Most householdsuse the freezer-on-top-and-refrigerator-on-bottom style, which has been the basic style since the 1940s.

• Traditional style (aka top-mount fridge) — 1940s to present. Freezer top/refrigerator bottom (although most of the earlier models, some of the cheaper later models, and still some mini-fridges use the freezer chest, or what is known as the freezer-in-the-fridge). A separate freezer compartment — not located within the larger refrigerator compartment — became the industry standard during the early- to mid-1960s.

• Side-by-side style (aka American-style fridge) — introduced by Amana in 1949 but not popular until 1965–present; left side is freezer and the right is refrigerator.

• Top-refrigerator/bottom-freezer style (aka bottom-mount fridge) — mid-1950s to present.

• French-door style — late 1990s to present. Two French doors for refrigerator and bottom freezer.

• Four-door French-door style — mid-2000s to present. Two French doors for refrigerator and bottom freezer plus an extra door above the freezer which can function as a refrigerator or freezer.

• Door and drawer, similar in concept to drawer style ovens, whereby the entire contents of the freezer are pulled out on gliders.

• Four door style — 2013 to present. Four-door style fridge with a French-door refrigerator section and a lower section divided into a freezer on the left and an area that can be converted between fridge and freezer space on the lower-right.

In the early 1950s most refrigerators were white, but from the mid-1950s through present day designers and manufacturers put color onto refrigerators. In the late-1950s/early-1960s, pastel colors like turquoise and pink became popular, brushed chrome-plating (similar to stainless finish) was available on some models from different brands. In the late 1960s and throughout the 1970s, earth toned colors were popular, including Harvest Gold, Avocado Green and almond. In the 1980s, black became fashionable. In the late 1990s stainless steel came into vogue, and in 2009, one manufacturer introduced multi-color designs.[9]

Most home refrigerators weigh between 200 pounds (91 kg) and 450 pounds (200 kg), with some models weighing up to 875 pounds (397 kg).
