The most common measurements for mini refrigerators range between 1.7 and 4.5 cubic feet. They usually stand between 20 to 43 inches tall and measure anywhere between 17 and 19 inches wide. Most mini refrigerators have a depth between 18 and 20 inches.
While most mini refrigerators save on space and are able to keep things inside cold, some of the smaller refrigerators cost as much as a full-size refrigerator to run. To save the most space and money, it is recommended to shop for mini refrigerators with the Energy Star label. That way, a customer can get the performance she needs without paying for the energy use of a full-size refrigerator.
