QR Codes on Product Packaging: Quick Size & Placement Guide

Size

Keep it at least 2 × 2 cm for close scanning. Longer links make denser codes, so keep URLs short or print the code larger.

Error Correction

• Medium :

  Fine for most flat, clean packaging.

• High :

  Better for pouches, curved bottles and anything that may get scratched.

Placement and Contrast

• Dark on Light :

  A dark code on a light background scans best.

• Flat Surfaces :

  Avoid seams, folds and tight curves.

• Clear Margin :

  Leave blank space around the code.

Conclusion

Right size, right error correction, good contrast - then test-scan a printed sample. Pair it with a product barcode from the Barcode Generator for a complete pack label.
