QR scan difficulty · measured

How hard is your QR code to scan?

Every code we measured at seven sizes, on one scale from easy to hard, shaded by how many of eight scanners read each one. Add pictures of your own codes to see where they fall.

Read by five of the eight scanners. Nothing is kept.

Shades count the scanners that read each code at 1280 pixels. The curve’s shape is an illustrative mix of the sets, not a count of them.
