Yes, there is a recommended size for printing QR codes. QR Codes should be printed at the correct size for your print medium to ensure optimal scanning. For dynamic codes, we suggest a minimum size of 2 x 2 centimeters (0.8 x 0.8 inches), while for static codes, we suggest a minimum size of 3 x 3 centimeters (1.2 x 1.2 inches). When QR codes are smaller than the recommended size, scanning issues can arise because some devices may not be able to scan QR codes of that size. This also applies to QR codes that are too large. In special cases, QR codes can be created at 1x1 cm, but attention must still be given to their intended use. To learn all about QR code sizes and create QR codes of the correct dimensions, you can visit the "QR Code Size Requirement for Printing" blog for detailed information.
