There are basically three different types of apartment size refrigerators based on capacity: The smallest one is the compact cube refrigerator (1.5 to 2.7 cu ft). The next is the compact refrigerator with a capacity of 3.5 to 6 cu ft.
These refrigerators need very little clearance on the sides, typically 1/4- to 1/2-inch, for ventilation. Older models and models with doors that open on standard hinges need clearances that allow for the width of the door to open fully, typically 4 1/2 inches on the side or sides where doors are hinged.
