QR Code Best Practices
A QR code only helps if it scans first time. These practices maximise reliability.
Quiet zone and contrast
Leave clear space around the code and keep dark-on-light contrast high. Busy backgrounds and tight margins are the main reasons codes fail to scan.
Size and testing
Size the code for the expected scanning distance — bigger for posters, fine for screens — and test on more than one device before publishing.
Frequently asked questions
Can I use this for production work?
Yes, for inspection, formatting and quick generation. Still review the output before committing it to production code or configuration.
