What Size Round Table Seats Four
How much table edge each person needs, why 1000 mm is the usual answer, and when it is not.
Four people around a round table is the most common dining question there is, and the answer is almost always 1000 mm. Worth knowing why, because the reasoning also tells you when 1000 mm is wrong.
Start with one person
A place setting needs roughly 600 mm of table edge. That is a plate, a glass, cutlery either side and enough room that two people sitting next to each other are not touching elbows. Some sources say 550 mm, some say 650 mm. Use 600 mm and you will not be wrong often.
A setting also needs depth. From the edge inwards, allow about 400 mm for a plate, a glass and somewhere to put your forearms.
Now do the arithmetic
A round table gives you a circumference of roughly three times the diameter. A 1000 mm table has about 3140 mm of edge, which divided by 600 mm is five places on paper.
Paper is not dinner. Two things eat into it.
- Chairs are wider than place settings. A dining chair is typically 450 to 500 mm across, and on a circle the chairs fan outwards, so the space they need at the back is greater than the space their setting takes at the table edge.
- The middle disappears. If each setting is 400 mm deep, settings on opposite sides of a 1000 mm table leave a free circle of only about 200 mm in the centre. That is one small dish, or a bottle, not both.
So 1000 mm is four people with room to eat properly, and five or six when everybody understands what they signed up for. That is exactly what the description of our own Round Table says: four, comfortably.
When 1000 mm is the wrong number
Go smaller, around 800 to 900 mm, if the table is for two who occasionally host two more, if it lives in a kitchen corner, or if the room is under about 2.8 m across. A table that fits four but makes the room unusable is not seating four.
Go bigger, 1200 mm, if four people eat there every day with serving dishes in the middle, or if the table doubles as a desk and a homework surface, or if you want five at it regularly rather than occasionally.
Do not go bigger than 1200 mm for four unless the room demands it. On a large circle, the people opposite each other are far enough apart that conversation gets effortful and nobody can reach the middle.
The room, not just the table
Diameter is only half the planning. You need clearance around it.
- Allow at least 900 mm from the table edge to the nearest wall or furniture, so a chair can be pulled out and somebody can sit down.
- Allow 1200 mm where people walk behind a seated person.
So a 1000 mm table with 900 mm all around needs a clear area of about 2.8 m by 2.8 m. Write that number down before you measure the table, because the room is the thing that cannot be changed.
The base decides the seat count
Two tables with the same top can take different numbers of people.
Four legs at the edge means somebody ends up with a leg between their knees, and it means chairs cannot slide in anywhere they like. A central column leaves the whole perimeter clear, so four chairs can go anywhere on the circle, and a fifth can be squeezed in at Christmas without re-planning the table.
The trade is stability at the edge. A column base needs a wide enough foot, and on an uneven floor it needs to be levelled properly, which is why a single adjustable foot is worth more than it sounds.
Round or rectangular for four
For four people in a normal room, a circle usually wins, and for reasons that are practical rather than aesthetic.
- Everyone can see everyone. On a rectangle, two people are side by side and have to turn to talk. On a circle, nobody is beside anybody.
- No corners. Corners catch hips in a walkway and are the first thing a child meets at head height.
- The fifth person. On a circle with a central base, an extra chair goes anywhere. On a rectangle, the extra person sits at an end and the whole table has to be re-laid.
Rectangles win when the room is long and narrow, when the table has to sit against a wall, or when it doubles as a work surface and you want straight edges to lay things out on. Those are good reasons. Looking more formal is not.
Quick reference
| Diameter | Comfortable | At a push |
|---|---|---|
| 800 mm | 2 | 3 |
| 900 mm | 3 | 4 |
| 1000 mm | 4 | 5 to 6 |
| 1200 mm | 5 | 6 |
| 1400 mm | 6 | 8 |
Buy for the number of people who eat there on a normal Tuesday, not the number who come at New Year. The extra two people arrive once a year. The table is in your way every day.
Common questions
- Is a 900 mm round table big enough for four?
- For breakfast and laptops, yes. For four plates, four glasses, a board and something in the middle, it is tight. 900 mm gives each person about 700 mm of edge but only leaves a small free circle in the centre once place settings are laid.
- How many people fit around a 1200 mm round table?
- Five comfortably, six when everyone is friendly. The edge is there for six, but the centre space and the leg room between chairs run out before the circumference does.
- Does a round table seat more than a rectangular one?
- For the same footprint, usually yes, because nobody is sitting at a corner and a central base leaves the whole perimeter free. A 1000 mm round table and a 1000 by 1000 mm square take the same floor area, and the round one seats more people without anyone facing a table leg.
- What height should a dining table be?
- Around 740 mm is the convention, matched to a 450 mm seat. What matters more is the clearance under the top: measure to the underside and look for 250 to 300 mm above the seat.
