Dining Table Size Calculator: What Fits Your Room?
Measure the floor space you have for dining and we will work out the largest standard table that fits, how many people it seats, and whether the table you have in mind will squeeze in. The number that matters most is not the table at all: it is the gap between the table edge and the wall, because that is where chairs pull out and people walk behind.
Your dining space
Measure wall to wall, or to the front of any sideboard, radiator or kitchen island that edges the dining area.
How the calculator works
It takes the clearance you choose off every side of the space, then picks the largest standard table size that fits what is left. Rectangular tables are checked in 20 cm steps from 100 to 300 cm long, at a depth of 90 cm where the room allows (100 cm for tables 240 cm and longer, and down to 75 cm in narrow rooms). Round tables run from 90 to 180 cm across, square ones from 80 to 160 cm.
Seating counts assume one diner at each end of a rectangular table plus as many along each side as the elbow-room setting allows. For round tables it divides the edge length by the space per person, which is why a 120 cm round table seats five comfortably but six at a squeeze.
Tips when the numbers are tight
- Push one side against a wall with a bench. A bench slides fully under the table, so that side needs almost no clearance, which suits a narrow London kitchen-diner.
- Go round in square rooms. A round table has no corners to walk around, so it feels easier to pass even at the same clearance.
- Buy an extending table. Size the room for the closed table you use every day and accept tight clearance on the few days a year it is fully open.
- Check the legs. A pedestal base lets you fit an extra chair that corner legs would block.
