What is the minimum recommended size for printing a QR Code?

One can’t determine an accurate minimum printing size for a static QR Code because static QR Codes can contain a variable amount of data.

On the other hand, a dynamic QR Code should be printed at least at 2 centimeters (0.8 inches) square to maintain reasonable scannability and sanctity.

Calculate the required size based on the print resolution

Follow this formula to calculate a QR Code's size in inches if you need to print a QR Code with, say 1024 pixels:

Size (in inches) = Number of Pixels / Print Resolution (in pixels per inch)

For example, if your QR Code has 1024 pixels and you are printing at a resolution of 300 pixels per inch, the required printing size would be:

Size = 1024 / 300 = 3.413 inches

Other important factors

Arriving at a QR Code's required size also depends on factors such as:

  • the data it contains,

  • QR Code reader tool,

  • lighting,

  • distance from the scanning device,

  • print quality, and

  • scanning device.

It's also crucial to ensure proper contrast, correct printing techniques, and suitable background colors so it can be scanned from a distance, even by devices with low-resolution cameras.

It's recommended to test the printed QR Code at various sizes and distances to verify its scannability to ensure the best results.
