I am doing pulls on wall cabinet doors and am wondering what length to go with. Mocked up in my pic has a longer one on the large one cabinet door with a 5 1/16 length and the smaller double doors has 4 7/16" length. Is it off that the smaller doors have a shorter pull or does it look more proportionate this way? When I put the smaller handle on the larger doors it is too small but the longer handle on the smaller door looks too long.

Can they be different sizes or should they all be one size?
