This is for my master bath so I cross posted in bathrooms. I would think the same ideas apply... so how do I place the handles?

The vanity style is shaker with flat slab drawer fronts. Cups pulls on the drawers with regular pulls (don't know what to call them) on the 2 doors. I saw a kitchen here that looked similiar with the cups centered on each drawer. Is that OK? The handles for the doors I am most worried about.

Is there a formula to use?
