Planning efficient kitchen work areas
An efficient kitchen links sink, stove and refrigerator in a compact work triangle, groups tools at work centres, and sets work heights from body measurements.
The work triangle
The work triangle joins the three most-used points in a kitchen: the sink, the stove and the refrigerator (or main food storage). Most kitchen walking happens along its three sides, so a well-planned triangle cuts steps, time and energy. Home-management texts commonly suggest a total of about 12 to 22 feet (roughly 3.6 to 6.7 m): smaller is cramped, larger means wasted walking. The sink, used most often, is best placed between the stove and the storage, and no through traffic should cut across the triangle. L-shaped and U-shaped kitchens give the best triangles; a one-wall kitchen stretches it into a line, and a parallel (galley) kitchen works well if people do not walk through it.
Work centres in a kitchen
| Work centre | Main work done | What to keep there |
|---|---|---|
| Storage (refrigerator) centre | Receiving and storing food | Refrigerator, groceries, vegetable basket, tins for rice and dal |
| Preparation (mixing) centre | Cleaning, cutting, grinding, mixing, kneading | Knives, chopping board, mixer-grinder, measuring cups, rolling pin, flour |
| Cooking centre | Boiling, frying, pressure cooking | Stove, pressure cooker, kadai, ladles, oil, salt and the spice box (anjarai petti) |
| Cleaning (sink) centre | Washing food, vessels and hands; disposing of waste | Dish rack, scrubbers, detergent, waste bin, pots first filled with water |
| Serving centre | Dishing out and carrying food to the table | Serving bowls, plates, tumblers and trays, near the stove and the dining area |
Work heights from anthropometric measurements
| Body measurement | What it decides | Guideline |
|---|---|---|
| Standing elbow height | Counter height for standing work | A little below the elbow (roughly 7.5-10 cm lower) for light work such as cutting and mixing |
| Standing elbow height | Height for kneading, grinding, rolling | Lower than the main counter, so body weight can help the arms |
| Sitting elbow height and knee height | Seated work surface and knee space | Surface near seated elbow height, room for the knees, feet flat on the floor |
| Shoulder height and eye level | Shelves for everyday items | Keep daily-use items between hip and shoulder level, so there is no stretching or stooping |
| Overhead (vertical) reach | Highest shelf | No higher than the worker can reach without a stool; keep rarely used items there |
| Normal and maximum arm reach | Counter depth and placing of tools | Counters about 60 cm deep; often-used tools within the forearm's easy sweep |
Other features of an efficient kitchen
- Centres arranged in the order of work and joined by a continuous counter.
- Store each item at its point of first use: rice near the cooker, tea and sugar near the stove, knives at the preparation centre.
- Good daylight and a chimney or exhaust fan to remove smoke and heat.
- Smooth, easy-to-clean surfaces such as granite or stainless steel.
- The stove and gas cylinder placed safely, away from strong draughts and curtains.
- Enough floor space for two people to work, but no through traffic.
The same rules shape diet and hostel kitchens: separate preparation, cooking, tray-assembly and dishwashing areas laid out in the order of work, counters set to the cooks' elbow height, and supplies stored at the point of first use. A good layout cuts walking and delays and keeps raw and cooked food apart.
