Size for distance
A common starting point is a QR width around one tenth of the furthest scan distance. Increase it for dense data, movement or difficult lighting.
Print production
Print QR codes people can scan.
A good QR proof is plain, high contrast and tested at the real size. These are the decisions to make before you send artwork to print.
Protect the pattern
Keep four clear modules around every side. Do not place a border, text, logo or photograph inside that quiet zone.
Test the real proof
Print at final size on the actual material. Test at the shortest and longest expected distances with at least two phones.
Dark on light wins
Black on white is the safest combination. Brand colours can work when the foreground is substantially darker than the background.
Use vector for print
SVG, PDF or EPS stays sharp at any size. If you use PNG, export it at the final dimensions rather than enlarging a small file.
Watch gloss and curves
Reflection and distortion affect cameras. Matte finishes and flat surfaces are easier to scan than glossy wraps or tight curves.
Give people room
Keep the code reachable, well lit and away from folds, floor level, moving parts and places where a hand naturally covers it.
Before the full print run
- Scan from the expected distance
- Test in bright and dim light
- Open the final destination on mobile
- Keep a dated copy of the approved artwork
After installation
- Scan every distinct placement once
- Check curved or laminated versions again
- Monitor the destination for broken links
- Keep replacement artwork accessible
