The right QR size depends on scan distance. The further away people scan from, the bigger your QR needs to be.
01
A simple rule of thumb
If you’re unsure, print larger. Small QRs are the #1 reason for failed scans on posters.
- Business card: compact but high contrast
- Poster: large enough from a few feet
- Signage: test from the real viewing distance
02
Don’t forget the quiet zone
Leave margin around the code so scanners can detect it. Tight cropping is a common mistake.
03
Test before you print in bulk
Print a single sample, try scanning on multiple phones, and test under real lighting.
Quick takeaway
Scan distance drives QR size. Print a sample, test, then scale up.
