Refrigerators vary in styles, models and sizes.Top-mount refrigerators, which place the freezer over the refrigerator compartment, are considered traditional refrigerators and range from 23 to 36 inches in width, 24 to 33 inches in depth and 65 to 69 inches in height.
The interior volume of a top-mount style refrigerator ranges from 10 to 25 cubic feet. The side-by-side unit is also a common style of refrigerator. These styles keep frozen food on one side and fresh food on the other. Side-by-side units can range between 30 and 36 inches wide, 29 to 35 inches in depth, and 67 to 70 inches in height, with 22.5 to 31 cubic feet in volume.
