Round conference table sizes
A round table seats its circumference divided by the space per person. There is no head of the table, which suits smaller, equal-sided conversations — and caps how many people fit before the diameter outgrows the room.

The round rule
Seats = circumference ÷ space per person, rounded down (Paul Downs seating guide). That reproduces the published checks used across this site: at 36 inches a 48-inch round seats four and a 96-inch round seats eight. Because the diameter grows with every added seat, rounds are practical roughly from four to twelve people; beyond that, a rectangle or boat shape seats more people in less room.
Choosing a diameter
- 4–6 people: a 48–72 inch round keeps everyone within easy conversation distance.
- 8–10 people: allow 96–120 inches at comfortable spacing, and check the square room it needs.
- 12 people: the top of the practical range — compare a rectangle in the planner before committing.
Test any diameter in your room with the Plan links above, or compare against the dimensions guide and size chart by seats.
Conference table sizing, answered
How many people fit at a 72-inch round table?
At 36 inches per person, a 72-inch round seats 6: its circumference divided by the space per person (Paul Downs).
What diameter round table seats 10 people?
At 36 inches per person, allow a 120-inch (10 ft) diameter; at 30 inches per person, 96 inches.
Round or rectangle for a small meeting room?
Rectangles seat the most people per foot. Round tables seat their circumference divided by the space per person, and suit smaller, equal-sided conversations where nobody sits at a head.
How much room does a round table need?
Add 42–48 inches of clearance on every side of the diameter; the chart shows the minimum square room at 36 inches per person.
