-To match the QR-Code pixels with a valid lego base plate size I tried a few options to find a match.

 I will go with the 25% padding option as this will lead to better scanning results without any downsides.

 ## Bricklink Studio
 
-I didn't find a cool way to automatically build the QR-Code in Bricklink Studio so I just opened the image of the QR-Codes shared above and rebuilt it using different flat tiles. Classic QR-Codes have black and white pixels so I went with that look and chose a white 50x50 baseplate and used different sized black tiles for the pixels.
