Large Text Example
This is small text. Make sure it's readable for users with visual impairments.
Normal text: Text smaller than 18pt (or 14pt bold)
Large text: Text 18pt or larger (or 14pt bold or larger)
WCAG AA: Minimum contrast for legal compliance in most countries
WCAG AAA: Enhanced contrast for better accessibility
Color contrast is the difference in light between text (foreground) and its background. It's measured as a ratio from 1:1 (no contrast, same color) to 21:1 (maximum contrast, like black on white). Higher contrast makes text more readable, especially for people with visual impairments.
WCAG (Web Content Accessibility Guidelines) sets minimum contrast requirements for web accessibility. Meeting these standards ensures your content is readable for everyone, including people with color blindness, low vision, or those viewing content in various lighting conditions.

WCAG (Web Content Accessibility Guidelines) are international standards for web accessibility. WCAG AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. WCAG AAA requires 7:1 for normal text and 4.5:1 for large text.
Normal text is smaller than 18pt (or 14pt bold). Large text is 18pt or larger (or 14pt bold or larger). Large text has lower contrast requirements because it's easier to read even with lower contrast.
Color contrast is essential for accessibility. It ensures text is readable for everyone, including people with visual impairments, color blindness, or those viewing content in bright sunlight. Good contrast also improves readability for all users.
For legal compliance, aim for WCAG AA (4.5:1 for normal text, 3:1 for large text). For better accessibility, aim for WCAG AAA (7:1 for normal text, 4.5:1 for large text). Higher contrast is always better for readability.
