Touch Target Size

Touch target size is the area a person can tap to activate a button, link, or other on-screen control. Targets that are tiny or crowded together can cause accidental taps, especially for people with limited dexterity. A lawn care website's 'Call' button should be easy to activate without hitting an adjacent menu icon. WCAG 2.2's Target Size (Minimum) criterion generally uses 24 by 24 CSS pixels, with important exceptions for adequate spacing and certain kinds of controls. That is a minimum accessibility test, not a recommendation to make every interface element exactly that size. Comfortable touch design also considers context, placement, and user needs.
