Very good. However, I wanted to know the rules regarding how big that border has to be and how some QR codes have a logo in the middle. We all want pretty QR codes!

Also, given the choice between optimising for 21 x 21 modules or something a lot larger, what is recommended in this day and age? Is blocky best?

The logo corrupts the QR code. But QR codes can be generated with different levels of error correction.

So a code with a high error correction factor can repair a QR code with a logo obliterating the middle of the code.
