How wide a table each number of seats needs, and how much floor the whole set eats once chairs pull out. Start from the table below, then check it against your room.
A dining table is easy to size on paper and easy to get wrong in a room. The table itself fits; the problem is the ring of space around it, because every chair has to slide back about 60 cm before anyone can sit, and someone still has to walk behind. Start from the table below to pick the tabletop, then use the second table to check the whole set clears the room.
Table size by number of seats
The rule underneath every row is simple: each person needs about 60 cm of table edge for a comfortable place setting, plus depth for plates in the middle. These are working sizes, not showroom extremes.
| Seats | Rectangular size | Good for |
|---|---|---|
| 2 | 70 by 70 cm | A bistro table, one wall, a small kitchen |
| 4 | 120 by 80 cm | The everyday size for a couple or small family |
| 6 | 180 by 90 cm | Regular guests, a dedicated dining zone |
| 8 | 240 by 100 cm | A long table for a full house |
How much floor the whole set needs
This is the number people forget. A table is not the footprint you plan around; the footprint is the table plus 100 to 120 cm on every side, because a chair pulls out about 60 cm and a person passing behind it needs another 60 cm. Add the table size to twice that clearance to get the floor the set occupies.
| Table | Add per side | Total floor area |
|---|---|---|
| 4-seat, 120 by 80 cm | 100 to 120 cm | 3.2 by 2.8 m to 3.6 by 3.2 m |
| 6-seat, 180 by 90 cm | 100 to 120 cm | 3.8 by 2.9 m to 4.2 by 3.3 m |
| 8-seat, 240 by 100 cm | 100 to 120 cm | 4.4 by 3.0 m to 4.8 by 3.4 m |
If the wall behind a chair is a dead end (nobody walks there), you can drop that side to 75 cm: enough to pull the chair out and stand, just not to pass behind. Only shave the sides that truly have no traffic. The full set of clearances is in the furniture clearance and walkway spacing guide.
Round or rectangular
Shape changes how many people fit and how the table sits in the room. Rectangular tables run along a wall and scale cleanly with length. Round tables seat people more sociably and lose the hard corners, which helps in a tight or square room, but they eat a bigger circle of floor for the same headcount.
- Round tables seat 4 at about 100 cm across, 5 to 6 at about 120 cm, 8 at about 150 cm.
- A round table with no corners is safer in a walkway and reads calmer in a small square room.
- Rectangular tables use a long wall efficiently and extend to seat more with leaves.
- For 6 or more in a narrow room, rectangular almost always wins; a round table for 8 needs a 3.5 m clear circle.
Sizing a dining zone inside a larger room is its own problem: see the open-plan living dining layout guide for splitting the space without walls. The 4x6 studio apartment layout shows a table for two fitted next to a kitchen line, and the furniture dimensions guide has chair and sideboard sizes.
Common questions
- How much space do you need around a dining table?
- About 100 to 120 cm on every side you walk or sit at. A chair pulls out roughly 60 cm, and a person passing behind it needs another 60 cm. On a side against a dead-end wall you can drop to 75 cm, enough to stand but not to pass.
- What size table seats 6?
- A rectangular table around 180 by 90 cm, giving each person about 60 cm of edge. A round table for 6 needs roughly 120 to 135 cm across. Both want a floor area near 4 by 3 m once you add pull-out space.
- How wide should a dining table be per person?
- Allow about 60 cm of table edge per place setting, and at least 30 cm of depth toward the middle for plates and glasses. Below 55 cm per person the settings start to overlap and elbows collide.
- Is a round or rectangular table better for a small room?
- A round table for 4, at about 100 cm across, often suits a small square room best: no corners to catch a walkway and it seats people closer. For 6 or more, or a narrow room, a rectangular table along a wall uses the space more efficiently.
