Print check
Before you print 500 menus, check the QR code will scan. Upload your design and tell us how big it prints and how far away people will be. Your file stays on your device.

The rules we check
- Size vs distance: a code should be at least one-tenth as wide as the scanning distance (30 cm away → 3 cm wide), and never under 2 cm.
- Quiet zone: a clear light border around the code, about 4 of its little squares wide.
- Contrast: dark code on a light background. Light-on-dark codes don't scan on some phones.
