Accessibility
Last updated: March 2026
CalcRun is designed to be usable by everyone, including people who use assistive technology. We test continuously and fix issues as we find them.
Our Standard
We aim to meet WCAG 2.1 Level AA across all pages. Every commit is tested against axe-core automated accessibility checks covering contrast, structure, keyboard access, and ARIA usage.
Keyboard Navigation
Every calculator, tool, and interactive element on CalcRun is fully operable using a keyboard. Tab moves between controls, Enter and Space activate buttons, and Escape closes dropdowns and menus. All focused elements show a visible focus ring.
Colour & Contrast
All text meets a minimum contrast ratio of 4.5:1 against its background. CalcRun supports both light and dark modes, and both are tested for WCAG AA compliance. The site respects your system colour scheme preference.
Screen Readers
Pages use semantic HTML (headings, landmarks, lists, labels). Decorative icons are hidden from assistive technology. Calculator results are announced via aria-live regions so they update without requiring a page reload.
Motion & Animation
All animations respect the prefers-reduced-motion system setting. If you have reduced motion enabled, animations are disabled site-wide.
Responsive Design
CalcRun works across screen sizes from 320px to ultrawide. Text inputs are at least 16px to prevent auto-zoom on iOS. Touch targets meet minimum size recommendations.
Known Limitations
Some interactive charts (powered by Recharts) may not fully convey data to screen reader users. We provide the same information as tabular data alongside every chart. If you encounter an accessibility issue we have missed, please let us know.
Feedback
If you experience any difficulty using CalcRun, or have suggestions for improving accessibility, contact us at hello@calcrun.com. We take accessibility reports seriously and aim to respond within 7 days.
