A kitchen is a room used for cooking and food preparation. The main functions of a kitchen are cooking, preparing food, dining, food storage, entertaining, dishwashing, and laundry. A key consideration in kitchen design is the work triangle, which is an imaginary line connecting the three primary work stations: food storage, preparation/cooking, and clean-up. The work triangle should have a perimeter of less than 26 feet to avoid traffic flow problems. Knowing kitchen layout and the work triangle is important for efficient use of space and movement within the kitchen.
