Round Table Sizes: How Big Is a 6-Seater Round Table in cm?
Short answer: On a round table, the diameter determines how many people it seats. A 4-seater round table is 90-110 cm, a 6-seater round table is 120-130 cm, an 8-seater round table is 150-160 cm and a 10-seater round table is 180 cm in diameter. The height is 75-78 cm at every size. For an oval table, length is discussed instead of diameter: a 6-seater oval table is 180 × 100 cm, and an 8-seater oval table is 210-220 × 100-110 cm.
Round table size chart: how many people sit at each diameter?
On a round table the calculation is made not by side length but by circumference. The edge space needed for one person's plate and arms is 60 cm; dividing the circumference by 60 gives the capacity.
| Diameter | Circumference | Seated comfortably | Seated tightly |
|---|---|---|---|
| 90 cm | 283 cm | 4 people | 4 people |
| 100 cm | 314 cm | 4 people | 5 people |
| 110 cm | 346 cm | 4-5 people | 6 people |
| 120 cm | 377 cm | 6 people | 6 people |
| 130 cm | 408 cm | 6 people | 7 people |
| 150 cm | 471 cm | 7-8 people | 8 people |
| 160 cm | 503 cm | 8 people | 9 people |
| 180 cm | 565 cm | 9-10 people | 10 people |

The "seated tightly" column in the table is for holiday meals; everyone gets a seat, but elbows touch. If the same number of people sit down every evening, go by the comfortable column.
6-seater round table size: 120 or 130?
This is the most frequently asked size. A diameter of 120 cm is the lower limit for 6 people: the circumference is 377 cm, which gives 62 cm per person, a full fit. At a diameter of 130 cm the space per person rises to 68 cm, and a real area of 35-40 cm is left in the middle of the table for serving.
- 120 cm: Everyday use for 4 people, 6 people on busy days. The right size for a small kitchen and a corner of the living room.
- 130 cm: The right size for homes where 6 people sit regularly. You can place a pot or a salad bowl in the middle.
- 140 cm and above: Raises capacity to 7, but the centre of the table becomes an area that nobody can reach.
The type of base also matters a great deal at this size. On a table with a single central pedestal, 6 chairs can be arranged around the edge as you like. On a round table with four corner legs, chairs cannot go where the legs fall; even at a diameter of 130 cm it can in practice turn into a 4-seater table. On a round table, a central pedestal or a three-legged cross base always seats more people.
Extending round table: round when closed, oval when open
The biggest limit of a round table is its fixed capacity. The way to overcome this is an extension mechanism: the table stays round when closed, and when the extra leaf is fitted it becomes oval and lengthens. With real measurements at Selishome:
| Closed diameter | Open length | When closed | When open |
|---|---|---|---|
| 90 cm | 170 cm | 4 people | 6 people |
| 100 cm | 180 cm | 4 people | 6 people |
| 110 cm | 206 cm | 4-5 people | 8 people |
| 120 cm | 216 cm | 6 people | 8 people |
| 130 cm | 226 cm | 6 people | 8 people |
↔ Scroll the table sideways to see all of it.
These five rows are the diameter options of the Capi extending round table; the extra leaf is stored inside the table, so it takes no additional space. The same design is also found in the Panama extending round table. For those who set a longer table, there are models that open from a diameter of 120 cm up to 312 cm, such as the Golf extending round table; at this size a table for 12 can be set.
Point to note: The open size always grows into the room. When a table with a diameter of 130 cm extends to 226 cm, it overhangs 48 cm on each side; if in those two directions there is no room to pull the chairs back, the table in practice cannot be opened. We detailed the mechanism types in our article how many people does an extending dining table seat.
Oval table sizes: 6 and 8 seaters
An oval table is a rectangle with softened ends; its size is given as length × depth, not as diameter.
| People | Oval size | Seating arrangement |
|---|---|---|
| 4 people | 140 × 90 cm | 1 on each long side, 1 at each end |
| 6 people | 180 × 100 cm | 2 on each long side, 1 at each end |
| 8 people | 210-220 × 100-110 cm | 3 on each long side, 1 at each end |
| 10 people | 260 × 110 cm | 4 on each long side, 1 at each end |
↔ Scroll the table sideways to see all of it.
Because the ends of an oval table narrow, the two people at the head have a little less space than at a rectangular table of the same size. On the other hand, since there are no corners, there is no risk of bumping into them as you move around the room, and the table looks smaller to the eye.
How many m² should the room be for a round table?
The rule is simple: add 90 cm to the table's diameter in every direction. This allowance is for pulling the chair back (about 75 cm) and for passing behind it (15-20 cm).
- 120 cm diameter: 300 × 300 cm net area → about 9 m²
- 130 cm diameter: 310 × 310 cm → about 9.6 m²
- 150 cm diameter: 330 × 330 cm → about 10.9 m²
- 180 cm diameter: 360 × 360 cm → about 13 m²
The hidden advantage of a round table here is this: for the same number of people, a rectangular table needs a long rectangular area, while a round table needs a square one. If your living room has a square plan, or if you will place the table in the middle of the room, a round table almost always fits more efficiently. We explained which distances to keep when dividing a living room into dining and sitting areas in our article how to make a living room layout plan.
Round table or rectangular table?
A size chart alone does not decide it; the two shapes solve different problems.
- Narrow and long living room: A rectangular table sits parallel to the wall, while a round table blocks the passage.
- Square living room or kitchen corner: A round table gives equal distance on every side, with no bumping into corners.
- Home with small children: A round table has no sharp corners.
- Crowded and regular guests: A rectangular or extending oval table seats more people; a fixed round table reaches its limit at 8 people.
- Conversation: At a round table everyone can see everyone; at a long rectangular table the two ends cannot talk to each other.
For comparative sizes of all shapes by number of people, see our article dining table sizes; for rectangular sizes alone, see 6-seater table sizes and 8-seater table sizes. You can compare models in the dining table category and chairs in the chair category.
Choosing chairs for a round table
At a round table, chairs behave differently from those at a rectangular table: because they are arranged around the edge, their backs spread apart and their fronts come closer together. Look at three measurements:
- Chair width 45-50 cm. If 6 chairs are to be arranged around a table with a diameter of 120 cm, choose a slim-bodied chair of 45-47 cm.
- Prefer models without armrests. A chair with armrests cannot slide under a round table and reduces capacity by one person.
- Clear space under the tabletop at least 62 cm. On pedestal tables the base of the foot is wide; also take into account the place where you will put your feet.
We gathered the criteria beyond size, such as fabric, leg type and care, in our article how to choose a dining room chair.
Frequently Asked Questions
How many cm should a 6-seater round table be?
A diameter of 120-130 cm. 120 cm is the lower limit and seats 6 people fully; if 6 people sit there all the time, a diameter of 130 cm is more comfortable. The height is 75-78 cm at both sizes.
How many people does a 130 cm round table seat?
It seats 6 comfortably and 7 tightly. In an extending model, a diameter of 130 cm extends to 226 cm and turns into an 8-seater oval table.
How many cm is an 8-seater round table?
A diameter of 150 cm is the lower limit, and 160 cm is the comfortable size. Going above 160 cm does not increase capacity; it only enlarges the unreachable area in the middle.
What is the size of a 10-seater round table?
A diameter of 180 cm. At this size the circumference comes to 565 cm, which gives 56 cm per person. A fixed 180 cm table needs an area of about 13 m²; in most living rooms, a 180-200 cm extending oval table is a more workable solution.
How high is a round table from the floor?
The standard dining table height is 75-78 cm and does not change with the shape of the table. When the seat height of the chair is 45-48 cm, a gap of about 30 cm remains between the tabletop and the seat; this is the right measurement.
Is a round table suitable for a small living room?
In small living rooms with a square plan, yes: since it has no corners, it is easy to move around, and it seats the same number of people in a tidier area than a rectangular table. In narrow and long living rooms, on the other hand, it wastes space because it cannot be placed against the wall.
