WCAG Contrast Checker

Pick two colors. We compute the contrast ratio and check WCAG 2.1 AA & AAA pass-fail at every text size.

The quick brown fox jumps over the lazy dog. Smaller body text for AA-small judgment.

Contrast ratio17.53:1
  • AA Normal text (≥ 4.5:1) Pass · ≥4.5
  • AA Large text (≥ 3:1) Pass · ≥3
  • AAA Normal text (≥ 7:1) Pass · ≥7
  • AAA Large text (≥ 4.5:1) Pass · ≥4.5
  • UI components & icons (≥ 3:1) Pass · ≥3

Large = 18pt+ (24px) or 14pt+ bold (18.66px+). Anything else is "normal".
