Accessibility Statement

Last updated: February 1, 2026

Our commitment

CalcRegistry is committed to making its calculators, converters, and reference tools accessible to the widest possible audience, regardless of ability or technology. We aim to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 at the AA level.

Accessibility features

  • Semantic HTML — Pages use proper heading hierarchy, landmarks, labels, and ARIA attributes so screen readers can navigate content meaningfully.
  • Keyboard navigation — All interactive elements (inputs, dropdowns, buttons, toggles) are reachable and operable via keyboard alone.
  • Form labels — Every input field and select element has an associated label (visible or screen-reader-only) to identify its purpose.
  • Responsive design — Layouts adapt to screen sizes from mobile phones to large monitors, and content reflows without horizontal scrolling at up to 400% zoom.
  • Color contrast — Text and interactive elements meet WCAG AA contrast ratios against their backgrounds.
  • Focus indicators — Interactive elements display visible focus rings for keyboard users.
  • No auto-play — The site does not auto-play audio or video content.

Known limitations

We are aware of the following areas where accessibility could be improved:

  • Red Light Mode — The red-light theme on some photography calculators uses low-contrast colors by design (to preserve night vision). Screen readers will still announce all content normally, but visual contrast is intentionally reduced in this mode.
  • KaTeX formulas — Mathematical formulas rendered with KaTeX may not be fully accessible to all screen readers. Where possible, equivalent plain-text descriptions appear nearby.
  • Complex interactive widgets — Some calculators with dynamic filter stacks or multi-field time pickers may present navigation challenges for certain assistive technologies. We are working to improve these.

Browser and assistive technology compatibility

CalcRegistry is designed to work with current versions of major browsers (Chrome, Firefox, Safari, Edge) and common screen readers (NVDA, JAWS, VoiceOver). If you encounter issues with a specific browser or assistive technology combination, please let us know.

Feedback

We welcome feedback on the accessibility of CalcRegistry. If you encounter a barrier or have a suggestion, please reach out through our Contact Us page. We will make reasonable efforts to address reported issues promptly.
