The right dining table size balances two things: enough table edge for everyone to eat in comfort, and enough room left over to pull out a chair and walk around the table. Plan on about 24 in of edge per person (22 in is the tight minimum), then check the table leaves at least 36 in of clearance to the nearest wall or furniture on every side. The calculator above does both for you, for rectangular, round, and square tables.
Dining table size by number of people
These rectangular dining table dimensions assume a table 36 to 42 in wide. A 60 inch (5 ft) table seats 6, while a 72 inch (6 ft) table seats 6 to 8 once you add a person at each end.
| Table length | In feet | Seats |
|---|---|---|
| 48 in | 4 ft | 4 |
| 60 in | 5 ft | 6 |
| 72 in | 6 ft | 6-8 |
| 96 in | 8 ft | 8-10 |
| 120 in | 10 ft | 10-12 |
Round dining table sizes (and how many they seat)
Round tables fit corners well and let everyone see each other. A 60 inch round dining table seats 6 to 8, and a 72 inch round dining table seats 8 to 10, so a round table is a space-friendly way to seat a crowd.
| Diameter | Seats |
|---|---|
| 36 in | 2-4 |
| 42 in | 4 |
| 48 in | 4-6 |
| 54 in | 5-6 |
| 60 in | 6-8 |
| 72 in | 8-10 |
| 84 in | 10-12 |
60 inch round dining table
A 60 inch round dining table (about 152 cm) seats 6 comfortably, and up to 8 if you tighten the elbow room. A round top seats more people per square foot than a rectangle and keeps the corners of a tight room clear. Plan on a room at least about 12 ft (3.7 m) across to leave 36 in of clearance all around. Add your room size above to confirm a 60 inch round table fits.
72 inch round dining table
A 72 inch round dining table (about 183 cm) seats 8 to 10, which makes it a popular choice for hosting without the length of a long rectangular table. It needs a fairly large room, roughly 13 to 14 ft (4 to 4.3 m) across, to keep a comfortable 36 in of clearance on every side. Enter your room dimensions in the calculator to see whether a 72 inch round table fits your space.
Square tables suit square rooms and smaller groups. Here is how many a square dining table seats by side length.
| Side length | Seats |
|---|---|
| 36 in | 4 |
| 48 in | 4-8 |
| 60 in | 8 |
| 72 in | 8-12 |
How much space do you need around a dining table?
Leave at least 36 in between every table edge and the nearest wall or furniture. That is the minimum to pull a chair out and sit down. For comfort, where people walk behind seated guests, aim for 42 to 48 in. To find the biggest table a room can take, subtract twice the clearance from each room dimension: a 12 by 14 ft room at 36 in clearance leaves room for a table up to about 96 by 72 in (8 by 6 ft). Enter your room size in the calculator to see this worked out for your space.
