But AFAIK you can't do non-square QR codes. Plus, at small sizes, you lose a lot of space for the alignment marks.

- jillesvangurp 4y agoIf that matters to you, then yes that's a limitation. However, big qr codes are easier to scan. Making them smaller requires higher resolution scanning devices and more careful aiming of the device. So, it's not necessarily that big of a deal. The alignment marks are scaled along with the qr code. So, they don't use more space for smaller codes. The shape limitation is more of an esthetic thing. I don't think people care that much.
