WCAG 1.4.12 Text Spacing
Level AA
Users must be able to override line height (≥1.5×), paragraph spacing (≥2× font size), letter spacing (≥0.12×), and word spacing (≥0.16×) without losing content or functionality.
Common failures
- Fixed-height containers clip text when users apply spacing overrides.
- Inline truncation hides content rather than allowing wrap.
How to fix
- Use `min-height` instead of `height` on text containers.
- Test with the WCAG text-spacing bookmarklet or DevTools overrides.
