Understanding WCAG Standards

Web Content Accessibility Guidelines (WCAG) ensure content is accessible to people with disabilities.

Contrast ratio requirements:

  • AA (Minimum): 4.5:1 for normal text, 3:1 for large text (18pt+ or 14pt bold)
  • AAA (Enhanced): 7:1 for normal text, 4.5:1 for large text

This tool helps you meet these important accessibility standards.

Why Accessibility Matters

Proper color contrast is essential for:

  • Users with visual impairments
  • People with color blindness (affects 1 in 12 men)
  • Older users with diminished eyesight
  • Mobile device users in bright sunlight
  • Anyone using low-quality displays

Good contrast improves readability for all users and is required by accessibility laws worldwide.
