Calculate the contrast ratio of text and background colors. This page provides free color contrast analysis tools that will display the color contrast issues of a web page or chosen color-pair; per WCAG 2.1 guidelines.

Our page offers a handy tool for calculating the contrast ratio between text and background colors. It helps identify any potential color contrast issues on web pages or chosen color combinations, following the WCAG 2.1 Guidelines. Color contrast refers to how colors appear against each other on screens, specifically in terms of their relative luminosity perceived by the human eye. The color contrast checker tool adheres to the Web Content Accessibility Guidelines (WCAG), a set of recommendations aimed at improving web accessibility. These guidelines establish two levels of contrast ratio: AA (minimum contrast) and AAA (enhanced contrast). For the level AA, normal text should have a contrast ratio of at least 4.5:1, while large text (at least 18pt) or bold text should have a ratio of 3:1. For the level AAA, normal text requires a contrast ratio of at least 7:1, and large text or bold text should have a ratio of 4.5:1. Don't let color contrast issues go unnoticed. Use our tool to ensure your web content meets accessibility standards.
