QR Menu Accessibility: Building Inclusive Digital Menus

Visual Accessibility

Color Contrast

Text must have sufficient contrast against its background for users with low vision or color blindness.

• WCAG AA: 4.5:1 ratio for normal text, 3:1 for large text (18px+ or 14px bold)
• WCAG AAA: 7:1 ratio for normal text, 4.5:1 for large text (ideal target)
• Don't rely on color alone to convey information (add icons or text)
• Test with contrast checker tools like WebAIM Contrast Checker

Text Size & Readability

• Base font size: 16px minimum (many use 18px for better readability)
• Allow users to resize text up to 200% without breaking layout
• Use relative units (rem, em) not fixed pixels
• Line height: 1.5x font size for body text
• Limit line length to 60-80 characters for readability

Image Accessibility

• Add alt text to all food images: "Grilled salmon with lemon and asparagus"
• For decorative images, use empty alt (alt="") so screen readers skip them
• Don't put important text in images—use HTML text instead
• Ensure images are not the only way to identify menu items

Screen Reader Compatibility

Screen readers convert text to speech for visually impaired users. Your menu needs proper structure to be navigable:

• Use semantic HTML: proper heading hierarchy (H1 → H2 → H3)
• Menu categories as H2, items as H3 or list items
• Use descriptive link text ("View full menu" not "Click here")
• Add ARIA labels where needed (aria-label="Add to order")
• Ensure all interactive elements are announced correctly
• Price information should be read naturally ("Fifteen dollars" not "1500")

<h2>Appetizers</h2>
<article>
  <h3>Bruschetta</h3>
  <p>Grilled bread with tomatoes, basil, garlic</p>
  <p aria-label="Price: 12 dollars">$12</p>
</article>

Motor Accessibility

Users with motor impairments may navigate using keyboards, switches, or voice control:

Keyboard Navigation

• All interactive elements accessible via Tab key
• Visible focus indicators (outline or highlight when focused)
• Logical tab order that follows visual layout
• Skip links to jump to main content or categories
• Escape key closes modals and popups

Touch Targets

• Minimum touch target size: 44x44 pixels (WCAG recommendation)
• Adequate spacing between touch targets to prevent accidental taps
• Buttons should be easily tappable even with tremors
• Avoid hover-only interactions (no hover on touchscreens)

Cognitive Accessibility

Help users with cognitive disabilities, learning differences, or those unfamiliar with technology:

• Clear, simple language—avoid jargon and abbreviations
• Consistent navigation and layout across pages
• Provide clear feedback for actions (order confirmed, added to cart)
• Don't use auto-advancing carousels or auto-playing media
• Allow undo actions where possible
• Break complex tasks into simple steps
• Use icons with text labels, not icons alone
• Provide sufficient time for interactions (don't auto-timeout)

Testing Your Menu

Automated Tools

• WAVE Web Accessibility Evaluator (free browser extension)
• axe DevTools (Chrome extension)
• Lighthouse (built into Chrome DevTools)
• Pa11y (command-line tool for CI/CD)

Manual Testing

• Navigate entire menu using only keyboard (Tab, Enter, Arrow keys)
• Test with a screen reader (VoiceOver on Mac/iOS, TalkBack on Android)
• Use browser zoom to 200% and check nothing breaks
• View in grayscale to check color contrast
• Test on various devices and screen sizes

Don't Forget Physical Accessibility

QR code accessibility isn't just about the digital experience:

• Always have physical menus available for those who can't scan QR
• Print large-text menus on request
• Place QR codes at wheelchair-accessible heights
• Ensure QR placement is well-lit for scanning
• Consider braille menus for visually impaired guests
• Train staff to assist customers who need help
