# What Size Marquee Do I Need?
Guest count is the starting point, but it is not the whole answer. The right size marquee for your event depends on how you want to use the space — whether guests will be seated for a formal dinner, standing for a reception, or some combination of the two. It depends on whether you want a dance floor, and how large. It depends on where the bar will be, how the catering will be set up, and whether you need a separate entrance or staging area.
This guide explains the variables. The reckoner below does the arithmetic.
The key variables
Guest count and layout format
A seated dining layout uses considerably more space per person than a standing reception. The difference is significant:
| Format | Space per person (approx) |
|---|---|
| Seated dinner (round tables) | 1.8–2.2m² |
| Standing reception | 0.7–1.0m² |
| Mixed (seated dinner + standing reception area) | Calculate separately and add |
These figures include space for aisles, service runs, and the movement of guests and staff between tables. They do not include space for the dance floor, bar, catering area, or any other fixed element.
Dance floor
A dance floor for a wedding typically occupies 25–40m² depending on guest count and how much you expect it to be used. A practical rule of thumb: allow roughly 0.3m² of dance floor per guest, up to a ceiling of around 40m² for most wedding-scale events. A 6m × 5m (30m²) floor accommodates around 30–40 dancers comfortably at any given time, which is usually sufficient for 100 to 150 guests.
Catering setup
A professional catering operation within the marquee requires a defined working area. Depending on whether the caterer is using a dedicated kitchen tent (supplied separately) or working within the main structure, this is typically 15–25m² for a full service at 100 guests. Discuss the layout with your caterer before confirming the floor plan.
Bar
A fixed bar structure occupies 6–12m² depending on its size and configuration. Allow for a clear service area in front of it.
The structure type
Different structures use their floor area differently. A clear-span marquee has no internal poles, so the full floor is available. A traditional pole marquee has central poles that interrupt the layout and must be worked around — the usable floor area is slightly less than the overall dimensions suggest. The floor plan your marquee company produces will reflect this.

How to read a marquee specification
Marquee sizes are given as width × length in metres. A 12m × 18m structure has an internal floor area of 216m². For clear-span structures, that is the full usable area. For traditional pole structures, allow a small reduction for the poles and guy rope anchor points.
Common size benchmarks:
| Structure size | Seated dinner (approx) | Standing (approx) | Notes |
|---|---|---|---|
| 9m × 12m | 55–65 | 100 | Suitable for smaller weddings and parties |
| 12m × 18m | 100–120 | 170 | The most common wedding marquee size |
| 12m × 24m | 130–150 | 200 | Comfortable for 120–140 with dance floor |
| 15m × 24m | 160–190 | 260 | Large wedding or corporate event scale |
| 15m × 30m | 200–240 | 320+ | Very large events |
These figures assume a round-table layout with standard 5ft tables. Long-table layouts use space differently and may reduce seated capacity at a given footprint.
Why bigger is not always better
An oversized marquee can feel as uncomfortable as an undersized one. A marquee that is too large for its guest count will feel empty; the proportion between people and space matters as much as the raw square metreage.
The floor plan your marquee company produces is the definitive answer to the sizing question. It will show exactly how your specific guest count, table style, dance floor, and catering area fit within a given structure. Ask for one before you confirm the size.
Frequently asked questions
How much does adding a dance floor change the size I need?
A standard dance floor (6m × 5m, 30m²) at a 100-guest wedding effectively adds one more table cluster to the space you need. In practice, for events with a dance floor, we recommend going one size step up from what the dining layout alone would require — for example, a 12m × 21m rather than a 12m × 18m for 100 seated guests.
My venue has a restriction on the structure size. Can I still fit everyone in?
Possibly. The key question is the layout format: a standing reception or a more informal dinner arrangement uses space more efficiently than a formal seated dinner with round tables. Share your guest count, layout preference, and the available footprint with your marquee company and ask for a floor plan. The answer will be clear.
What if my guest count changes after I've confirmed the size?
A variation of plus or minus 10% rarely requires a change to the structure — it can usually be accommodated with a layout adjustment. A more significant change in guest count should be flagged to your marquee company as early as possible. Changes to the structure size late in the planning process are possible but carry a cost.
