Contrast Checker: Design for Everyone

Check color contrast ratios against WCAG 2.1 standards. Ensure your web content is accessible and readable for all users.

The Necessity of Inclusive Design

Accessibility is a fundamental pillar of modern web design. Ensuring text has sufficient contrast is not just about aesthetics—it's about ensuring content is readable for everyone, including those with color blindness.

WCAG Standards Explained

  • Level AA (Minimum): Requires a ratio of 4.5:1 for normal text. This is the legal requirement for most commercial sites.
  • Level AAA (Gold Standard): Requires a ratio of 7:1. Achieving this provides the best experience for the widest range of users.
  • Large Text: Headings over 24px (or 18pt bold) require lower ratios (3:1 for AA) as they are inherently easier to read.

UI/UX Best Practices

Don't just check default states. Ensure hover, active, and focus states also meet requirements. High contrast also improves usability in direct sunlight or on low-quality monitors.
