Physical Print Size & Distance Specifications
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.
| Size Code | Physical Dimensions | Recommended Application | Max Scan Distance |
|---|---|---|---|
| XS | 2 × 2 cm | Business cards, small tags, stickers | 0.2m (20 cm) |
| S | 3 × 3 cm | Flyers, table tents, magazine ads | 0.3m (30 cm) |
| M | 4 × 4 cm | Brochures, product packaging, menus | 0.4m (40 cm) |
| L | 5 × 5 cm | Counter displays, window decals, signage | 0.5m (50 cm) |
| XL | 7 × 7 cm | Trade show banners, storefront signs | 0.7m (70 cm) |
| XXL | 10 × 10 cm | Large posters, booth displays | 1.0m (100 cm) |
| MAX | 15 × 15 cm | Billboards, vehicle graphics | 1.5m+ |
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.
