Best Practices for QR Code Use

At MobiBrix, we underwent a series of tests that included testing QR Codes of different sizes on a variety of materials and in different weather conditions. Here's what we found:

Best Practices for Outdoor Signage

  • Anything smaller than a 4-inch square symbol (QR code) might not be readable by some smart phones. Our QR codes that you order will be 4-inches so that they can easily be read. 1-inch barcode equals about 1-foot scanning distance on most phones.
  • Using a larger QR code will depend on the amout of space left on the medium used. For example, on a 6-inch high sign the 4-inch QR code will be the largest size that can be used because the code requires a white border to surround it in order to be read.
  • Glares from the sun may cause difficulty for the code to be read.
4 feet of scan distance for 4" x 4" code

What We Recommend

A 1-inch barcode equals about 1-foot scanning distance on most phones, which means QR codes on real estate or other signage can not be read from the street. We recommend that you use at least a 4-inch square symbol (QR Code) to allow for best readability when scanned.
