How much clearance does a 36 inch fridge need to fit?

A 36 inch fridge typically needs around one to two inches of clearance behind for ventilation and about a quarter to half an inch above the top. Side clearance varies by model; some require nearly zero if they use zero-clearance hinges. Door swing also requires space, so allowing a couple of inches in front or offsetting the fridge forward helps it open fully next to walls or tall cabinets.
