Accessibility Statement
Last updated
We aim for every calculator to be usable by everyone, conforming to WCAG 2.2 level AA.
What we've done
- All inputs have visible labels with units; errors are announced and shown next to the field.
- Results update in a polite live region so screen readers announce new totals.
- Everything works with a keyboard; focus is always visible; touch targets are at least 44 × 44 px.
- Diagrams have text alternatives; color is never the only way information is shown.
- Light and dark themes are contrast-checked; animations respect “reduce motion”.
- Pages reflow to 320 px wide without horizontal scrolling; tables become cards on small screens.
Known limitations
We have run automated checks (Lighthouse/axe). Manual testing with VoiceOver and NVDA is scheduled before public launch.
