WCAG 2.2 AA checklist — an accessibility checklist

Updated: 2026-06-16

A concise, practical checklist of the most important WCAG 2.2 level AA criteria — where to start to meet EAA requirements.

The four WCAG principles (POUR)

WCAG organises every criterion around four principles: Perceivable, Operable, Understandable and Robust.

Level AA is the threshold required by the EAA through the EN 301 549 standard — it is the reference point for an audit.

Perceivable content and contrast

Ensure a text contrast of at least 4.5:1 (3:1 for large text), alternative text for meaningful images, and captions for video recordings.

Never convey information by colour alone — add a label, icon or pattern.

Keyboard operation and focus

All functionality must work from the keyboard, with no focus traps, and the focus indicator must be visible.

WCAG 2.2 adds, among others, that a focused element must not be fully hidden (Focus Not Obscured) and that accessible alternatives to dragging gestures are provided (Dragging Movements).

Forms, headings and target size

Every form field needs an associated label, and error messages must identify the field and how to fix it. The heading structure (h1–h6) should be logical.

WCAG 2.2 introduces a minimum touch target size (Target Size, 24×24 px) — important on mobile devices.

How to check your site

An automated scan catches a large share of issues (contrast, missing labels, element names), but some criteria require manual review. EAAsy combines the scan with prioritisation by sanction risk, so you know what to fix first.
