WCAG 2.2 Web Accessibility
Definition and European Legal Standards
WCAG 2.2 Web Accessibility is the international technical standard published by the W3C that defines how to make web content perceivable, operable, understandable, and assistive-technology compatible, serving as the compliance benchmark for the European Accessibility Act (EAA) across €4,500 to €9,000 corporate websites.
Our UX/UI design and engineering teams bake WCAG 2.2 Level AA directly into component tokens. Read our complete guide to accessible website design.
Core Engineering Requirements (POUR)
Achieving WCAG 2.2 Level AA requires a minimum 4.5:1 text contrast ratio, full keyboard navigation with visible focus rings, 24x24px minimum target sizes, semantic landmark HTML, and descriptive ARIA/alt attributes across all forms and web portals.
Follow our complete EAA 2026 accessibility checklist and embed accessible primitives into your design system. Verify EN 301 549 readiness before regulatory deadlines with a full WCAG 2.2 AA accessibility audit.
