Good afternoon!

Recently, I have been dealing with the issue of generating a large number of unique QRs that are placed on the company's products. There was a question of damage to the printed codes (stripes, scuffs). As I understand it, solutions can be sought in two directions at once:
1. Increase the level of correction to the 4th
2. Reduce the graininess of the code (the length of the encoded message)
But I could not find articles that would describe the QR generation technology in terms of "readability" and stability to damage. Including I could not even find a graph of the dependence of the size of the pixels in the QR on the length of the message (as I understood from their experiment, this dependence is not linear, but stepped). Can you help on this topic?
