QR Code Print Size Guide
A QR code print size should match the way people will scan it. Codes meant for a table card can be smaller than codes meant for a poster or storefront window. The farther the viewing distance, the larger the printed code should be.
Do not shrink the code until the scan becomes fragile. Leave enough quiet space around it, keep the surface flat when possible, and test a real print before large distribution. A good print size is one that works in the real environment, not just on a design mockup.
If you need the code itself, create it with QR Code Generator - QR Creator. For related reading, compare QR Code Design Best Practices, the FAQ center, and Support.
