WCAG 2.1 vs WCAG 2.2: What Changed

Evolution of Accessibility Standards

The Web Content Accessibility Guidelines continue to evolve to address new technologies and user needs. WCAG 2.2, released in 2023, builds upon WCAG 2.1 while maintaining backward compatibility.

Key Additions in WCAG 2.2

WCAG 2.2 introduced new success criteria including focus not obscured, dragging movements, target size, and consistent help. These additions address common accessibility barriers in modern web applications.

Color Contrast Requirements

Color contrast requirements remain unchanged between WCAG 2.1 and 2.2. The minimum ratios of 4.5:1 for normal text (AA) and 7:1 for enhanced accessibility (AAA) continue to be the standard.

Migration Considerations

If your site already meets WCAG 2.1 Level AA, you're well-positioned for WCAG 2.2 compliance. Review the new success criteria and update your accessibility testing procedures accordingly.
