Use the Kitchen Triangle for Space Planning

When designing your kitchen remodel or new build, it can be difficult to juggle all of the design concepts and make them work together. That is why it helps to have a shortcut or a rule of thumb to use as a controlling theme.

The kitchen triangle is one such shortcut that has been used for decades and still holds true for many kitchen design projects. Applying the kitchen triangle design concept means that you have automatically solved a host of kitchen design problems relating to ergonomics, workflow, and aesthetics.

What Is the Kitchen Triangle?

The kitchen triangle is a design concept that regulates activity in the kitchen by placing key services in prescribed areas. The idea is that the cook should be able to move unimpeded between three points—sink, stove/oven, and fridge—and that the distances between those points should not be too far or too close.

When the workflow is unimpeded, this means that two points on the triangle form a straight or relatively straight line, and this line is not blocked by the third point in the triangle or by any other obstruction.

Distances matter with the kitchen triangle, too. While it may be apparent that long distances are a problem, it might not be so apparent that locating kitchen services too close is also a problem. When points on the triangle are too close, drawers may clash with doors, refrigerators may open directly onto stoves, and sinks may be too close to stoves to permit space for preparing the food.

When you add up the three legs of the triangle, they should not total more than 26 feet. No leg of the triangle should be more than 9 feet long and no leg should be less than 4 feet long. Keep in mind that these are only recommendations. If you need to work outside of those space limitations, you can do so; you just need to be aware that workflow will be affected by the change.

Kitchen Triangle's Three Points

Kitchen Sink

The primary sink is usually located on the perimeter of the kitchen, though sometimes it may be located on a kitchen island. Supplementary sinks are not figured into the kitchen triangle. You will also need to plan for space on either side of the kitchen sink for placing dishes or preparing food.

Stove and Oven

With the kitchen triangle, the assumption is that this is a combined stove/oven. If the stove and oven are separate, the two are located within 2 to 3 feet of each other. You can change it slightly by having a wall oven located out of the triangle since baking tends not to be a frequent kitchen activity. If you do happen to be an avid baker, then make certain that the wall oven is part of the triangle.


The refrigerator, while definitely part of the kitchen triangle, ranks as the least important point of the triangle. The assumption is that the cook will not be constantly ferrying items back and forth from it. If one point must be a little bit farther away, it will be the fridge.


Make sure that the door of the refrigerator opens into the triangle, not outside of it. This allows for easier access to the food and prevents the fridge door from itself becoming an obstruction.

Kitchen Island Space Considerations

Kitchen islands are especially valuable when planning your kitchen around the triangle concept. Without an island, the chief way to build a triangle is by forming the three points within an L-shaped kitchen or across the aisle in a galley kitchen or a U-shaped kitchen.

But adding a kitchen island is a shortcut to easier kitchen triangle design. On the island, you can locate a cooktop or a primary sink. Across the aisle would be the refrigerator or the primary sink, cooktop, or stove/oven combination. Distances between the island and the main countertop area will nearly always be the correct distance.

The downside to using the kitchen island as one of the points of the triangle is that electricity, water supply, and water drainage lines will need to be run under the floor and up into the island. While this need not be a deal-breaker for designing your kitchen, you should budget the additional costs. When these services are all clustered in the main countertop area, it is easier and much less expensive.
