Level AA · WCAG 2.1

1.4.12 Text Spacing

Users can override line height, paragraph spacing, letter spacing and word spacing without content being cut off or overlapping.

Partly automated Some failures are detectable, others need judgement.

How it fails in practice

A card with a fixed height where increased line spacing pushes the last line behind the card’s footer.

How to fix it

Use min-height instead of height anywhere text lives, and stop setting line-height in pixels.

Partly automated

How far an automated check gets

A tool finds some failures here and cannot see the rest. A clean automated result means the checks that exist found nothing — not that the criterion is met. This is the gap that makes a green scan look like an accessible site, and it is where our agents and a human reviewer do the remaining work.

Find out which criteria your site fails

We scan up to 100 pages against WCAG 2.2 AA, run the agent protocol on one key journey and send you the report — free, once, no strings.
