WCAG Levels
WCAG Level AAA
Enhanced accessibility — 31 additional criteria (86 total: 31 A + 24 AA + 31 AAA). Includes sign language for video (1.2.6), 7:1 contrast (1.4.6), 44×44px targets (2.5.5), and reading level (3.1.5). Aspirational, not achievable for all content. Cherry-pick criteria that benefit your audience.
In plain terms
The highest, strictest level. Worth aiming for in places, but not realistic to meet everywhere.
Why this matters
AAA is the gold standard of access, but it isn't realistic across a whole site. Knowing which AAA criteria to adopt selectively — enhanced contrast, reading level — can meaningfully help your users.
