Frequently asked questions
Is WCAG 2.2 required everywhere?
Requirements vary by law, contract, and organization. WCAG 2.2 is the current W3C recommendation, while some rules and policies specifically reference WCAG 2.1 AA.
Should I target WCAG 2.1 or WCAG 2.2?
Many teams use WCAG 2.1 AA as a legal baseline where referenced, then adopt WCAG 2.2 practices because they improve current usability and future readiness.
