How much space do I need for a bounce house?
The short version: we need a minimum of 2 ft of clearance on all sides, and every unit publishes its own space required figure. Across our bounce house range that lands between 16 ft x 16 ft and 20 ft x 20 ft.
There are two numbers on every product page we publish, and they are not the same number. One is the size of the bounce house. The other is the size of the space we need to set it up.
Measuring the first one and booking against it is an easy mistake to make. So here is the rule we publish, the real figures from our current catalog, and the things worth checking before you book.
The rule, as we publish it
"We need a minimum of 2 ft of clearance on all sides of the inflatable. A 17 ft x 17 ft area is required for 13 ft x 13 ft bounce houses, 17 ft x 22 ft for most combo units, and 32 ft x 15 ft for most slides. The area should be flat, free of debris, rocks, and trees."
KidZone Party Rentals FAQThose are the general guides. Each unit also lists its own Space Required figure on its product page, and that per-unit number is the one to measure against, because it already includes the clearance. For combos and slides in particular, a good number of units need more than the general guide suggests.
Actual size is not space required
Every product page shows two dimensions, and confusing them is the single most common mistake we see.
- Actual Size is the inflatable itself, sitting there fully inflated.
- Space Required is the cleared area we need to set it up safely, clearance included.
Take our All Sports Bouncer. Actual size 15 x 15. Space required 20 x 20. A 16 ft gap between the deck and the fence sounds like enough room for a 15 ft unit, and it is not, because 20 x 20 is the figure we publish for that unit.
The gap between the two numbers is the clearance our FAQ describes, which is a minimum of 2 ft on all sides. Measure against the larger number and the question does not come up.
What our bounce houses actually need
These are the published figures for every bounce house in our range, grouped by the space they need. All of them are current as of August 2026.
16 ft x 16 ft
- Crystal Bounce House, unit is 15 x 15
- Halloween Bounce House, unit is 13 x 13
18 ft x 18 ft
- All American Bounce House, unit is 14 ft long x 12.5 ft wide x 15.5 ft high
- Castle 2 Jump, unit is 15 x 15
- Jurassic Bounce House, unit is 15 x 15
- Wacky Castle, unit is 15 x 15
20 ft x 20 ft
- All Sports Bouncer, Dream Castle, Extreme Castle, Football Player, Fun House, Jack The Bouncer, KidZone Castle, Nuclear Inferno Bouncer, Unicorn Bounce House and Wacky Bouncer, all 15 x 15 units
- Ferris Wheel Bounce House, unit is 15 ft long x 15 ft wide x 13.3 ft high
- Monster Truck, unit is 15 x 18
- Fairy Garden, unit is 16 x 16
Two units in the range, the Space Bouncer and the Justice League, do not currently publish a space required figure. Rather than guess at one here, call us with your measurements before booking either of those.
The practical takeaway: if you can clear a flat 20 ft x 20 ft square, every bounce house we rent will fit it. If you cannot, you are looking at the 16 ft and 18 ft group, and it is worth measuring before you fall in love with a theme.
Slides and obstacle courses are a different conversation
People tend to assume a water slide needs a bit more room than a bounce house. It needs a lot more, and it is length that changes rather than width. Here is the honest span across our catalog.
- Bounce houses: 16 x 16 up to 20 x 20.
- Bounce and slide combos: typically 18 x 25 up to 20 x 30, with the largest in the range needing 40 x 30.
- Water slides: from 18 x 25 up to 30 x 50, with our 24 ft Raging River needing 50 x 20.
- Obstacle courses: from around 15 x 40, up to 20 x 125 for our 105 ft course.
That last figure is not a typo. A 105 ft course needs more length than most residential lots have in any one direction, so it is worth measuring before you set your heart on one.
Three more things to check
1. Look up
It is easy to measure the ground and forget the air above it. Height is published less consistently than footprint across our catalog: most bounce house listings give a footprint only, and the two that do publish a height are the All American Bounce House at 15.5 ft and the Ferris Wheel Bounce House at 13.3 ft. At the other end of the range, our tallest water slide is the 24 ft Raging River.
Overhanging branches, power lines, roof eaves, gutters and basketball hoops all sit in that band. The published requirement that the area be free of trees is worth reading as being about the canopy above the spot as much as the trunk beside it. If the listing for your unit does not show a height and clearance overhead looks tight, ask us before you book.
2. Power
Every unit lists a 110V outlet requirement on its product page, so you need a working outlet in reach of the setup spot. Larger units, particularly the long obstacle courses, list more than one. Check the figure on the specific unit rather than assuming one outlet covers it.
Our own advice on this is blunt, and it is on our FAQ page: "make sure your outside plug is working." Test it the week before, not on the morning.
If there is no outlet in reach, that is a solved problem rather than a dealbreaker. Our FAQ states it directly: "If a 110V outlet is not available, such as at a park, we can provide a power generator for an additional charge." Worth flagging when you book, because it changes the total.
3. Surface, stakes and what is under the grass
We can set up on grass, pavement, or indoors, and the area should be flat and free of debris and rocks. The part worth reading twice is what holds the unit down.
"Our units are staked into the ground for stability and safety. Therefore, the renter is responsible for having all utilities located prior to their party."
KidZone Party Rentals FAQStakes go into the ground, so anything buried in that ground is worth locating first: irrigation lines, invisible dog fence wire, low voltage lighting cable, gas and utility runs. Indiana 811 is the state's free call-before-you-dig service and is the usual way to get buried utilities marked. On the same theme, our FAQ asks that if you have an in-ground sprinkler system, you make sure the timer is not set to go on.
How to measure your yard in five minutes
Our first piece of advice to every customer is one word: "Measure." Here is the whole job.
- Pick the spot first. Flat, open, away from the fence line, ideally within sight of the house.
- Measure both directions and write down the smaller number. That is your real limit.
- Stand in the middle and look straight up. If you can see branches or wires, move the spot.
- Find the nearest outdoor outlet and check it works.
- Compare your number to Space Required on the unit's product page, not to Actual Size.
If your measurement lands within a foot or two of the published requirement, call us with the numbers before you book rather than after.
Where to check the figure for your unit
Every unit publishes its own actual size, space required and outlet requirement on its product page. You can browse the full range on our bounce house rentals page, and the general space rule, the surface requirements and the utility locating policy are all on our FAQ page. If anything here ever disagrees with those pages, the product page and the FAQ are the authority.
Common questions
How much space do I need for a bounce house?
We need a minimum of 2 ft of clearance on all sides of the inflatable. As a general guide we publish, a 17 ft x 17 ft area is required for 13 ft x 13 ft bounce houses, 17 ft x 22 ft for most combo units, and 32 ft x 15 ft for most slides. Every unit also lists its own space required figure on its product page, and that per-unit number is the one to measure against. Across our current bounce house range those figures run from 16 ft x 16 ft to 20 ft x 20 ft.
Is the space required the same as the size of the bounce house?
No, and this is the most common booking mistake. Actual size is the inflatable itself. Space required is the cleared area we need to set it up safely, including a minimum of 2 ft of clearance on all sides. A 15 ft x 15 ft bounce house does not fit in a 15 ft x 15 ft gap. Measure against the space required figure on the product page, never the actual size.
What surface can a bounce house be set up on?
We can set up on grass, pavement, or indoors. The area should be flat, free of debris, rocks, and trees. Our units are staked into the ground for stability and safety, so the renter is responsible for having all utilities located prior to their party. If you have an in-ground sprinkler system, please make sure the timer is not set to go on.
Do I need an electrical outlet for a bounce house?
Yes. Every unit lists a 110V outlet requirement on its product page, so you need a working outlet in reach of the setup spot. Larger units, particularly long obstacle courses, list more than one. Our own advice before your event is to make sure your outside plug is working. If a 110V outlet is not available, such as at a park, we can provide a power generator for an additional charge.
How much overhead clearance does a bounce house need?
It depends on the unit, and height is published less consistently than footprint in our catalog. Most bounce house listings give a footprint only. The two that do publish a height are the All American Bounce House at 15.5 ft and the Ferris Wheel Bounce House at 13.3 ft, and our tallest water slide is the 24 ft Raging River. The published requirement is that the area is free of debris, rocks, and trees, so check for overhanging branches, power lines, roof eaves and basketball hoops above your chosen spot, not just the footprint on the grass. If the listing for your unit does not show a height, ask us before you book.
How much more space does a water slide or obstacle course need?
Considerably more, and length is what changes rather than width. Bounce houses in our range need 16 ft x 16 ft up to 20 ft x 20 ft. Combo units with a slide typically need 18 ft x 25 ft up to 20 ft x 30 ft. Water slides run from 18 ft x 25 ft to 30 ft x 50 ft. Obstacle courses start around 15 ft x 40 ft and the longest in our range needs 20 ft x 125 ft. Check the space required figure on the specific unit before you book.
Every space, surface and power figure on this page was taken from our own product pages and FAQ as published on August 13, 2026. Our catalog changes, so the product page for your unit is always the current authority.
Not sure it fits?
Every unit's space required figure is published on its own product page. If yours is close to the limit, call with your measurements and the unit you have in mind before you book.
