Larger viewing distance needs a larger code. As a starting point, use about 1 cm of QR width for every 10 cm of expected scan distance, then test in real lighting.
Suggested sizes
| Use | Minimum QR size | Notes |
|---|---|---|
| Business card | ~2 × 2 cm | Keep quiet zone; avoid tiny logos |
| Flyer / A5 | ~2.5–3 cm | Works at arm’s length |
| A4 poster near desk | ~4 cm | Increase if lighting is poor |
| Wall poster / window | 6 cm+ | Match hallway viewing distance |
Export tips
- Generate at 512×512 or 1024×1024 PNG for clean print scaling.
- Do not stretch non-square; keep modules sharp.
- Print a proof on the final paper stock — glossy glare can hurt scans.
