Mind the surface
Curved boxes, foil and matte laminates all affect the scan. Keep the code on a flat, non-reflective panel where you can.
Where to use
Packaging that keeps talking after the sale
The box is the one thing every customer holds. A QR code turns it into setup help, registration, ingredient details or a reorder link — no insert to print or lose.
- Setup in a tap
- Editable link
- Fits small labels
Packaging QR size guide
Packaging codes are scanned up close, but small print and curves need extra margin. The rule of thumb: minimum size ≈ scan distance ÷ 10.
| Context | Minimum size | Scan distance |
|---|---|---|
| Small box / carton | 1.5 × 1.5 cm | up to ~15 cm |
| Standard product box | 2 × 2 cm | up to ~20 cm |
| Large carton / shipping box | 3 × 3 cm | up to ~30 cm |
| Curved surface (bottle, tube, can) | 2.5 × 2.5 cm (use higher error correction) | up to ~20 cm |
Note: Test on the actual material and finish — a code that scans on paper can fail on foil or a tight curve.

Packaging QR code FAQ
How small can a QR code be on packaging?
About 1.5 × 1.5 cm on a small carton and 2 × 2 cm on a standard box. Go a little larger on curved or reflective surfaces to keep it reliable.
Will it scan on a curved bottle or tube?
Yes, if it isn't wrapped too tightly. Keep the code on the flattest part, size it up slightly, and use a higher error-correction level.
Can I change the destination after the boxes are printed?
Yes, with a dynamic code — update the linked manual, video or offer without touching the printed artwork.
Does foil or matte lamination affect scanning?
It can. Reflective and very dark finishes reduce contrast, so test on the real material and keep a light, matte area behind the code.
What should packaging codes link to?
Whatever helps after the sale — setup guides (often a PDF), registration, product info or a reorder page.
What makes this placement work
- Test on the actual finish and curve. Foil, glare and tight cylinders can reduce reliability.
- Preserve the quiet zone around the code.
- Avoid decorative changes that reduce foreground/background contrast.
- Scan a production proof with more than one phone before approving the full run.
- Match the destination to the placement. Common choices include Product, PDF, Website.
