How the Event Tent Size Calculator (Guests and Tables) works
Choose a seating style, which sets the space per guest. Round tables with chairs need about 12 sq ft per guest.
Add the dance floor, bars, food stations and stage, then a margin for walking space.
The result is matched to the next standard tent size.
The formula
Worked example
Using the default values shown in the calculator:
| Guests | 100 |
|---|---|
| Seating style | Seated dinner at round tables (12 sq ft per guest) |
| Dance floor (sq ft) | 200 |
| Bars | 1 |
| Buffet or food stations | 1 |
| Stage or band (sq ft) | 100 |
| Extra room for walking and flow | 10 % |
- 100 guests × 12 + 200 + 40 + 60 + 100 = 1,600 sq ft; with 10% flow room the area needed is 1,760 sq ft.
- The next standard tent is 30 × 60 ft (1,800 sq ft), with 40 sq ft to spare.
Result:
| Area needed (sq ft) | 1,760 |
|---|---|
| Tent size to rent | 30 × 60 ft |
| Tent area (sq ft) | 1,800 |
| Spare space (sq ft) | 40 |
| Area needed (sq m) | 164 |
