There are many models to choose from when shopping for a small refrigerator. Also known as a compact refrigerator or a mini refrigerator, these pint sized appliances are range from single can holders to anything smaller than 18 cubic feet. At which point it is considered a standard sized refrigerator. The most common models that come to mind are between 2.8 to 4.4 cubic feet.
The designs that are around 2.8 cubic feet are sometimes referred to as compact cube refrigerators because of their roughly cube shaped contour. These are best for beverages since they cannot hold much else beyond a snack and some drinks. It is great for game rooms or offices where a full sized fridge will serve the primary purposes of a refrigerator. One of the best things about such small units is the small price tag which usually runs around 0.
Then there are mid-sized refrigerators that can be anything between 2.5 and 10 cubic feet of storage space. These usually have a small full-width freezer compartment which is much more useful than the half-width freezer compartments of most compact cube refrigerators. This mid-sized small refrigerator is more often used in small apartments or dorms where there is a need to store a couple days worth of groceries for one person.
With more room for storage, an apartment sized refrigerator is often used as it is named, in small apartments where the limited kitchen space prevents the person from having a full sized refrigerator. This class of mini refrigerators range anywhere from 5 cubic feet to the upper limit of small refrigerators at 18 cubic feet.
On the larger end of the scale, the models tend to be large enough to have a separate freezer compartment. Then there are ice maker and keeper available as an additional feature for refrigerators of this size. Larger refrigerators have more space and flexibility to include additional conveniences and features.
