What is the minimum size of a QR code?

The minimum size of a QR code for it to be read correctly is 0,4 inches or 1cm.

Here is a formula to help you choose the best size: Scanning distance / 10 = Minimum QR code size. (As long as this number is not lower than 0,4 inches or 1cm).

For example, if your customers will be 40" or 100cm away, your QR code’s size should be 4" or 10cm.

Always remember to test your QR code before printing it.

Good to know: When creating your QR codes via SQR you can set the "Error correction capability". This will make the QR more readable when you customize it.
