What Size Bouncy Castle Do I Need for My Party?

Choosing the right size bouncy castle is key to a safe, fun, and stress-free party experience. Whether you're hosting a backyard birthday, a school fair, or an indoor event in Auckland, here's what you need to know to pick the perfect inflatable size.

✅ 1. Know Your Available Space

No matter the surface – grass or hard ground – we always recommend that your setup area is at least half a metre wider and longer than the actual bouncy castle dimensions.

This extra clearance:

  • Makes the setup smoother
  • Prevents rubbing against fences, trees or walls
  • Keeps the blower and safety mats in the right position

💡 For indoor setups, it's also important that the ceiling height is at least 0.5m taller than the height of the bouncy castle.

✅ 2. Check the Product Dimensions Carefully

At Rainbow Bouncy Castle, every product page clearly lists:

  • Actual dimensions (length × width × height)
  • Recommended clearance space
  • Whether it's suitable for indoor or outdoor use

This helps you plan ahead, especially if you're unsure about tight driveways, garages, or community halls.

✅ 3. Match Size with Number of Kids

The ideal bouncy castle size also depends on how many children will be attending your party.

  • Most of our castles support up to 10 children under 10 years old at a time
  • Some smaller bouncy castle are perfect for mini parties or toddlers
  • If you're planning a big event, consider our combo or slide castles for better traffic flow

🎉 Tip: We’re happy to recommend the best fit based on your venue and guest count – just ask!

✅ 4. When in Doubt, Ask Us
