How to Use This Calculator
  1. Enter Contrast Ratio — use a color contrast checker tool to find the ratio between your text and background colors.
  2. Set Text Size (pt) — text 18pt or larger (or 14pt bold) qualifies as large text with relaxed contrast requirements (3:1 instead of 4.5:1).
  3. Set Has Alt Text to 1 if all meaningful images have descriptive alt attributes in your HTML.
  4. Set Keyboard Navigable to 1 if all interactive elements (buttons, links, forms) are operable without a mouse.
  5. Set ARIA Labels to 1 if dynamic content regions use proper ARIA roles and labels.
  6. Review Compliance Score (%) and WCAG Level — aim for Level AA (score ~80%) for legal compliance in most jurisdictions.
