A kitchen is a room or part of a room used for cooking and food preparation. In the West, a modern residential kitchen is typically equipped with a stove, a sink with hot and cold running water, a refrigerator and kitchen cabinets arranged according to a modular design. Many households have a microwave oven, a dishwasher and other electric appliances. The main function of a kitchen is cooking or preparing food but it may also be used for dining, food storage，entertaining, dishwashing, laundry.

Kitchen cabinets are the built-in furniture installed in many kitchen and import parts in the kitchen. Kitchen cabinets are for storage of food, cooking equipment, and often silverware and dishes for table service. Appliances such as refrigerators, dishwashers, and ovens are often integrated into kitchen cabinetry. There are many options for cabinets available at present.

Cabinet dimensions are specified with width first, height second, depth last. The width–height–depth is a generally accepted convention.

  ·Base cabinets are usually 24 inches (610 mm) deep and 34 1⁄2 inches (880 mm) high to accommodate a countertop surface normally 36 inches (910 mm) above the floor.

  · Wall cabinets are usually 12 inches (300 mm) deep. Their heights are often 30 inches (760 mm), for example, if mounted to a soffit. In a kitchen with 8-foot-high (2.4 m) ceilings, a 36-inch-high (910 mm) wall cabinet will leave about 6 inches (150 mm) of space above the cabinet which can be covered with a crown molding; a full 42-inch-high (1,100 mm) wall cabinet will run straight to the top of the ceiling. Wall cabinets are sometimes called "upper cabinets." The distance from countertop to wall cabinet is usually 18 inches (460 mm), but this distance is sometimes less if there is undercabinet lighting. Cabinets can have an open top for displaying ornaments. Ceilings higher than 9 feet (2.7 m) can permit another level of cabinets.
