QR Codes should be printed in the appropriate size according to your print medium and ideal scanning distance. We recommend a minimum size of 2 x 2 cm (0.8 x 0.8 in) for Dynamic Codes and 3 x 3 cm (1.2 x 1.2 in) for Static Codes. For more tips on how to print your QR Codes, check out our printing guide and take a look at our blog article about QR Code size and scan distance.
