When purchasing a new refrigerator, consumers should consider how many people may use the appliance. Each adult in the home should have 4 to 6 cubic feet in the refrigerator. Refrigerators with the freezers on top generally have a smaller capacity than the other models and range from 10 to 25 cubic feet.
