Quick answer: Allow about 60 cm of table width per person. A rectangular table for 4 needs roughly 120–150 cm of length, for 6 around 180–210 cm, and for 8 around 240–270 cm. Round tables seat fewer for the same diameter. Whatever the size, leave at least 90 cm of clearance between the table edge and the nearest wall so chairs can pull out.
Dining table size chart
| Seats | Rectangular length (cm) | Round diameter (cm) |
|---|---|---|
| 2 | 70–90 | 70–90 |
| 4 | 120–150 | 100–120 |
| 6 | 180–210 | 140–150 |
| 8 | 240–270 | 160–180 |
| 10 | 300–330 | — (rectangular better) |
These assume standard chair widths. Tables with a central pedestal seat slightly more flexibly than those with corner legs.
Don't forget the clearance
Table size is only half the equation — you also need room to sit down and walk around. Leave a minimum of 90 cm (ideally 100–120 cm) between each table edge and the wall or nearest furniture. To find your maximum table size, measure your dining area and subtract 180 cm from both the length and the width.
Round vs rectangular
Round tables suit smaller or square rooms and make conversation easier, but seat fewer people per square metre. Rectangular tables fit narrow rooms and scale better for larger groups. Tight on space? An extendable or foldable table gives you everyday compactness with capacity for guests.
