A seated function needs 1.2–1.5 m² per guest, so 100 guests fit a 10m × 15m tent and 50 guests fit a 5m × 10m. The chart below turns any guest count into a tent size — including the dance-floor allowance that most wrong-size hires forget.
Tent size chart by guest count
| Guests (seated) | Area needed | Tent options |
|---|---|---|
| 20 | ~28 m² | 5m × 6m frame / 6m × 6m pole |
| 30 | ~42 m² | 5m × 9m frame / 5m × 10m stretch |
| 40 | ~56 m² | 5m × 12m / 7m × 9m |
| 50 | ~70 m² | 5m × 10m frame is the classic 50-seater |
| 60 | ~84 m² | 7m × 12m / 10m × 9m |
| 80 | ~112 m² | 7m × 15m / 10m × 12m stretch |
| 100 | ~140 m² | 10m × 15m frame or pole |
| 150 | ~210 m² | 10m × 21m / 15m × 15m |
| 200 | ~280 m² | 10m × 30m / 15m × 20m |
| 250 | ~350 m² | 15m × 24m |
| 300 | ~420 m² | 15m × 30m |
| 500 | ~700 m² | 20m × 40m or two joined marquees |
Add the dance floor before you book
A dance floor adds about 0.5 m² per guest — 100 guests with dancing need roughly 190 m², which moves the tent from 10m × 15m to 10m × 20m. The same shift applies to buffet tables, a stage or a bar corner: every function element is floor area. Undersizing is the most common hire mistake, and it shows the moment the first course clears.
Stretch tents seat fewer per square metre
Stretch fabric curves cost usable floor near the edges, so a stretch tent seats 10–15% fewer guests than a marquee of equal footprint — an 80-guest stretch function books 10m × 15m where a frame tent manages 100. Cocktail-style flips the maths: standing functions pack about 1 m² per guest, so the same 10m × 15m stretch tent holds 130 standing.
Seated, standing and buffet — three different numbers
| Function style | Per guest | Note |
|---|---|---|
| Banquet rounds (seated) | 1.4 m² | The default for weddings and dinners |
| Rows / ceremony seating | 1.0 m² | No tables, chairs in rows |
| Standing cocktail | 1.0 m² | Bar tables only |
| Seated + dance floor | 1.9 m² | Add the floor before choosing the tent |
| Seated + stage + buffet | 2.1 m² | Allow a full extra metre per guest |
From size to price
With the size fixed, how much it is to hire a tent gives the rand bands and the marquee pricing guide breaks down what drives the number. The type guides — marquee hire, stretch tent hire — settle which structure fits your site, and types of tents for hire compares all seven. Planning a wedding specifically? Sizing for the ceremony and reception together is covered in wedding tent hire.
For the single most-asked size question, we have a dedicated answer: how big of a tent do I need for 50 guests.
