Physical Print Specifications

Physical Print Size & Distance Specifications

Formula: D = 10 × S

When printing QR codes on physical media, choosing the correct size guarantees rapid optical detection. Standard scanning optics follow the ratio D = 10 × S, where D is maximum scanning distance and S is the side length of the QR square.

Commercial Printing Best Practices

  • Maintain a minimum 4-module quiet zone around the QR matrix perimeter.
  • Ensure strong contrast between foreground modules and background surface.
  • Export in SVG vector format for crisp scaling across all print sizes.
  • Always test scan printed samples with iOS Camera and Android Google Lens before mass production.

Scanability Safety & Reed-Solomon Error Correction

Aesthetic Customization Guidelines

  • Keep logo coverage below 25% of total matrix surface area.
  • Use dark module colors on light background surfaces for fastest optical scanning.
  • Preserve clean quiet zone margins without overlapping graphic artwork.
  • Verify camera detection under both daylight and ambient indoor lighting.
