Print size guide
- Minimum printed size: 2 × 2 cm for close-up scanning (menus, business cards, packaging).
- Rule of thumb: scanning distance ÷ 10 = minimum code size. A poster read from 3 metres needs a 30 cm code.
- Leave a quiet zone (empty margin) of at least 4 modules, about 10% of the code width, on every side.
- Print at 300 dpi or use SVG/PDF; never upscale a small PNG.
- Avoid glossy laminates and curved surfaces that distort the code; test on the final material.
