What Size Bounce House Do I Need? (Sizing Guide)

Picking the right size bounce house comes down to three things: your yard, your guest list, and the kids' ages. Here's how to get it right for your Port St. Lucie party.

Measure your space first

Before you book, measure the area where the inflatable will go — and remember you need clearance on all sides plus room for the blower and stakes. Here's a rough guide:

Standard bounce houses (~13' x 13'): fit most suburban backyards; great for up to 6–8 smaller kids at a time
Combo units (~18' x 20' and up): need a bigger yard; combine bouncing, climbing, and sliding
Water slides (our 22ft slides): need the most space — a long, clear run plus splash zone and overhead clearance

Not sure? Send us a photo of your yard to 772-801-7126 and we'll confirm the fit before you book.

Match the unit to the kids

Ages 2–5: smaller bounce houses like our Pink Castle Combo — lower walls, gentle bouncing
Ages 5–12: combos like the Rainbow Combo or Retro Combo — more features, more room
Teens and adults: our 22ft water slides are built for bigger riders — ask us which units fit your group

The golden rule: bigger than you think

Almost every parent tells us the same thing after the party: "I wish I'd gotten the bigger one." Kids pile in together, and a unit that's slightly roomy beats one that's packed wall-to-wall. When in doubt, size up — especially for backyard parties with 15+ kids.

Don't forget the extras

A bigger unit doesn't help if there's nowhere to sit. Add tables and chairs for food and rest areas, and consider a tent for shade — Florida sun is relentless.

Frequently asked questions

Will a bounce house fit in my yard?
Most likely, yes. Standard units fit typical Port St. Lucie backyards. Measure your space or send us a photo and we'll confirm.

How many kids can use it at once?
It depends on the unit and the kids' sizes — we'll give you the safe capacity for whichever unit you choose.

What surface do you need?
Grass is ideal. We can set up on concrete with sandbags — just tell us when booking.
