Planning to hire a bouncy Castle but not sure if your garden or venue is big enough?
Here's a simple guide to help you choose the right size and avoid any last-minute surprises.
Minimum Space Requirements
Every inflatable needs a bit of extra space around it for safety.
As a general rule:
-allow at least 1ft (30cm) on each side
-extra space at front for safe entry/exit
-space at the back for blower
For example: a 12ft x 12ft bouncy castle will need around 13ft x 15ft of clear space
Garden Setups
Always check for: slopes, trees, overhead space (very important)
Indoor Venues

If you're hiring a hall:
- check ceiling height
- avoid low beams or lights
