Why EPUB3 WCAG Accessibility Matters

Not everyone reads eBooks the same way. Some people use screen readers, large text, or keyboard navigation. If an EPUB3 file isn’t accessible, these readers can’t use it properly.
Making EPUB3 books accessible means:

  • More people can read your content
  • It follows legal rules (like ADA in the U.S.)
  • Better experience for all readers

Key EPUB3 Accessibility Techniques

  1. Semantic Structure & Proper Heading Hierarchy
    • Use <h1> to <h6> tags to define a logical reading order.
    • Ensure proper nesting for screen readers to navigate efficiently.
  2. Alternative Text for Images & Media
    • Provide descriptive alt text for images, charts, and graphs.
    • Include captions and transcripts for audio and video content.
  3. Keyboard Navigation & Focus Management
    • Ensure all interactive elements (links, buttons) are keyboard-operable.
    • Avoid keyboard traps that prevent users from navigating freely.
  4. ARIA (Accessible Rich Internet Applications) Landmarks
    • Use ARIA roles (role="navigation", role="main") to improve screen reader comprehension.
    • Label interactive elements clearly with aria-label or aria-labelledby.
  5. Text-to-Speech (TTS) Compatibility
    • Use high-contrast colors and readable fonts.
    • Avoid justified text, which can disrupt readability for dyslexic users.
  6. EPUB3 Metadata for Accessibility
    • Include accessibility metadata in the EPUB package file (<metadata>).
    • Declare features like accessMode="textual" or accessibilityFeature="alternativeText".

Why is EPUB3 WCAG Compliance Important?

  • Future-Proofing Content: As assistive technologies evolve, WCAG-compliant EPUBs remain usable.
  • Legal Compliance: Many countries (e.g., U.S. under ADA, EU under EN 301 549) require digital content to be accessible.
  • Broader Audience Reach: Accessible eBooks cater to readers with disabilities, expanding your market.
  • Enhanced User Experience: Well-structured EPUB3 files improve navigation for all users.
