What Size Bouncy Castle Do I Need?

Choosing the right size bouncy castle is one of the most important parts of planning your event. The correct size depends on where the inflatable will be set up, who will be using it, and how much clear space is available. This guide explains what to think about before you book.

Measure the available space

Start by measuring the full area where the bouncy castle will go, not just the grass or floor space. You need room for the inflatable itself plus clear space around it for safe access. As a general rule, allow extra space at the front for the entrance and around the sides and back.

If the bouncy castle is going indoors, ceiling height is just as important as floor space. Many halls and community centres have lower ceilings, so smaller inflatables or items from our Mini Low Height Bouncy Castles range are often the safest choice.

Think about the age group

The age of the users affects the size you need. Toddlers and younger children usually need less space and are best suited to smaller bouncy castles or soft play. Equipment from our Soft Play Hire range works well for babies and toddlers and fits easily into indoor venues.

For children aged three and over, standard options from our Bouncy Castles range are suitable for most gardens and halls. Older children often enjoy larger inflatables or bouncy castles with slides from our Bouncy Castles with Slides range, which need more space.

Garden parties

For garden parties, check the width and length of the lawn and make sure there is a clear route for delivery. Smaller gardens usually suit standard bouncy castles, while larger gardens may allow room for wider inflatables or additional features.

It’s also important to check for overhead obstacles such as trees, wires or fences, which can limit where an inflatable can be placed.

Halls, schools and indoor venues

Indoor venues vary widely. Sports halls often allow larger inflatables, while village halls and church halls may have height restrictions. Measuring the ceiling height at its lowest point is essential.

For school events or indoor fun days, many organisers choose a mix of soft play and smaller bouncy castles to suit different age groups and room sizes.

Larger events and open spaces

For school fun days, community events and outdoor festivals, larger spaces allow for bigger inflatables or multiple units. Items such as obstacle courses from our Obstacle Courses range need more room but work well in playgrounds, fields and parks.

If the event is outdoors and power is not available, we can supply a Generator. For longer events, organisers often add a Event Gazebo (10ft x 10ft / 3m x 3m) to help with shelter or queue management.

If you’re unsure

If you’re not certain which size will fit your space, it’s always better to ask before booking. We can advise based on your measurements, venue type and the age of the users.
