?What are WCAG Standards?

The Web Content Accessibility Guidelines (WCAG) are the international standard for making web content more accessible to people with disabilities, including those with low vision or color blindness.

A high contrast ratio between text and background ensures that information is easy to read for everyone, including users browsing your site on a mobile device in direct sunlight.

The Rating Scale

AA Standard

The minimum requirement. Requires a ratio of 4.5:1 for normal text and 3:1 for large text (18pt+).

AAA Standard

The gold standard of accessibility. Requires 7:1 for normal text and 4.5:1 for large text.

Normal vs Large

Large text is defined as at least 18pt (24px) or 14pt (18.66px) if the font is bold.

Color Blindness

Using contrast instead of just color helps color-blind users distinguish between elements.

Design Tip

When in doubt, aim for **AA Standard**. While AAA is great for information-heavy sites (like government or healthcare), it can be restrictive for artistic branding. However, never go below AA, as it significantly degrades the experience for users with vision impairments.
