This marquee hire size guide: for a seated dinner allow 1.4 square metres per guest, then add a dance floor at 0.2 sqm per guest and 15 to 25 sqm for a bar. What size marquee do you need for 100 guests? About 160 sqm with dancing: a 12m × 15m to 12m × 18m frame marquee. Standing receptions need less than half the seated area.
Marquee capacity guide: size classes at a glance
| Guests | Size class | Typical footprint | Territory |
|---|---|---|---|
| Up to 60 | 20m-class | 9m × 12m | garden weddings, big birthdays |
| 60–120 | 30m-class | 12m × 18m | the classic wedding size |
| 120–250 | 40m-class | 12m × 30m or 15m × 25m | large weddings, corporate dinners |
| 250–500 | 50m-class | 20m × 35m | balls, big corporate events |
| 500+ | 60m-class+ | 25m × 45m+ | multi-structure territory |
Width is the real decision
Marquees come in fixed widths (6, 9, 12, 15, 20 metres and up) and grow in length by bay. Width sets the feel: 9m seats a narrow dinner, 12m fits rounds with a comfortable aisle, 15m and up gives you zones: dining here, dancing there, lounge in the corner. Length is cheap to add; width changes the product.
Ground matters as much as area: read the full marquee hire guide for frame vs pole vs stretch, lining, flooring and access, or check the trackway estimator if your site is a field. Once the size is settled, work out how many toilets it needs: the two numbers are usually booked from the same supplier conversation.
The same guest count also sets table and chair quantities, so it is worth working those out while the floor plan is still fresh: one round per 8 seated guests, one chair per guest plus 5 percent spares.
Marquee sizing: quick answers
What size marquee do I need for 100 guests seated?
Around 140 sqm at 1.4 sqm per guest: typically a 12m × 12m to 12m × 18m frame marquee once you add a dance floor and bar. A 9m-wide structure works for a tighter dinner without dancing.
What is a marquee hire size guide?
A marquee hire size guide is a table matching guest numbers to floor area and structure width: the same sums a marquee company runs on a site visit, multiplying guests by a space-per-person ratio (1.4 sqm seated, 0.9 sqm theatre, 0.6 sqm standing), adding extras like a dance floor or bar, then matching the total to the nearest buildable marquee width. The size-class table above is that guide; the calculator gives the exact figure for your own guest count.
What size marquee for 60 guests?
Roughly 85 sqm seated with room to move: a 9m × 9m or 9m × 12m frame marquee is the usual answer, stepping up if you want a dance floor inside rather than a separate space.
How much space per person in a marquee?
Use 1.4 sqm per guest for a seated dinner with service space, 0.9 sqm for theatre-style seating, and 0.6 sqm for a standing reception. Add the dance floor, bar and stage on top of the per-guest number.
Do these sizes include the dance floor and bar?
The per-guest ratios cover dining tables and circulation. A dance floor adds about 0.2 sqm per guest, a bar zone 15 to 25 sqm, a stage 20 to 50 sqm: our calculator adds the dance floor when you toggle it.
What about the space around the marquee?
Frame marquees can build tight to boundaries, but traditional pole marquees need roughly 3m of pegging clearance on every side. Caterers also want their tent annexed to one end, so leave a service side.
What are the standard marquee sizes?
Width comes in fixed steps: 6m, 9m, 12m, 15m, 20m and up, with length added by the bay so two marquees of the same width can still differ a lot in floor area. The size-class table above turns those widths into guest capacity: 20m-class suits up to 60 guests, 30m-class the classic 60 to 120 wedding size, stepping up through 40m, 50m and 60m-class for larger weddings, balls and multi-structure events.
