QR code size calculator
A dense code needs more room. Enter the planned content and scanning distance for a practical starting estimate.
Estimate a print size
This estimate uses the actual QR density of your content and a distance rule of thumb. Test a real print before ordering a large run.
How the estimate works
- Distance rule
- A common rule is to scan from about ten times the code width. QRnook adjusts it for how dense your content makes the code.
- Conditions matter
- Choose the environment that matches reality. Low light, glare, curved surfaces or a moving viewer call for a larger code.
- Always test
- The result is a starting point. Print one sample at the planned size and scan it from the planned distance before ordering a full run.
