Text Color Accessibility Checker

Test your text and background colors against WCAG 2.1 accessibility standards.

About Text Color Accessibility

Our Text Color Accessibility Checker helps you ensure your color combinations meet WCAG 2.1 guidelines for readable text. It calculates the contrast ratio between your text color and background color, then checks against AA and AAA compliance levels.

Accessible color contrast is essential for users with visual impairments, users in bright environments, and anyone reading text on screens. Many accessibility laws require WCAG compliance for websites and applications.

Frequently Asked Questions

What is WCAG?

WCAG (Web Content Accessibility Guidelines) is an international standard for making web content accessible to people with disabilities. It defines specific contrast ratio requirements for text.

What contrast ratio is required?

AA level requires 4.5:1 for normal text and 3:1 for large text (18px+ or 14px bold). AAA level requires 7:1 for normal text and 4.5:1 for large text.

What counts as "large text"?

Large text is defined as 18pt (24px) or larger, or 14pt (18.5px) bold or larger. Large text has lower contrast requirements because it's easier to read.

Is WCAG compliance legally required?

In many countries and industries, yes. The EU Web Accessibility Directive, Section 508 (US), and various other regulations require WCAG compliance for government and public-facing websites.
