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.
