Keep the quiet zone
Leave clear space around every side of the code. Do not let text, borders, or artwork crowd it.
QR code size calculator
Start with a QR size people can scan comfortably.
Enter the farthest likely scanning distance. The estimate uses a conservative 10:1 distance-to-code ratio and a 20 mm minimum, then converts it to print pixels.
This is a practical starting estimate—not a guarantee. Always test the final artwork on the intended material and devices.
Three details that matter as much as size
Protect contrast
Use a dark code on a light background. QR Inspector rejects color combinations that are too weak for dependable scanning.
Test the final piece
Gloss, curvature, lighting, camera angle, and print quality all affect scanning. Test at and beyond the expected distance.
Need a scalable print file?
QR Inspector downloads SVG for vector workflows and high-resolution PNG for common design tools. Both include a standard four-module quiet zone.
