THE KITCHEN TRIANGLE

The kitchen triangle or kitchen work triangle is a simple rule of thumb useful in kitchen design, first developed by ergonomists in the mid 20th century, who wanted a way of measuring and maximising efficiency of movement (and thus minimising space and thus cost) between the three main centres or ‘stations’ of activity in the kitchen: food storage (the fridge and pantry), food preparation (the sink) and food cooking (the stove/oven). Generally the sink, the most used part of the kitchen, should be in the centre of the arrangement, i.e. between the other two stations. The idea is that if you draw a triangle with one of these three stations at each of its three corners, then the total length of the sides of the triangle should be between four to six metres (some sources cite five to seven metres or other figures). At any rate, anything less than the lower figure probably means your kitchen will be too cramped; and anything higher might suggest that your kitchen is probably going to be too large and you will be spending too much time and effort walking between the three stations.

The kitchen triangle is also useful in making sure that no pedestrian traffic crosses any part of the working space of the kitchen- people going through the kitchen to bedrooms, laundry, etc. should not have to cross paths with or dance around a person using the kitchen. Also, the lines of movement and sight between stations should ideally not be ‘broken up’ with tall cabinets, wall ovens, and the like- there should be open countertop between each station.

As a general rule of thumb, the kitchen triangle is still a valid way of evaluating the basic functionality of your kitchen, even seventy odd years after the concept was first introduced. Of course, each design situation and brief is unique, the kitchen triangle is not appropriate for all kitchens, and these days things like kitchen islands can complicate matters- next week we will look at some of these factors in more detail.
