QR Code Design Considerations

| Element | Best Practice | Impact on Scannability | |---------|---------------|------------------------| | Error Correction | High (30%) recommended for artistic QR | Allows more design freedom | | Logo Size | Max 30% of QR area | Larger logos reduce reliability | | Color Contrast | Dark modules on light background | Essential for scanning | | Quiet Zone | Maintain white border | Required for reliable scanning | | Module Style | Rounded, dots, or custom shapes | Minimal impact if consistent |

Best Practices

Design Guidelines

  • Contrast is Key: Maintain strong contrast between modules and background
  • Test Scannability: Always verify the generated QR code scans properly
  • Error Correction Level: Higher levels allow more artistic freedom
  • Quiet Zone: Preserve white space around the QR code
  • Module Clarity: Keep modules distinct even with artistic styling

Color Guidelines

  • Dark on Light: Traditional contrast works best
  • Avoid Red/Green: May cause issues for colorblind users
  • Consistent Styling: Apply effects uniformly across all modules
  • Background Contrast: Ensure sufficient contrast with placement surface

Size Recommendations

| Use Case | Minimum Size | Recommended Size | |----------|--------------|------------------| | Business Card | 2cm x 2cm | 2.5cm x 2.5cm | | Table Tent | 3cm x 3cm | 4cm x 4cm | | Poster | 5cm x 5cm | 8cm x 8cm | | Billboard | 15cm x 15cm | 20cm x 20cm |

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

| Mode | Best For | Speed | Quality | |------|----------|-------|---------| | max | Final production QR codes, print materials, branded assets | Slower | Highest | | eco | Quick previews, concept testing, multiple variations | Faster | Good |
