User Agent Control

The size of the target is determined by the user agent and is not modified by the author;

Essential

A particular presentation of the target is essential to the information being conveyed.

Guidance:
Techniques: WCAG currently only includes the following undocumented techniques for this success criterion:
  • Ensuring that touch targets are at least 44 by 44 CSS pixels.
  • Providing a mechanism to change the size of the target independent of magnification.

Purpose

The purpose of this success criterion is to aid users who lack the ability or dexterity to activate small targets with a pointer device.

It differs from 2.5.8 primarily in having a larger minimum size for the target area.

How to Meet

Except for the cases listed in the success criterion text, authors need to ensure that all target areas (buttons, etc.) are at least 44 pixels by 44 pixels in dimensions
