QR Code Size Guide: How Big Should Your QR Code Be?

QR Code Size Guide

The size of your QR code matters for scanability. Here's a comprehensive guide to choosing the right size for your application.

Minimum Size

For most applications, a QR code should be at least 2cm x 2cm (0.8 inches). For larger distances, increase the size accordingly.

Size vs Distance

A general rule is that the QR code should be at least 10% of the scanning distance. For example, if scanned from 1 meter away, the QR code should be at least 10cm.
