Dining table size, seats and room.
Two numbers decide it: the table edge each person needs, and the space behind their chair. Both come from the kitchen designers’ own planning guidelines.
The short answer
Give every diner 24 in (610 mm) of table edge, and keep 36 in (914 mm) from the table edge to the wall wherever someone has to squeeze past a seated person, 44 in (1118 mm) where they should walk past normally. Both figures are from the National Kitchen & Bath Association’s planning guidelines (Guidelines 9 and 8).
Seats and the room around them
Seats: two long sides at 24 in each, plus one at each end when the table is at least 24 in wide. Room: the table plus 36 in on every side, the edge-past clearance. Round tables: the edge length π × diameter, divided by 24 in.
| Table | Seats at 24 in | Room for 36 in all round |
|---|---|---|
| 60 × 36 in 152 × 91 cm | 6 | 11 ft × 9 ft 3.35 × 2.74 m |
| 72 × 36 in 183 × 91 cm | 8 | 12 ft × 9 ft 3.66 × 2.74 m |
| 84 × 40 in 213 × 102 cm | 8 | 13 ft × 9 ft 4 in 3.96 × 2.85 m |
| 96 × 40 in 244 × 102 cm | 10 | 14 ft × 9 ft 4 in 4.27 × 2.85 m |
| 108 × 42 in 274 × 107 cm | 10 | 15 ft × 9 ft 6 in 4.57 × 2.90 m |
| 36 in round 91 cm | 4 | 9 ft square 2.74 m |
| 42 in round 107 cm | 5 | 9 ft 6 in square 2.90 m |
| 48 in round 122 cm | 6 | 10 ft square 3.05 m |
| 54 in round 137 cm | 7 | 10 ft 6 in square 3.20 m |
| 60 in round 152 cm | 7 | 11 ft square 3.35 m |
| 72 in round 183 cm | 9 | 12 ft square 3.66 m |
Seat counts are the minimum spacing; comfortable dining chairs and armchairs need more than 24 in. Clearances are planning guidelines, not code.
Behind the chairs
- 32 in · 813 mmTable edge to wall when nobody passes behind a seated diner (NKBA 8).
- 36 in · 914 mmTo edge past a seated diner (NKBA 8a).
- 44 in · 1118 mmTo walk past a seated diner (NKBA 8b).
- 60 in · 1524 mmFor a wheelchair to pass behind a seated diner (NKBA 8, access standard).
A worked example: the flat on our home page
Its dining table is 1.60 m (63 in) long and 0.95 m (37 in) wide. At 24 in per diner the long sides take 2 each, 4 in all, which is what the plan shows; at 37 in wide each end could take 1 more. Behind the chairs there is 1.45 m (57 in) to the floor lamp on one side and 2.84 m (112 in) to the wall on the other, both more than the 44 in (1118 mm) needed to walk past. One end of the table is 0.09 m (4 in) from the wall, so that end cannot take a chair; the other has 2.60 m (102 in) of floor, room for a fifth.
The rug under it
A rug under a dining table should be about 36 in (91 cm) longer and wider than the table, so chairs stay on it when pulled out. The rug size guide works it through.

Dining tables, answered.
How many people fit at a 60 in (152 cm) table?
Along its sides, 2 per side at 24 in (610 mm) each, so 4; a table at least 24 in wide takes one more at each end, so 6.
How much space do you need around a dining table?
From the table edge to the wall: 32 in (813 mm) if nobody walks behind the chairs, 36 in (914 mm) to edge past, 44 in (1118 mm) to walk past (NKBA Guideline 8).
How many people fit at a 48 in round table?
Its edge is π × 48 ≈ 151 in, which at 24 in per diner is 6 seats.
Is 24 inches per person enough?
It is the minimum the NKBA plans for at a 30 in high table; armchairs and wider chairs need more.
