| Level | Recovery | Best For |
|---|---|---|
| L (Low) | ~7% | Clean digital displays, maximum data capacity |
| M (Medium) | ~15% | General purpose use, good balance |
| Q (Quartile) | ~25% | Printed materials that may get dirty |
| H (High) | ~30% | Industrial use, adding logos (with caution) |
Tips for Better QR Codes
- Size matters: For print, use at least 2cm × 2cm (0.8" × 0.8"). The scanning distance is roughly 10× the QR code size.
- Contrast is key: Dark foreground on light background works best. Avoid low-contrast color combinations.
- Test before printing: Always test your QR code with multiple devices before mass printing.
- Keep it simple: Shorter URLs create smaller, easier-to-scan QR codes. Consider using URL shorteners for long links.
- Higher resolution for print: Use 4x resolution (1000×1000px for 250px display size) for high-quality printing.
Common Use Cases
- Marketing: Business cards, flyers, posters, product packaging
- Restaurants: Digital menus accessible by scanning
- Events: Tickets, check-in, program information
- Retail: Product information, reviews, purchase links
- WiFi sharing: Guest network access in offices, cafes, hotels
