School Gym Inflatable Rentals Walpole MA: Winter Carnival Sizing Guide

Answer: To size school gym inflatable rentals in Walpole, measure the open floor, the lowest ceiling point, and the narrowest door first. Then pick units from the sizes on our live product pages: one bounce house or toddler playground for a half court, an obstacle course plus two or three games for a full gym. Book a December through February event 60 to 90 days out. AJT Bounce delivers from Foxborough, sets up, and can provide additional insured certificates naming your school or hall.

Winter is gym season for Walpole parent groups. Walpole Public Schools parent groups are called PACs (Parent Advisory Councils), and a PAC family night, church fair, or scout party in January shares one rule: everything has to fit indoors. This guide works backward from your floor plan.

Step 1: Know which Walpole room you are booking

Who you call depends on the building.

Public school gyms and cafeterias. The Walpole Recreation Department says school rentals, including gyms, are handled by the School Department. Requests go through the Facility Request Form on the Walpole Public Schools website (135 School Street, 508-660-7200). District buildings include Boyden, Elm Street, Fisher, Old Post Road, Walpole Middle School, and Walpole High.
Blackburn Hall, 30 Stone Street. The Recreation Department rents the Main Hall, Lower Blackburn Hall, or the entire building. Its rental FAQ says outside vendors must be licensed and insured, and staff may ask for a copy of the vendor's insurance. Name your vendors when you book.
Parish schools and church halls. Blessed Sacrament School at 808 East Street is one example of a private campus that hosts its own winter events. Ask the parish office directly about inflatables, load-in time, and insurance.

Whichever room you land, get the inflatable approval in writing, and ask us for a certificate of insurance listing the school, town, or parish as additional insured.

Step 2: Match the floor to the units

A regulation high school basketball court is 84 ft by 50 ft (NFHS), and many elementary gyms are smaller, so measure your own. Leave walkways around every unit and keep exits clear. Sizes below are listed length x width, then height, straight from each unit's page on ajtbounce.com.

Space	Typical crowd	Units that fit
Cafeteria, library corner, or stage apron	Classroom party or small family night	Zap-A-Mole 10 x 5 ft, 6 ft high; Grab Luck Deluxe Claw Machine 3 x 3 ft; Claw Machine 1.5 x 2 ft; Drums Battle 4.5 x 10 ft
Half court or small elementary gym	Younger grades, one station at a time	Basic Bounce House 13 x 13 ft, 13 ft high; Glacier Castle Bounce 14 x 14 ft, 14 ft high; Toddler Tiny Shark Playground 20 x 22.5 ft, 10.5 ft high; Inflatable Tunnel 16.5 x 10 ft, 11 ft high
Full elementary or middle school gym	Whole-school carnival with rotating grades	30' Elite Challenge Obstacle Course 30 x 10 ft, 10 ft high; Wacky Obstacle Course 30 x 10 ft, 9 ft high; Double Dunk Basketball Game 10 x 14 ft, 15 ft high; Ultimate Dual Axe Throw 15 x 15 ft, 8 ft high
High school gym or field house	Middle and high school crowds, town-wide nights	Laser Tag Arena 20 x 25 ft, 11 ft high; Boxing Ring 25 x 25 ft, 10 ft high; 40' Ultimate Challenge Obstacle Course 40 x 11 ft, 12 ft high; Xtreme Dance Dome 17 x 35 ft, 20 ft high

December theme? The Christmas Gnome Ring Toss (9 x 8 ft, 6 ft high) fits a cafeteria.

Step 3: Check ceilings, doors, and the load-in path

Gym ceilings are usually generous, but basketball hoops, divider curtains, scoreboards, and hanging banners are not. Measure under the lowest obstruction above where the unit will sit, and add a few feet of headroom over the listed height.

Next, walk the route our crew will use. Note the double doors closest to the gym, any steps or a stage lift, and how far the parking spot is from the floor. Rolled-up inflatables are heavy, so a short, direct path with a ramp saves real time on event day.

Step 4: Plan power and floor protection

Each inflatable runs on a blower that stays on the whole event. Ask the custodian which wall outlets sit on separate circuits, and send us a sketch with outlet locations marked. If the outlets are on the wrong side of the room, tell us early. Generators belong outdoors, so indoor setups should plan around building power.

Gym floors are a big investment for a school. Ask the facility what floor covering it requires under units, game stations, and food tables, and share that rule with us when you book. Keep concessions like a popcorn or cotton candy machine on the cafeteria side, away from the hardwood.

Step 5: Do the throughput math

Lines are what make or break a gym night. A simple way to estimate:

Pick a turn length (two to three minutes works for most bounce and game stations).
Ask our crew for the rider limit on each unit at setup.
Turns per hour = (60 / turn length) x riders per turn.

For example, a three-minute turn with four riders gives about 80 turns an hour on one unit. If 200 kids arrive over two hours and each wants three turns, plan on several stations, not one. Obstacle courses move faster because two kids race side by side and finish quickly. Low-capacity games like the claw machine work best as a bonus, not the main draw.

Step 6: Staff it like a carnival

Every inflatable needs one adult watching it the whole time it is in use. A two-hour roster that works for most PAC nights:

One monitor per inflatable, swapped every 45 minutes.
One line manager per two stations to count turns and hold the next group.
A shoe-check table near each unit, with bins labeled by grade.
One floater with the custodian's cell number and the outlet sketch.

Separate little kids and big kids by time block, not just by unit. A K-2 hour followed by a grades 3-5 hour keeps the bounce house calmer.

Step 7: Book December through February dates early

Dates around school breaks go first. Third-party copies of the 2026-2027 Walpole Public Schools calendar list winter recess December 23 to January 1, Martin Luther King Jr. Day on January 18, and February recess February 15 to 19.

Count back 60 to 90 days from your event. A mid-January family night means booking in late October or November, about when your facility request should go in. Confirm the official district calendar before you print flyers.

FAQ: Walpole school and hall inflatable rentals

Who approves an inflatable in a Walpole public school gym?

The School Department. The Recreation Department refers gym and school rentals there, and requests start with the district's Facility Request Form.

Can our PAC rent Blackburn Hall and bring in an outside inflatable company?

The hall's FAQ says outside vendors are allowed if they are licensed and insured, and staff may want a copy of the insurance. Tell them it is AJT Bounce when you book, and we can send the certificate.

What is the best single unit for a half-court gym?

For younger grades, a 13 x 13 ft bounce house or the Toddler Tiny Shark Playground. For mixed ages, the 30 ft obstacle courses keep the line moving.

How many adult volunteers do we need per inflatable?

Plan on at least one dedicated monitor per unit at all times, plus a line helper for every two stations and relief shifts.

Do you need to arrive before the event starts?

Yes. Ask the facility for an early load-in window and a matching pickup window, and give us both times so we can schedule the crew.

Can you set up in a church hall with a low ceiling?

Often, with the right unit. Games like Zap-A-Mole (6 ft high) and the Ultimate Dual Axe Throw (8 ft high) fit lower rooms. Send us the ceiling height and we will match units to it.
