WCAG 2 criterion
1.4.4 Resize Text (Level AA)
Tools and requirements
- Web browser with built-in zoom text only feature (Firefox, Safari)
- Zoom Text Only plugin for Chrome
Test procedure
There are two ways to test zooming text to 200%. Only one of the two methods must meet both verification checks to pass.
Zooming the entire page
Use the standard keyboard shortcuts of ⌘= (Command + Equals) or CTRL= (Control + Equals) to zoom the entire page.
Zoom text only
- Firefox
- In the menu bar, select View > Zoom > Zoom Text Only
- Safari
- Use the shortcut ⌥⌘= (Option + Command + Equals)
- Chrome or Edge
- Use an extension such as Zoom Text Only or Text Zoom from the Chrome Web Store
Verification Steps
- Check Scaling: The text must appreciably scale when testing. It must not be locked to a fixed size when scaling the page.
- Check for Clipped or Overlapping Text: No content should clip (be "cut off" by another element), or overlap other elements when zoomed.
