The Complete Guide to Bounce House Sizing
Choosing the right bounce house size is one of the most important decisions when planning your event. Too small and kids are cramped; too large and it won’t fit your space. After delivering over 5,000 bounce houses across Tampa Bay, here’s our expert guide to picking the perfect size.
Understanding Bounce House Dimensions
Bounce house sizes are measured in Length x Width x Height (in feet). Here’s what each size category means for your event:
Standard Bounce Houses (13×13 ft)
Our most popular size for backyard birthday parties. These fit comfortably in most Tampa backyards and accommodate 6-8 kids at a time. Perfect for ages 3-12. Examples include our Melting Arctic, Frozen, and Castle bounce houses — all priced at just $172/day.
Space needed: At least 16×16 ft of flat ground plus 3 ft clearance on all sides. That’s roughly a 20×20 ft area.
Combo Units (18×13 ft)
These combine a bounce area with a slide, climbing wall, and often a basketball hoop. They’re larger but deliver more activities in one unit. Accommodates 8-10 kids. Our combo units are $275/day — an incredible value for the amount of entertainment they provide.
Space needed: At least 22×17 ft of flat ground.
Water Slides (18×10 ft)
Our water slides range from 14-18 ft tall and are the stars of summer parties. They require a flat area plus access to a water source (garden hose). One rider at a time for safety. Priced from $255-$319/day.
Space needed: At least 22×14 ft plus room for the splash zone.
Obstacle Courses (40-45 ft long)
These are our largest units and are perfect for school carnivals, church festivals, and corporate events. The 40-foot Island Drop accommodates 2 racers at a time, while the 45-foot Radical Rampage is our premium option.
Space needed: At least 50×16 ft — typically too large for standard backyards.

Measuring Your Space
Before booking, measure your setup area and keep these tips in mind:
- Allow at least 3 feet of clearance on all sides of the inflatable
- Check for overhead obstacles (trees, power lines, awnings)
- Ensure there’s a standard electrical outlet within 50 feet
- Grass is preferred, but concrete works too (we provide ground tarps)
- The area must be reasonably flat — slopes can be dangerous
