A11Y: Fundamentals of Designing Inclusive Interfaces

May 5, 2025 1 min read 53 People Read

Accessibility (A11Y) ensures your digital products can be used by everyone. Here are the fundamental principles:

Fundamental accessibility principles:

  • Color Contrast: At least 4.5:1 contrast ratio between text and background (WCAG AA)
  • Keyboard Navigation: All functions should be accessible via keyboard, with visual focus indicators
  • Screen Reader Compatibility: Use semantic HTML, alt texts, ARIA labels
  • Text Size: Avoid fonts smaller than 16px, should be scalable
  • Motion and Timing: Allow control over animations, provide sufficient time
  • Form Access: Clear labels, error messages, autocompletion

Accessibility provides better experiences not just for disabled users, but for everyone. Plus, there are legal requirements such as ADA in the US and EAA in Europe.

Inclusive design helps you reach a wider audience.
