Creating a QR code is relatively easy, but there are a couple of things to keep in mind to make the best image possible:
- Make the code easy to scan: the bigger the code, the easier it is for the scanner in your phone to "read" the image. The smallest size recommended is 1" x 1"
- Leave some white space around the code, at least 1/8" for the scanner application to visually cue in to the code.
- Keep links or linked information short--use Bit.ly or Goo.gl. The shorter the link or message you embed in the code, the better the resolution and link length, and the less crowded the code will look.
- Avoid QR code generators that re-direct the scanned link to their own product pages. The code generators below do not redirect links.
- QR codes enable content to be accessed via a mobile device, so make the end destination a mobile-friendly page.
Bit.ly & Goo.gl
- Both Bit.ly and Goo.gl can generate a QR code (and provide analytics) for any link you create. For Bit.ly, go here. For Goo.gl, gohere.
