QR Code Best Practices

  • Test before printing - always scan your QR code before mass printing
  • Add sufficient quiet zone - keep white space around the code (4 modules minimum)
  • High contrast - dark code on light background for best readability
  • Minimum size - at least 2cm × 2cm for reliable scanning
  • Dynamic QR codes - use for campaigns where you need to change the destination URL
