6×3 vs 9×3 vs 6×6 Marquee: Which Size Marquee to Buy

Choose the 6x3m for smaller backyard groups, the 9x3m for around 45 standing or 18 dining guests, and the 6x6m for about 60 standing or 24 dining. The 3x12m covers the same 36 square metres as an open-sided strip but is currently sold out. If you need more dining space or a wedding-style aluminium frame, compare the 10x5m, or step up to the 12x6m at 72 square metres.

If you're trying to work out which size marquee to buy, the choice almost always comes down to the three most popular footprints we sell: the 6x3m ($249), the 9x3m ($349) and the 6x6m ($949). The 6x3m and 9x3m share the same handy 3m depth, so they tuck neatly down a driveway or along a fence line, while the 6x6m doubles the depth for a square, fully enclosed room. The more floor area, the more people you can comfortably fit. This guide breaks down who each one is for, so you buy once and get it right.

The quick answer

Think about your biggest gathering, not your average one, you want the marquee that still works when everyone turns up. Here's how the three compare side by side:

Marquee Footprint Area Standing Seated (rows) Seated dining
6x3m Marquee 6x3m 18m² ~30 ~20 ~12
9x3m Marquee 9x3m 27m² ~45 ~30 ~18
6x6m Marquee 6x6m 36m² ~60 ~40 ~24
8x4m Marquee8x4m32m²~50~35~20
10x5m Marquee10x5m50m²~80~55~33

Those numbers are based on the room each guest actually needs: about 0.6m² standing, 0.9m² seated in rows and 1.5m² for a sit-down meal. Add roughly 25% on top if you also want a dance floor, a bar or a buffet table under cover.

6x3m, the backyard all-rounder

The 6x3m is the size most people actually need and don't realise it. At 18m² it covers a backyard birthday, a long table of 10-12 for a sit-down lunch, or a crowd of up to 30 mingling with drinks. It's light enough for two people to set up, and small enough to store in the shed without it taking over. If your get-togethers are family-sized and you want one marquee that earns its keep year-round, start here.

9x3m, the step up for proper parties

The 9x3m is the one to pick when "a few people over" turns into "a proper party." That extra 3m of length takes you from ~12 diners to ~18, or up to 45 standing, enough for an engagement do, a milestone birthday, or a market stall with room to move. It's the natural choice if the 6x3m feels like it'll be a squeeze on your busiest day, without jumping to a much bigger footprint.

6x6m, maximum cover, one marquee

The 6x6m marquee ($949) is for when you genuinely need to get a crowd under cover. At 36m² it seats around 24 for dinner, 40 in rows, or handles up to 60 standing, community events, big family Christmases, club functions or an engagement party, all in one fully enclosed square room.

How to choose between them

  • Count your biggest day, then size up. If you're regularly on the line between two sizes, the larger one is the one you won't regret.
  • Dining needs far more room than standing. A 6x3m fits ~30 standing but only ~12 at tables, if it's always sit-down meals, jump a size.
  • Weather changes the maths. If rain could push everyone under cover at once, plan for everyone seated, not just the standing number.
  • Got more than ~60 guests? Look at the 10x5m wedding marquee (50m²), or step up to the 12x6m grand marquee (72m², up to 120 standing or ~48 seated dining), for large weddings and events. You can also run two marquees side by side.
  • Want a wider, fully enclosed room? The 8x4m Wedding & Party Marquee (32m², ~50 standing, ~20 seated dining, $899) gives you cathedral-style window walls and a proper enclosed space, a solid step up from a gazebo without the big-marquee price.

Smaller crowd? The 3x3m marquee ($199) covers up to 10 standing.

By the numbers

  • 6 sq ft (about 0.56 m2) per person standing. For a standing crowd, allow roughly six square feet of floor space per guest so people can mingle in comfort. Source: Social Tables (Cvent) (2024).
  • 11 to 12 sq ft (about 1.0 to 1.1 m2) per seated dining guest. A seated plated dinner at round tables needs a bit more room, around eleven to twelve square feet per guest. Source: Social Tables (Cvent) (2024).
  • 4.5 sq ft (about 0.42 m2) per dancer. Adding a dance floor, allow roughly four and a half square feet of space for each dancing guest. Source: Social Tables (Cvent) (2024).

Common questions

What is the difference between a 6x3, 9x3 and 6x6 marquee?

The 6x3m and 9x3m are both 3m deep and only the length changes, while the 6x6m is a square room. The 6x3m gives 18m² (~30 standing / ~12 dining), the 9x3m gives 27m² (~45 standing / ~18 dining), and the 6x6m gives 36m² (~60 standing / ~24 dining).

Which size marquee should I buy for a backyard party?

For most backyard parties the 6x3m marquee (18m²) is the sweet spot, it suits a long table for 10-12 or up to 30 guests standing. Step up to the 9x3m if your busiest day pushes past that.
