Combining different pulley sizes?

Hi,

I'm planning the CoreXY system for my new printer.

I have two 20 teeth GT2 pulleys that I want to use for the motors. Then 2 idlers without teeth, as well as 6 other idler pulleys with teeth. These idler pulleys are larger and of the same size of the teethless idlers, which I think is better because the belt doesn't get bend so tight. These idler pulleys have 25 teeth.

My question to you is: Can I mix the different pulley sizes, so 20 teeth on the motors and 25 teeth idler pulleys? As far as I know it's no problem but I would like to go sure. Thank you.

Yes, but make sure you keep the belts parallel to the axes
