WCAG 1.4.4 · Level AA
Does my design survive 200% text zoom?
Text must scale to 200% without loss of content or function (WCAG 1.4.4, AA), and stay readable when users override line height and letter spacing (1.4.12). Use relative units and avoid fixed-height containers that clip growing text.
What it is
Text resize covers zooming text to 200% and applying user spacing overrides without breaking the layout.
Why it matters
Many low-vision users enlarge text. Fixed pixel containers clip it; cramped line height makes it unreadable.
How to fix it
- 01Size text and containers with relative units so they grow together.
- 02Avoid fixed heights on text containers; let them expand.
- 03Leave room for increased line height and letter spacing.
How Aulys catches it
Aulys checks that text containers in your design can absorb 200% scaling and spacing overrides without clipping.
