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

  1. 01Size text and containers with relative units so they grow together.
  2. 02Avoid fixed heights on text containers; let them expand.
  3. 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.
