One of the most common questions we get is:
“How big of a marquee do we actually need?”
The answer depends on far more than guest numbers alone.
When planning a private party or outdoor event, space planning plays a huge role in how comfortable and functional the event feels.
Here are a few things to consider before choosing your marquee size.
Start With Guest Numbers
The first thing to think about is whether guests will be:
- seated formally
- standing
- dining
- dancing
- moving between areas
A seated event naturally requires much more space than a casual standing party.

Think About Furniture
Tables and chairs can quickly reduce available room inside a marquee.
You may also need space for:
- buffet tables
- DJs
- dancefloors
- photo areas
- dessert tables
- bar setups
Many people underestimate how quickly space fills up once everything is installed.
Don’t Forget Guest Comfort
A marquee that is technically “full” doesn’t always feel comfortable.
For private parties especially, allowing enough room for guests to move freely creates a much better atmosphere overall.
This is particularly important during summer events where guests may be moving between indoor and outdoor areas.
Garden Shape Matters
Not every garden works perfectly with standard marquee sizes.
Things like trees, slopes, patios and fences can all affect layout options.
This is why bespoke marquee planning is often more effective than simply choosing a standard size online.
