QR Code Information
Error Correction Levels
- Low (L): ~7% damage recovery
- Medium (M): ~15% damage recovery
- Quartile (Q): ~25% damage recovery
- High (H): ~30% damage recovery
Error correction allows QR codes to be read even if part of the code is dirty or damaged. Higher levels increase redundancy, making the code more robust but also larger and more complex.
Color Guidelines
- • Use high contrast between foreground and background
- • Minimum contrast ratio of 3:1 recommended
- • Dark foreground on light background works best
- • Avoid similar colors or low contrast combinations
- • Test readability before printing or publishing
While QR codes can be customized with colors, maintaining good contrast is essential for reliable scanning across different devices and lighting conditions.
Best Practices
- • Test QR codes before printing
