Accessibility Contrast Checker

Ensure your website is accessible to everyone by checking color contrast against WCAG 2.1 guidelines. Meet AA and AAA standards for better readability.

Contrast Ratio 4.50:1
Text Color
Background Color
AA Normal Text (4.5:1) PASS
AA Large Text (3:1) PASS
AAA Normal Text (7:1) PASS
AAA Large Text (4.5:1) PASS
Abc - Headline Text
This is a sample of how your text colors will look in a real-world scenario. Accessibility is not just a feature; it's about making the digital world inclusive for everyone. Good contrast prevents eye strain and helps users with visual impairments.

Understand WCAG Standards

WCAG (Web Content Accessibility Guidelines) defines three levels of conformance: A, AA, and AAA.

  • Level AA: The standard requirement for most websites. Requires a ratio of at least 4.5:1 for normal text and 3:1 for large text.
  • Level AAA: The highest level of accessibility. Requires a ratio of at least 7:1 for normal text and 4.5:1 for large text.

Why Color Contrast Matters?

Color contrast is the difference in light between any two colors. In web accessibility, we focus on the contrast between the text (foreground) and the container it sits in (background).

Low contrast can make it impossible for users with color blindness, low vision, or even users in bright sunlight to read your content. By following WCAG standards, you ensure a better experience for **everyone**.

What is "Large Text"?

According to WCAG, large text is defined as:

  • At least 18pt (approx. 24px) for normal weight.
  • At least 14pt (approx. 18.67px) for bold weight.

Large text is easier to read, so it requires a lower contrast ratio (3:1 for AA) than standard body text.

How to use this tool

  1. Enter your text color and background color using the hex input or color picker.
  2. The tool will automatically calculate the ratio and tell you if it passes the **AA** or **AAA** standards.
  3. If your colors fail, check the "Smart Suggestions" area (it appears automatically) to find accessible alternatives that are close to your original choice.
