Print and test
- Print at least 2 cm (0.8 in) wide for codes scanned at arm's length. A common rule of thumb: width ≈ scanning distance ÷ 10. A poster read from 2 m needs about 20 cm.
- Keep the blank quiet zone (4 modules) around the code. Do not let borders, text or photos touch it.
- Use dark modules on a light background with strong contrast. Avoid glossy laminates that cause glare under shop lights.
- Use the SVG or PDF download for print shops; they stay sharp at any size.
- Test the printed proof, not the screen: try at least one iPhone and one Android phone, at the real distance and in the real lighting, before printing the full run.
- Send the generated link to a friend first (shown under Show encoded content) to check it opens the right chat.
