Choosing the right size marquee is one of the most common questions we're asked at Eclipse Marquee Hire — and it's one of the easiest things to get wrong. Too small, and your guests are crammed in with nowhere for a bar or dance floor. Too large, and you're paying for empty space you didn't need. Whether you're planning a wedding marquee, a garden party, a corporate event, or a festival structure in Northamptonshire, this guide will walk you through exactly how to size it correctly.
The Golden Rule of Marquee Sizing
As a general rule of thumb, allow 1.5-2 square metres per guest for a seated dinner, or around 1 square metre per guest for a standing reception. This is the starting point we use for every quote, before adjusting for your specific layout, catering style, and any extras like a dance floor or bar.
Marquee Sizes & Guest Capacity
Here's a general capacity guide based on the marquees we supply most often across Rushden, Northampton, Kettering, Wellingborough, Corby, Bedford and Milton Keynes. Our smallest marquee is 6m x 6m — we don't go any smaller than this, as anything less rarely works well once you factor in tables, walkways and weather protection.
| Guests (Seated) | Marquee Size | Typical Use |
|---|---|---|
| Up to 30 | 6m x 6m – 6m x 9m | Intimate garden parties, small family gatherings |
| Up to 60 | 6m x 12m | Milestone birthdays, christenings |
| Up to 90 | 9m x 15m | Most popular wedding size |
| Up to 108 | 9m x 18m | Weddings with a generous dance floor |
| Up to 144 | 9m x 24m | Larger weddings, corporate functions |
| 150-200+ | Custom or linked structures | Festivals, large corporate events |
Sizing a Wedding Marquee
Wedding marquee hire is where sizing questions come up most. Beyond guest numbers, think about whether you want a separate area for the ceremony, a drinks reception space (a pagoda entrance works brilliantly for this), and enough room for a proper dance floor once the meal is cleared. Most Northamptonshire couples we work with go for a 9m x 15m or 9m x 18m marquee — big enough to feel spacious, without overwhelming a garden or field.
Sizing for Parties & Celebrations
Birthday parties, anniversaries, garden parties and baby showers tend to need less space than a formal wedding dinner, since layouts are often more relaxed with a mix of seating and standing areas. A 6m x 9m or 6m x 12m marquee comfortably covers most private celebrations of 30-60 guests.
Sizing for Corporate Events
Corporate marquee hire varies enormously depending on the format — a seated awards dinner needs significantly more space per head than a standing product launch or exhibition. We always recommend a free site visit for corporate bookings so we can plan around your exact format, branding requirements, and any AV or catering equipment.
Sizing for Festivals & Outdoor Events
Festival and outdoor event structures are a different challenge altogether — often a mix of smaller bar tents, vendor stalls, and a larger stage cover or hospitality marquee, rather than one single structure. We size these based on your site plan and expected footfall rather than a simple per-guest calculation.
Don't Forget Ground Conditions
The size and shape of marquee that works best isn't just about guest numbers — sloped gardens, uneven fields, and tight access can all affect what's realistically possible on your site. This is exactly why we offer a free site visit with every enquiry, so we can advise on the ideal size and layout before you commit to anything.
