Standard refrigerators vary widely in size. Generally, standard refrigerators range from 14 to 28 cubic feet, with most falling in the 18 to 23 cubic foot range. Standard apartment sized refrigerators can be as small as 10 cubic feet.
The size of refrigerator needed for a home or business varies depending on how many residents or employees are using it. Smaller refrigerators are not always a lot more energy efficient than larger ones. Smaller kitchens can look overwhelmed if refrigerators are very large. Actual refrigerated space can vary when comparing side-by-side refrigerators and those with freezers on the top or bottom.
