Short answer: What size bounce house fits my yard? Take the unit footprint and add 4 feet of buffer on every side plus 3 feet of overhead clearance. A standard 13x13 bounce house needs roughly 21x21 feet of level ground and a 36-inch gate.
I've been backing trailers down driveways in Kenner, Metairie and Uptown since 1992, and the most common problem I hit isn't weather or power. It's a yard four feet too small — kids dressed, cake out, me at the fence explaining the unit won't go in.
Ten minutes with a tape measure prevents it.
What size bounce house fits my yard if I've never measured before?
Measure the largest rectangle of flat, open ground you have, then subtract 8 feet from the length and the width. What's left is the biggest footprint you can take. A 30-by-24-foot backyard leaves about 22 by 16 feet: a standard bounce house or small combo, not a 40-foot obstacle course.
Measure usable ground, not the property line. AC pads, raised beds, the swing set, the crepe myrtle nobody trims — all of it comes out. And measure at the narrowest point; Old Metairie and Uptown yards are rarely true rectangles.
Why do you need 3 to 5 feet of buffer on every side?
Because a bounce house moves, leans in wind, and anchors outward. On grass we drive stakes angled away from the unit, so anchor points sit 18 to 30 inches past the vinyl. Sandbags sit outside the footprint too.
Then the exit. The front step-off where kids land needs 4 to 5 feet of clear, soft ground. Not a fence. Not a patio edge.
Three feet minimum on the back and sides, 5 at the entrance.
What are typical bounce house dimensions by category?
Footprints vary, so confirm the unit you book.
| Category | Typical footprint | Height | Clear space needed | Min. gate width |
|---|---|---|---|---|
| Toddler / kiddie bouncer | 10 x 10 ft | 8–10 ft | 18 x 18 ft | 36 in |
| Standard bounce house | 13 x 13 ft | 14–15 ft | 21 x 21 ft | 36 in |
| Wet/dry combo | 18 x 20 ft | 16–18 ft | 26 x 28 ft | 42 in |
| Deluxe themed combo | 20 x 25 ft | 18–20 ft | 28 x 33 ft | 48 in |
| Water slide | 15 x 30 ft | 18–22 ft | 23 x 38 ft | 42 in |
| Obstacle course | 12 x 40 ft+ | 12–16 ft | 20 x 48 ft | 42 in |
A kiddie bouncer solves a tight Mid-City or Algiers Point yard more often than people expect. Big flat lots in River Ridge and Destrehan are where deluxe themed combos and water slides pay off.
Will it fit through my gate?
Measure the opening itself, latch post to latch post, gate swung wide. Not the fence panel.
36 inches is my hard floor for a standard unit, 42 inches for combos and slides. Under 36 and we're either pulling the gate off its hinges — happy to, with notice — or we're not getting in.
People forget height and turns. A low arbor stops a unit standing 40 inches tall on the dolly, and an Uptown shotgun house often has a 40-inch gate feeding a 32-inch side walkway with a 90-degree bend.
What overhead obstacles should I look for?
Stand at the center of your spot and look up. You need 3 feet of clear air above the unit's inflated height. The four I hit constantly:
- Power and service lines. We do not set up under a drop line, period.
- Live oak and pecan branches. They look high until a 15-foot unit inflates into them.
- Carport and patio roofs. Usually 8 to 9 feet — toddler units only.
- Balconies and galleries. Common Uptown. Measure to the underside.
What if my yard genuinely won't fit anything?
Then we go to concrete. Roughly a third of my Orleans Parish setups are driveway jobs, anchored with sandbag ballast instead of stakes. Disclose the surface at booking — a crew expecting grass and finding asphalt is a problem.
Three other options:
- Front lawn. Often flatter and wider than the backyard in Gretna and Harahan. Watch for sprinkler heads and the meter box.
- A neighbor's yard. People say yes more than you'd think for a birthday.
- A park or church lot. Park and commercial deliveries carry a $500 minimum versus $150 residential. Check permits with the parish first.
What 5 things should I measure before I call?
- Length and width of the flat, clear rectangle, at its narrowest points.
- Overhead clearance — lowest branch, wire, or roofline above that spot.
- Gate opening, width and height, swung fully open.
- Surface — grass, concrete, asphalt, or a mix.
- Distance to the nearest outlet on a dedicated 20-amp breaker.
Frequently asked questions
How much space does a standard bounce house need? A 13x13 ft bounce house needs about 21x21 ft of clear, level ground and 18 ft of overhead clearance. That's the footprint plus 4 ft of buffer on every side for stakes or sandbag ballast, plus a safe step-off zone at the entrance.
Can you set up a bounce house on concrete or a driveway? Yes. Concrete and asphalt setups use sandbag ballast instead of ground stakes. Tell us the surface when you book so the crew loads the right anchoring. Driveways are the most common fix for tight Uptown, Mid-City, and Algiers Point lots.
What's the minimum gate width for a bounce house? 36 inches for a standard bounce house or toddler unit, 42 to 48 inches for combos, water slides, and obstacle courses. Measure the actual opening with the gate swung wide, then check for low arbors and tight turns along the path.
Does the yard need to be level? A slight grade is workable. A noticeable slope shifts the unit under load and pools water on wet slides. If your yard drops more than a few inches across the footprint, the driveway or the front lawn is usually the better spot.
What if my yard is too small for the unit I want? We'll size you down to something that fits, or set up on the driveway with sandbag ballast. Smaller bounce houses run all afternoon just as well as the big ones. Send us your measurements and we'll match inventory to your space.
