Print at that size or bigger
Download a PNG made for 300 dpi printing at exactly that size, or an SVG that stays sharp at any size.
Questions
Questions owners ask
How is the size worked out?
By a common rule of thumb: a simple code scans from about ten times its width, or eight times in dim light. Codes with more squares, from longer links, need to be bigger in the same proportion. We never suggest less than 2 cm.
Why does my link make the code bigger?
More characters means more squares in the code, and each square has to stay big enough for a phone camera to see. Short links make smaller, easier codes.
What is the white border for?
Scanners need a clear margin, four squares wide, around the code. Keep text, edges and patterns out of it.
Which error correction should I choose?
Standard suits most codes. Choose Sturdy for codes that may get scuffed outdoors, and Strongest if you put a logo in the middle. Stronger correction makes the code denser, so it needs to print a little bigger.
Should I test it?
Always. Print one copy at the size you plan, and scan it with two different phones from where your customers will stand.
