LINKMINT / PRINT HELPER
QR Code Print Size Calculator
Calculate the physical width of a QR symbol from its module count and quiet zone.
Calculated overall width
This is a geometric calculation, not a scan guarantee. Content density, contrast, surface, viewing distance, camera and print quality still affect scanning.
What is a QR module?
A module is one small square in the QR pattern. The printed symbol consists of the data matrix plus a blank quiet zone around it. DENSO WAVE specifies a quiet zone four modules wide on every side.
Example calculation
A 29-module matrix with four quiet-zone modules on each side is 37 modules across. At 0.5 mm per module, the overall printed width is 18.5 mm.
How to use the result
Create the QR code, count or identify its matrix modules, choose the intended module width, and export enough pixels for the printer resolution. Preserve the aspect ratio and blank border, then test a finished sample. See the QR printing guide and DENSO WAVE code-area guidance.
