For height and depth, we just matched the fridge, for width, it really depends on the space you have beside the fridge and the thickness of your brooms and such. For this one, the face of the drawer (thinking of it like a drawer on its side), is about a 4" wide face--you need clearance for the hook and the support wood strips as you see here. Works like a charm---good luck!
