We often receive questions about the ideal sizes for QR Codes. Since we use them on our own printed materials, we also spent a decent amount of time testing what works. We recently ran a test of a Website QR Code at 6 different sizes. We used 4 different readers to see what kind of results we could come up with. The results are below:
