QR codes are encountered in different circumstances, fitting into one of the following distances.
Effectively zero distance. These QR codes are expected to be interacted with from a small distance; it can be as small as the camera focus on your device can go.
Examples of QR codes at intimate distances:
This is the distance individuals maintain between each other. The length of the arm plays a major role in defining this distance and it ranges between 1.5-2.5 feet (1/2 to 3/4 meters). QR codes that fit into the personal distance are QR codes that are in your arm distance after extending your arm towards them.
Examples of QR codes at personal distances:
This is the distance that people feel comfortable with, in a social situation. It measures between 6-12 feet (1.25-3.6 meters). QR codes that are expected to be interacted within a social distance are QR codes positioned in places where many people are gathered.
Examples of QR codes at social distances:
This is the distance considered to be well outside any social involvement. This distance goes between 12 feet and above (more than 3.6 meters). QR codes are expected to be interacted in a public zone. The most natural way to contact them is from a distance of 12 feet and above.
Examples of QR codes at public distances:
Every distance has an equivalent QR code size.
For QR codes that will be scanned up close e.g.; on Products, in Magazines.
For QR codes that will be scanned from afar e.g; on Signage.The ratio of the scanning distance to the size of the QR code should be close to 10:1
For all QR codes
* Please note, while Delivr provides high-level best practices, most label and packaging design require deeper bespoke analysis especially when deviating from a standard black and white code. That starts with a review of a PDF of the layout, requires an understanding of the type of printing method and materials, and may then move to a print trial. Always Test. Test. Test.
