QR Code Size Calculator
Estimate a conservative minimum QR width from the furthest expected scanning distance.
Starting rule: scanning distance ÷ 10
Why this is an estimate
Camera quality, lighting, print finish, QR complexity, contrast and damage all change scanning range. A larger code is usually safer; this calculator is not a guarantee.
Print checklist
- Keep a clear quiet zone around every side
- Use strong foreground/background contrast
- Avoid folds, glare and textured material
- Test the final-size proof before the full print run
