low vision often zoom the whole page instead of changing site settings.

How to fix it

• Use relative units (rem, em, %) for text and containers where possible.
• Avoid fixed-height boxes that clip text when font size increases.
• Test at 200% browser zoom on a typical laptop screen width.
• Let long words wrap instead of overflowing hidden containers.

Quick examples

• Good: Body text scales to 200% zoom and paragraphs reflow without loss of content.
• Bad: At 200% zoom, button labels are cut off by fixed-height cards.
• Good: Navigation wraps to a second line instead of hiding menu items.
• Bad: Important disclaimers disappear because overflow is set to hidden.
