How should you choose a QR code print size?
A print checklist based on scan distance, quiet zone, contrast, and error correction.
There is no single safe QR print size; module count, scan distance, camera, and surface quality all matter. A practical starting point is a code width near one-tenth of the expected scanning distance, followed by testing the real print with target devices.
What changed in this update?
The print checklist now covers module density, quiet zone, and surface testing.
Why does a QR code need clear space around it?
The quiet zone lets a reader separate the QR boundary from its background. Keep at least four modules of clear space on every side; frames, text, and ads must not enter that area.
What should be tested before printing?
Print at 100% scale; test low-, mid-, and high-range phones; test matte and glossy surfaces separately; confirm the destination domain. Scan the final design PDF and a physical print sample.
What changes when a logo is added?
A logo covers data modules. Prefer Q or H error correction, strong contrast, and a small logo. Error correction does not guarantee recovery from poor design, so final print testing remains required.
Frequently asked questions
What is the minimum QR print size?
Because data density and scan distance vary, there is no universal minimum; 2–3 cm with a short URL is a common close-range starting point, not a substitute for testing.
Can a QR code use color?
Yes, if dark modules maintain strong contrast against a light background.
