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.
An average modern, full-sized refrigerator is about 18 cubic feet, but the larger the fridge, often the heavier it is. Specific models, such as side-by-side and french door types, can also be indicative of a heavier weight, since they average larger than the generic top freezer unit.
