Round and circular QR codes: how to make one that still scans
A round QR code is a normal QR code with rounded data modules and circular finder patterns. Done carefully, it scans as reliably as the square original — the trick is knowing which parts of the code carry the data and which parts are just style.

What you can safely change
The three large squares in the corners are finder patterns — they tell the scanner where the code is and how it is oriented. You can restyle them (rounded or circular) as long as the overall shape and contrast stay clear.
The small data modules can be turned into dots or rounded squares. Increasing the error-correction level gives the scanner more room to tolerate the change.
- Round the data modules into dots
- Restyle the three corner eyes as circles
- Raise error correction before adding a logo
- Keep strong contrast between modules and background
What breaks a scan
Two things ruin a custom code: low contrast and a logo that covers too much of the data. Aim for a dark foreground on a light background, and keep any center image small.
- Light modules on a light background
- A logo covering more than about a fifth of the code
- Removing or hiding a corner eye entirely
- Scaling the code below the minimum print size
Design a round code in seconds
In the builder, choose the dots or classy module shape and a circular eye style, pick your brand colors, then test the result with two different phones before you print.
