HOW THIS TOOL WORKS
Print-size calculator
QR modules = 17 + 4 × version. Include four quiet modules on every side; mm/module = 25.4 × dots/module ÷ dpi.
Worked example
Version 3, 400 dpi, 4 dots/module → 9.398 mm
Know the limits
The formula predicts geometry, not scan success. Our 0.4 mm guideline is deliberately more conservative.
