How small can a QR code be?
The smallest recommended size for a QR code depends on its complexity and scanning distance. Generally, a QR code should be at least 1 x 1 cm (0.4" x 0.4") for basic ones. However, for better readability, we reccomend a size of 2 x 2 cm (0.8" x 0.8") or larger is ideal, especially if it contains more data.
Test your code before print
We can not test QR codes before printing, so the best thing is to always make sure to scan and verify yours before placing an order.
