Kitchen work triangle

The kitchen work triangle is a concept used to determine efficient kitchen layouts. The primary tasks in a home kitchen are carried out between the cook top, the sink and the refrigerator. These three points and the imaginary lines between them, make up what kitchen experts call the work triangle. The idea is that when these three elements are in close (but not too close) proximity to one other, the kitchen will be easy and efficient to use, cutting down on wasted steps.

There are exceptions to this rule: in single wall kitchens, it’s geometrically impossible to achieve a true triangle—but efficiency can still be achieved through the configuration of the three items, and how far apart they are.

The kitchen work triangle is a model that was developed in the 1940s to address the efficiency of the kitchen space between the major work centers: Cooking (range), Preparation (sink/dishwasher) and Food Storage (refrigerator). It was designed to maximize the efficiency of a one-cook kitchen that stemmed from Taylorist principles that had to do with time-motion studies from around the turn of the century. The University of Illinois School of Architecture developed the work triangle to emphasize cost reduction by standardizing construction. This resulted in a variety of configurations.

The kitchen work triangle principle is used by kitchen designers and architects when designing residential kitchens:

Besides the work triangle itself, there are several rules of thumb to consider when planning a kitchen:

Quite a few things have changed since the 1940s, when the concept originated. After the Second World War, typically it was the housewife who cooked, cleaned, ironed, and served the family meals; kitchen sizes were generally smaller than today. The kitchen was considered a working area, and planning considered mostly utilitarian angles.

The original functions described with the kitchen triangle still exist within the modern-day kitchen. However, technologies (like microwaves and other appliances) and the way kitchens fit into the modern (Western) lifestyle have changed. Many kitchens have grown to accommodate more than one cook, so cooking zones were developed that are similar to the layout and zoning of commercial kitchens. With the housing boom and the expanding wealth of the Baby Boomers, the size of kitchens in the United States has expanded.
