QR codes on posters
Poster codes fail for one reason above all others: they are printed too small for the distance. Divide the expected scanning distance by ten to get your minimum code width, so a poster read from 3 meters needs a code around 30cm. Export the code as SVG and the edges stay sharp at any print size. The destination stays editable long after the paste-up.

The 10:1 rule
Scanning distance divided by ten gives the minimum code width. Three meters of distance means a 30cm code. When in doubt, print larger.
SVG for sharp edges
A PNG scaled up to poster size blurs the module edges. Download the SVG and the printer renders clean squares at any size, A4 or billboard.
New campaign, same poster
Re-point the dynamic code when the promotion changes, and posters already on walls sell the new thing.
Common questions
How big should a QR code be on a poster?+
Use the 10:1 rule: minimum code width is the scanning distance divided by ten. A hallway poster read from 2 meters wants at least 20cm.
Matte or glossy paper?+
Matte scans better under direct light. Gloss reflects lamps and sunlight straight into the camera, which can blind the scan at certain angles.
Can I reuse the poster after the event?+
If the code is dynamic, yes. Point it at the next event or your main site, and the printed poster keeps earning its wall space.
