DPP QR Code Print Size Calculator
Plan the print geometry of a QR Code from the address it will encode. The result includes the quiet zone and uses whole printer dots for each module. Test the final label on the actual product and scanners.
Your print plan
Calculate the symbol from your address and compare the achievable print size with the available space.
The suggested width combines DENSO WAVE’s four-dot guidance with Passvanta’s practical 0.3 mm module target. These are planning recommendations, not legal DPP size limits. Actual material, contrast, wear and scanner performance require physical testing.
