> The tent size calculator works out how large an event tent or marquee you need for a wedding, party or conference from the number of guests and the seating style, plus bars, buffets, a stage and a dance floor, and suggests a standard tent size.

## Inputs

- Layout
- Guests
- Bars and buffet tables
- Waiter / service stations
- Stage or band area
- Dance floor

## Results

- Tent area needed
- Suggested tent

## Formula

```
Area = guests × space per guest (theatre 7, conference 8, cocktail 8, casual dining 10, formal dinner 12 ft²)
+ 100 ft² per bar or buffet table + 25 ft² per waiter station + stage + dance floor (≈ 3 ft² per dancing guest)
```

## Explanation

Rental companies size tents from the space each guest needs: standing cocktail parties need the least, seated formal dinners with round tables the most. Bars, buffets, a DJ or band stage and a dance floor all add to the footprint – and leave space for walkways and heaters.
