Contrast Ratio
WCAG (Web Content Accessibility Guidelines) by W3C ensures web content is accessible to people with disabilities. Our contrast checker helps verify compliance.
WCAG AA requires 4.5:1 contrast for normal text and 3:1 for large text (18pt+). This is the minimum recommended standard for most websites.
WCAG AAA requires 7:1 for normal text and 4.5:1 for large text. Use this for enhanced accessibility in critical information.
Large text is defined as 18pt (24px) regular or 14pt (18.66px) bold. Large text has lower contrast requirements due to better visibility.
