Side Clearance:
Another refridgerator-related issue is the side clearance.
In order to get the crispers out, modern refridgerators require at least a 90 degree opening of the doors. If you have the fridge positioned perpendicular to a wall or cabinetry, you will have to allow for the thickness of the refridgerator door, plus a possible plant-on door panel (should you have one), plus the fridge handle.
This can result in a required space of 2 3/8 inches and go up to 4 inches!
If the specs are unclear about this which they often are make sure to go to the appliance dealer to have a look at the fridge yourself.
Don't ever assume that a fridge will just fit in it's allocated spot!
A freestanding stainless steel Subzero fridge has been positioned next to a concrete stub wall. In order to open the door more than 90 degree we put a 2" stainless steel filler between fridge and wall.
