WCAG 2.2 AA – Quick Checklist
Use this checklist as a final verification step when implementing or reviewing user interfaces. The checklist helps ensure that accessibility requirements defined in this stylebook have been met before release.
Keyboard navigation
- All functionality is operable using a keyboard only.
- Interactive elements are reachable using the keyboard (Tab key).
- Focus order follows a logical reading order.
- No keyboard traps are present.
Focus and interaction
- Focus indicators are always visible.
- Focus is not removed or suppressed.
- Focus remains visible against all backgrounds.
- Hover effects are not the only indicator of interactivity.
Contrast and color
- Text has a minimum contrast ratio of 4.5:1 against its background.
- Large text meets a minimum contrast ratio of 3:1.
- Non-text UI elements (borders, icons, focus indicators) have a minimum contrast ratio of 3:1.
- Color is not the only means of conveying information.
Touch targets
- Interactive elements meet minimum touch target size requirements defined by WCAG.
- Small visual elements have sufficient interactive hit areas.
Text and content
- All form fields have visible labels.
- Placeholder text is not used as the only label.
- Text remains readable when resized.
Text resizing and scaling
- Text can be resized up to 200% without loss of content or functionality.
- Layout adapts when text is resized and does not cause content overlap or clipping.
- Text resizing does not introduce horizontal scrolling on common viewport widths.
- Relative units (such as rem) are used to support user-controlled text scaling.
Icons and imagery
- Icons do not replace text for critical information.
- Decorative icons are hidden from assistive technology.
- Interactive icons are keyboard accessible and focusable.
States and feedback
- Selected, disabled, and error states are clearly distinguishable.
- Error messages are communicated using text in addition to visual styling.
- Status changes are not conveyed by color alone.
Consistency and predictability
- Interaction patterns are consistent across components.
- Navigation and behavior are predictable.
