Target sizes on the phone: 24×24 pixels as the floor
Controls must measure at least 24×24 pixels, unless they're spaced far enough apart or sit within body text. What's measured is the clickable area, not the icon inside it — a small icon inside a large button is fine.
- Typically affected are toolbars, close icons, row actions in tables, and star ratings. At a desk with a mouse pointer, you hit them reliably; with a thumb, you don't.
- The check measures per device profile, since the same button renders at different sizes depending on the layout, and names examples of undersized areas along with their dimensions.
- This rule is new in WCAG 2.2, and so it affects many existing interfaces that previously counted as fine.
