When planning a party or event, one question always pops up: What size bouncy castle should I rent? Picking the right size isn’t just about making sure it fits in your space – it’s about ensuring everyone has fun, stays safe, and gets the best value for your rental.
In this guide, we’ll walk you through how to choose the perfect size bouncy castle so your celebration goes off without a hitch.
1. Consider Your Guest List – Especially the Age Group
The size of your bouncy castle depends heavily on who’s using it.
- Toddlers (2–5 years old): Go for smaller castles (2.4m x 2.4m to 3m x 3m). These are safer for young children and require less supervision.
- Primary School Kids (6–12 years old): Medium-sized castles (3.6m x 3.6m to 4m x 4m) work best. They have enough bounce for active kids while keeping it safe.
- Mixed Ages or Adults: Choose large castles (5m x 5m and above) or inflatable obstacle courses to accommodate different sizes and energy levels.
Pro Tip: Never overload a bouncy castle – we will give you the maximum capacity to follow.
2. Measure Your Event Space Before Booking
It sounds obvious, but you’d be surprised how many people book first and measure later!
- Outdoor events: Check the grass or open space area. Allow at least 1 metre clearance around the castle for safety mats and anchoring.
- Indoor events: Measure both the floor space and the ceiling height – some castles need more than 3 metres in height clearance.
A good rental company (like us!) can recommend models that fit your space perfectly.
3. Match the Castle to Your Theme
Size isn’t just about dimensions – it’s about presence. A large, colourful castle can become the centrepiece of your event, while a smaller themed inflatable can be tucked into a play area.
Popular themes by size:
- Small: Animal or cartoon designs for toddlers
- Medium: Unicorn, dinosaur, or superhero designs
- Large: Obstacle courses, slides, or multi-activity inflatables
4. Think About Safety and Supervision
Bigger isn’t always better if you don’t have the manpower to supervise.
- For small to medium castles, one adult supervisor is usually enough.
- For large inflatables or mixed-age groups, you may need two or more.
Choose a size that matches your ability to keep everyone safe while having fun.
5. Factor in Your Budget
While larger castles cost more to rent, they also accommodate more people and can reduce waiting times. If you have a small guest list, a medium-sized bouncy castle might be the perfect balance between cost and enjoyment.
