UK Marquee Size Guide: How Big a Marquee for Your Guests
General answer
UK marquee industry densities: 1.2–1.5 m² per guest for seated dining, 0.5–0.8 m² standing, ~1 m² theatre-style. A 100-guest wedding with dining and dancing typically needs 90–150 m² — around a 10×15 m marquee — with the dance floor, bar and catering area added as separate blocks (~25–30 m²). A dance floor inside the same footprint cuts seating capacity 20–30%.
Your numbers below — the calculator personalizes this.
Comfort planning density from rental/marquee industry charts (10–12 ft² ≈ 1.2–1.5 m² per seated guest). Add dance floor, bar, buffet and stage as separate blocks — they are not in per-person math.
Fire-code ceiling for comparison: the legal maximum density is far tighter than comfort — the posted occupant load is a legal maximum, never a planning target.
The marquee decision chain
A UK marquee wedding is really five linked decisions: size (this page), fire safety and capacity duty (the responsible-person rules), toilets (council ratio table), alcohol licensing (a TEN if you sell drinks on unlicensed land), and power. Marquee firms quote ex-VAT surprisingly often because their usual clients are businesses — confirm every quote includes 20% VAT before comparing.
Assumptions
- UK marquee-firm sizing guides (tier-3), metric; consistent across suppliers.
- Clearspan marquees; traditional pole marquees lose usable edge space.
What changes this answer
- Seated dining vs standing reception — nearly 3× density difference.
- Winter events need walkway covers and heating space.
- Ground conditions: sloped or soft ground reduces usable area.
