WCAG

Web Content Accessibility Guidelines

WCAG are internationally recognized standards developed by the World Wide Web Consortium (W3C).

They define how websites and digital content should be designed and coded so individuals with a range of disabilities — visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities — can use them effectively.

The guidelines benefit people with disabilities, but also improves usability for all users, including older individuals and those using different devices.

Success criterion 2.2.5: Target size

WCAG is divided into numerous individual success criterion. Each criterion is a specific, testable requirement defined under WCAG.

Success criteria (SC) are organized into three levels of conformance: A (minimum), AA (mid-range), and AAA (highest). The criteria allow for objective testing and are used in design specifications, regulations, and contracts to measure and enforce accessibility

Success Criterion 2.5.5 is Target Size:

  • Goal: Make controls easier to operate, especially on touch screens

  • Requirement: Make targets at least 44 by 44 pixels

  • Why it’s important: Some people cannot tap small objects

The criterion makes tap selections easier for users by making the targets for intended taps bigger.

How KLOA helps

KLOA’s tap targets exceed the requirement for WCAG 2.5.5.

For a iPhone 16 mobile phone (screen width = 2.8”), the target size for each selection button is 53 x 53 pixels. In comparison, for the standard QWERTY keyboard on the same size screen, targets are just 27 x 38 pixels.

For a standard-size phone screen, KLOA exceeds the WCAG 2.5.5 success criterion by 20%.
