What Size Should QR Codes Be on Restaurant Menus? Scan Distance Guide
The most common mistake restaurant owners make with QR codes is printing them too small. Your customers shouldn't have to squint or move their phones around to scan your digital menu. The right QR code size depends on where you place it and how far customers will scan from.
The Simple Formula
Use this rule: QR code size (in cm) = scanning distance (in cm) ÷ 10. For table tent cards scanned from 20-30 cm away, use a 3x3 cm QR code minimum. For wall posters scanned from 1 meter away, go for 10x10 cm or larger. Testing this at your restaurant in Mumbai or Bangalore will help you find what works best for your space.
Quick Size Reference
| Placement | Scanning Distance | Minimum QR Size |
|---|---|---|
| Table tent/menu card | 20-30 cm | 3x3 cm |
| Table sticker | 30-40 cm | 4x4 cm |
| Counter/entrance poster | 50-100 cm | 7x10 cm |
