What Size Marquee Do I Need for 50, 100 or 150 Guests?

The single most common question we get is "what size marquee do I need?" The answer depends on your guest count and what they'll be doing, standing with drinks, sitting in rows, or sitting down to dinner. This guide gives you a straight answer for 50, 100 and 150 guests, plus the simple formula to size any number in between.

The quick formula

Allow roughly:

  • 0.6m² per guest standing (cocktail style)
  • 0.9m² per guest seated in rows (ceremony style)
  • 1.5m² per guest for seated dining (reception style)

Then add about 25% if you want a dance floor, bar, buffet or stage. Always size for your worst-weather plan, the day everyone needs to be under cover at once, not just a sunny afternoon.

Marquee size for 50 guests

For 50 standing you need ~30m²; for 50 seated dining you need ~75m². A 3x12m event shelter (36m²) or two 3x9m marquees handle a standing party of 50 well. For a seated dinner of 50, step up to the 10x5m wedding marquee (50m²), which gives everyone a chair and room to move.

Marquee size for 100 guests

One hundred guests standing needs ~60m²; seated dining needs ~150m². The honest answer here is that 100 seated diners is a two-marquee job, two 10x5m units joined or placed side by side, or one 10x5m for dining plus a 3x9m for the bar and food. For a standing/cocktail 100, a single 10x5m plus a 3x9m covers it comfortably.

Marquee size for 150 guests

One hundred and fifty standing needs ~90m²; seated dining needs ~225m². Plan for multiple marquees, typically two to three 10x5m units, configured around a central space. Because you own the marquees rather than hiring, scaling up for a big day and reusing them afterwards is far cheaper than paying hire rates on a large structure.

At-a-glance size table

Marquee Area Standing Seated (rows) Dining
3x6m Marquee 18m² ~30 ~20 ~12
3x9m Marquee 27m² ~45 ~30 ~18
3x12m Event Shelter 36m² ~60 ~40 ~24
10x5m Wedding Marquee 50m² ~80+ ~55 ~33

Don't forget the extras

A dance floor adds roughly 12 to 15m² for a small event and more for a big one. A buffet or grazing table needs a few square metres of its own. A bar, a cake table, a DJ, all eat into the floor. When in doubt, size up: a slightly bigger marquee feels relaxed, a too-small one feels cramped on the day.

Common questions

What size marquee do I need for 50 guests?

For 50 standing you need ~30m² (a 3×12m event shelter at 36m² works well). For a seated dinner of 50 you need ~75m², so step up to a 10×5m marquee (50m²) plus a second marquee.

What size marquee for 100 guests?

One hundred standing needs ~60m² (a 10×5m plus a 3×9m covers it). One hundred seated diners is a two-marquee job, two 10×5m units, or one for dining and one for the bar and food.

How much space do you need per guest under a marquee?

Allow about 0.6m² per standing guest, 0.9m² seated in rows and 1.5m² for seated dining, then add roughly 25% for a dance floor, bar or buffet.
