QR Code's quietzone

Quietzone

The quietzone is an important area surrounding the QR code. It makes the QR Code more readable, and is sometimes crucial. Its size is automatically calculated by the generator.

QR Code size

Size

We offer a full range of sizes. The size we recommend depends on the expected reading distance eg:

  • 3cm x 3cm for reading from 10cm (an A4 document...)
  • 33cm x 33cm for reading from 3m (an A3 poster...)

QR Code redundancy

Redundancy

The redundancy in a QR code is also its strength. There are 4 levels of redundancy : L,M,H and Q . The higher the level, the more resistant the QR code is to damage (fading, logo overlay etc.). A lower level of redundancy makes the QR code smaller and more readable.
