How big should a QR Code be?
A good rule: the code should be at least a tenth of the scanning distance. A code read from one metre away needs roughly 10 cm of print.
Resources
Get the print right the first time
Short, practical guidance from the mistakes we see most often.
Where to place codes indoors
Eye level beats table level, and stationary spots beat busy walkways. Table tents work because people are seated and unhurried.
Wording that lifts scans
Tell people what they get: 'Scan for today's menu' outperforms 'Scan me' because it promises an outcome.
Designing a code people trust
Keep strong contrast, leave a quiet margin around the code, and put your logo in the centre rather than over the corners.
What to measure after printing
Watch unique versus repeat scans, city concentration and time-of-day peaks. Those three tell you if placement, not design, is the bottleneck.
Static versus dynamic
Static codes bake the destination into the artwork. Dynamic codes point through a short link you can re-route later — the only safe choice for print runs.
