QR Code Printing Guidelines & Best Practices

1 answer

For QR Codes that will be scanned up close (e.g., on Products, in Magazines):

  • 32 mm (1¼ inches), excluding the margin, is the minimum size that guarantees that all camera phones on the market will be able to properly read the QR Code.
  • 26 mm (1 inch), excluding the margin, is the recommended size that works with roughly 90% of the phones on the market.
  • 10 mm (.4 inch), excluding the margin, works well with the latest smartphones, which have improved macro capabilities.

For QR Codes that will be scanned from afar (e.g, on Signage):

  • The simplest approach is use a QR Code size that is at least one tenth of the scanning distance, excluding the margin.
  • For example, a code on a Billboard that will be scanned from a distance of 10 m (32 ft) should be at least 1 m (3.2 ft) in size, excluding the margin.

For all QR Codes:

  • Use a minimum margin of 4 blocks.
  • Good contrast between the background and the QR Code color is very important. The QR Code should have a dark color with a light background color.
  • Some QR Code Readers can not read reversed colors (e.g., light color with a dark background color, white with black background color).
