This is how normal text looks. Web accessibility is important for reaching the widest possible audience. Ensure your contrast ratio is at least 4.5:1 for normal text and 3.0:1 for large text.
Understanding WCAG Contrast Guidelines
Web Content Accessibility Guidelines (WCAG) define specific contrast ratios to ensure content is readable by people with moderately low vision.
AA vs AAA Compliance
AA level is the industry standard, requiring a contrast ratio of 4.5:1 for normal text and 3:1 for large text. AAA level is the gold standard, requiring 7:1 for normal text and 4.5:1 for large text.
Why It Matters
Poor contrast makes reading difficult for everyone, especially in glaring sunlight or for users with visual impairments. Meeting WCAG standards not only improves user experience but is also a legal requirement in many jurisdictions.
