In plain English
The AA rule (2.5.8) says tap targets should be at least 24 by 24 pixels. This AAA rule raises that to 44 by 44, the same size Apple and Google recommend in their own design guides. Bigger targets mean fewer mis-taps, especially on phones and for anyone with limited dexterity.
You do not need 44px to be compliant, 24px meets the required level, but 44px is a solid target for a comfortable mobile store.
Who this is for
- People with motor or dexterity differences, who struggle to hit small targets.
- Everyone on a phone, tapping with a thumb on a moving train.
How to check and fix it yourself
Look at your smallest interactive things: quantity steppers, close buttons, icon links, footer links. If any are smaller than 44px, grow the tappable area with padding (the icon can stay small).
.icon-button,
.qty-button,
.close {
min-width: 44px;
min-height: 44px;
}Where we can help
We measure the tappable area of your controls on a real mobile viewport and flag anything under 44px, noting which also miss the required 24px. Small tap targets are a frequent mobile finding and one of the WCAG 2.1/2.2 checks.
