WCAG AA requires a contrast ratio of at least 4.5:1 for normal text (1:1 for large text). AAA requires 7:1 for normal text (4.5:1 for large text). AAA is the higher accessibility standard.
Large text is 18pt+ or 14pt+ bold. Small text (under 18pt normal weight) requires higher contrast ratios for WCAG compliance.
We use the W3C formula: (L1 + 0.05) / (L2 + 0.05), where L is the relative luminance of the lighter color. This gives ratios from 1:1 (no contrast) to 21:1 (maximum contrast).
Low contrast makes text hard to read for people with color blindness, low vision, or when viewing on poor displays. High contrast improves readability for everyone.
Yes. A ratio of 4.8:1 meets AA but not AAA (which requires 7:1). AAA is the stricter standard.
Increase the contrast by making text darker or background lighter (or both). Use the contrast checker to test modifications until you pass your target standard.
