Capacity calculator
How many tables fit in your space
Enter the room or tent, pick a table and a spacing rule, and see the count. The same geometry runs in the planner, so the two never disagree.
What the spacing rule means
The gap is measured edge to edge between table tops, not centre to centre. Two guests sitting back to back at neighbouring tables need room for both chairs plus a path between them, which is where 54 inches comes from: about 18 inches of chair each way, plus a walkway.
At 54 inches a server can pass but two people cannot pass each other. At 60 inches they can. Venues that run plated service usually ask for 60.
Round tables are laid out whichever way fits more. Staggered rows interleave, so they sit closer front to back, but the half-pitch shift can cost a whole column on a narrow floor. A 60 by 90 ft room takes 54 sixty-inch rounds in straight rows and 61 staggered. A 30 by 45 ft room takes 15 straight and only 13 staggered. The calculator tries both and reports the better one.

Common answers
| Space | 60 in rounds at 60 in | Seats | Rows |
|---|---|---|---|
| 20 by 30 ft | 6 | 48 | Straight |
| 30 by 45 ft | 15 | 120 | Straight |
| 40 by 60 ft | 25 | 200 | Staggered |
| 40 by 80 ft | 32 | 256 | Straight |
| 60 by 90 ft | 55 | 440 | Staggered |
Counts assume a clear rectangle. A pillar, a bar or a dance floor takes tables out, which is what the planner is for. Values are common venue guidance and your own settings, not a code review.
