Seated vs standing — why it matters
The biggest factor in "how many guests fit" isn't the marquee — it's what you're doing inside it. A seated wedding breakfast with round tables, chairs and a dance floor needs far more space per person than a standing drinks reception.
As a general planning rule: seated dining needs roughly 1.5m² per guest once you include tables, chairs and space to move. A standing reception needs roughly 0.6-0.7m² per guest. These are industry-standard estimates, not specific to any one supplier — treat them as a starting point for planning, not a guarantee.
Approximate capacity by marquee size
Based on the standard planning ratios above. Your exact capacity will vary depending on your furniture choice, whether you want a dance floor, staging, or a bar area — use this as a guide, then confirm specifics with our calculator.
| Marquee Size | Approx. Footprint | Seated Dining | Standing Reception |
|---|---|---|---|
| 3m × 6m | 18m² | ~20 guests | ~28 guests |
| 3m × 9m | 27m² | ~30 guests | ~42 guests |
| 4m × 6m | 24m² | ~28 guests | ~38 guests |
| 4m × 8m | 32m² | ~35 guests | ~50 guests |
| 4m × 10m | 40m² | ~45 guests | ~65 guests |
| 6m × 8m | 48m² | ~55 guests | ~80 guests |
| 6m × 10m | 60m² | ~70 guests | ~100 guests |
| 6m × 12m | 72m² | ~85 guests | ~120 guests |
What else affects the fit
- Dance floor — reduces usable dining space; worth factoring in before finalising guest count.
- Top table or stage — Mehndi and Nikkah ceremonies in particular need a dedicated stage area on top of guest seating.
- Bar or drinks area — a separate standing zone takes space away from the seated footprint.
- Garden shape — an irregular or sloped garden may limit which marquee dimensions are practical, regardless of guest count.
- Planning permission — most private events don't need it, but a few situations do. See our planning permission guide.
Common questions
How many guests fit in a marquee?
It depends on the footprint and whether guests are seated or standing. As a rough guide, seated dining needs around 1.5m² per guest, standing reception around 0.6-0.7m².
Are these capacity figures exact?
No — they're a planning guide, not a guarantee. Your actual capacity depends on furniture, dance floor, staging and venue shape. Use the calculator or get in touch for a figure specific to your layout.
What size marquee do I need for a wedding?
Most residential wedding receptions of 50-80 seated guests fit comfortably in a 6m-wide marquee of 8-10m length. Smaller celebrations of 20-40 guests often work well in a 4m-wide marquee.
What size marquee do I need for 100 guests?
For 100 seated guests, a 6m-wide marquee of around 12m length gives roughly 72m² — enough for full dining, though tight for a dance floor too. For 100 standing guests, 6m x 10m is usually sufficient. Get in touch with your exact layout for a precise recommendation.
Is there a marquee seating guide for different table shapes?
Yes — table capacity varies by type: a 5ft round table seats 10, a 6ft round seats 12, and a 6ft trestle table seats 8 on its own (3 along each long side, 1 at each end). If trestle tables are joined together in a row, the short ends where they connect aren't usable, so each joined table effectively seats 6 rather than 8. Round tables generally give you more guests per table in a compact footprint; trestles create the long "banquet" look but seat fewer per table once joined.
