The basics in one minute
- Size: about one tenth of the scanning distance for a short link, never under 0.8 inch in print. Long links and logos need more.
- Contrast: dark code on a light, plain background.
- Quiet zone: a blank border of about 4 dots around the code.
- Dynamic beats static for print: shorter links, smaller codes, and you can change the destination after printing. See the dynamic QR code generator.
- Call to action: tell people what they get for scanning.
- Track by area: a different code per route or neighborhood shows where responses came from. See how to track EDDM by route.
