- Alphanumeric: Up to 4,296 characters
- Binary/byte: Up to 2,953 bytes
- Kanji: Up to 1,817 characters

- L (Low - 7%): For clean environments, smallest QR code size
- M (Medium - 15%): Good balance, recommended for general use
- Q (Quartile - 25%): Better durability, for printing or outdoor use
- H (High - 30%): Maximum durability, for industrial use
Yes, QR codes with logos can be scanned reliably if designed properly:
- Keep logo size to about 10-15% of QR code area
- Ensure good contrast between logo and QR code
- Use high error correction (Q or H) when adding logos
- Test with multiple QR scanner apps
- Place logo in the center, avoiding position markers
While traditional QR codes are black and white, colored QR codes work well with proper contrast:
- Best combinations: Dark colors on light backgrounds
- Avoid: Red on black, similar colors with low contrast
- For printing: Use CMYK colors with sufficient contrast
- For digital: RGB colors work perfectly
- Test always: Verify scannability with actual devices
