Understanding WCAG Standards

Level AA

The legal standard for most websites. Requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text.

Level AAA

The gold standard for accessibility. Requires 7:1 for normal text and 4.5:1 for large text. Best for sites serving users with low vision.
