WCAG Contrast checker


WCAG 2.0 level AA requires a contrast ratio of 4.5:1 for normal text and 3:1 for large text (14 point and bold or larger, or 18 point or larger).

This tool helps you to achieve the target contrast ratios in text and non-decorative images.

What it does

Your website is analyzed - text spans within the target contrast limit are highlighted with a green box, outside the target with a red box. The box is captioned with the calculated contrast ratio.

OK, let's go
