Accessibility Basics for Designers

Category: Inclusive Design | Published: August 2025

Designing for accessibility means creating experiences that work for as many people as possible — including those with disabilities. In today’s digital-first world, accessibility is not optional. It’s a legal, ethical, and business imperative. Good design includes everyone, regardless of ability, device, or context.

Why Accessibility Matters

• ♿ One in four adults lives with a disability
• 📱 Assistive tech users rely on accessible design to navigate digital content
• ⚖️ Laws like ADA, WCAG, and EN 301 549 require digital accessibility
• 💡 Better accessibility leads to better usability for everyone

Key Accessibility Principles

• Perceivable: Users must be able to perceive information (e.g. alt text for images, captions for videos)
• Operable: Interface must be usable with keyboard or screen readers
• Understandable: Content and navigation should be predictable and clear
• Robust: Code must be compatible with various assistive technologies

Design Tips for Accessibility

• Use high color contrast (minimum 4.5:1 for body text)
• Ensure text is resizable without breaking layout
• Use clear, simple language and meaningful headings
• Don’t rely solely on color to convey meaning
• Ensure all interactive elements are focusable and labeled

Common Mistakes to Avoid

• Missing alt text for images
• Low contrast between text and background
• Non-descriptive links (e.g. “Click here”)
• Auto-playing media with no pause option
• Keyboard traps and hidden focus indicators

Tools to Check Accessibility

• WAVE (WebAIM)
• axe DevTools
• Lighthouse (Chrome)
• VoiceOver, NVDA, or TalkBack screen readers

Conclusion

Accessible design isn’t about limiting creativity — it’s about expanding your reach. By embedding accessibility from the start, you create inclusive experiences that empower all users. Start small, test often, and design with empathy. Because accessibility isn’t a feature — it’s a foundation.
