How much room does a dining table really need?

The table is the small part. The chairs pulling out and someone walking behind them is what decides the room.

People size a dining room by the table and are then surprised that it does not work. The table is the small part.

The numbers

Table edge to wall — chair pulls out	760 mm
Table edge to wall — someone walks behind	1100 mm
Per person at the table	600 mm of edge
Table depth, seating both sides	900 mm

760 mm lets a chair slide back far enough to stand up. It does not let anyone pass behind the person sitting there. For that you need 1100.

Work it out properly

A 900 × 1500 mm table seating six, with 1100 mm all round for circulation:

900 + 1100 + 1100 = 3100 mm one way 1500 + 1100 + 1100 = 3700 mm the other

A 3.1 × 3.7 m room, just for dining. That is bigger than most people picture, and it is why dining so often ends up borrowing space from the hall.

Borrowing is a legitimate answer. Pretending you did not is not. On the house we drew, the dining borrows its clearance from the hall — the cross walls were deliberately removed so hall, spine and dining read as one space — and that is written on the drawing rather than hidden.

Round tables

A round table seats more people in less width, because nobody is at a corner. A 900 mm diameter seats four comfortably; 1200 mm seats six at a squeeze.

They are also easier in a tight room: no corners to catch a hip on, and the clearance you need is the same in every direction rather than varying.

The wall behind the chair

If one side of the table is against a wall and nobody ever walks behind it, 760 mm is enough on that side. Use the asymmetry — put the table's tight side against the wall and keep the full 1100 mm on the side people actually pass along.

That single move is often the difference between a dining area that fits and one that does not.

Where it sits

Between the kitchen and the living area. Carrying food from the kitchen across a living room to a dining table is a route you will walk several times a day for the life of the house, and it should be short.

Kitchen → dining → living, in that order.
