Ninja Course Equipment: How to Plan a Kids Ninja Warrior Course

Short answer: Plan a kids ninja warrior course around age bands first, then choose balance, hanging, climbing and wall obstacles that suit them. Give every obstacle its own fall area with tested safety flooring, make heights adjustable, and plan staffing, inspections and classes before you order ninja course equipment.

Ninja courses have moved from television into gyms, trampoline parks and family entertainment centers. They draw kids who don't fit traditional team sports, they support classes and memberships rather than one-off visits, and they photograph well for parties. They are also less standardized than trampoline courts, which puts more of the planning burden on the buyer.

This guide walks through obstacle selection, age bands, space and fall areas, flooring, standards and budget, in the order you should decide them. If you are adding ninja to a trampoline park, read it alongside our guide to trampoline park equipment by zone.

What ninja course equipment does a kids course need?

A kids ninja course needs a mix of obstacle types so children practice balance, grip, climbing and momentum in sequence, plus the frame, padding and flooring that hold it together. The table groups common ninja course equipment by the skill it trains.

Our kids ninja warrior course is built from these modules on a steel frame and drawn to your floor plan; see the full ninja courses and trampoline parks range for related equipment.

Who is the course for? Plan by age band

Age bands set obstacle heights, grip sizes and fall areas, so settle them before you pick obstacles. Ninja gyms serve a wide range: the Star Tribune profiled a Minnesota gym where children as young as 3 take part alongside teens, adults and competitive obstacle racers.

Public playground guidance offers a useful reference for upper-body obstacles. The CPSC Public Playground Safety Handbook says 4-year-olds are generally the youngest children able to use horizontal ladders and overhead rings, and that these should not be used on playgrounds intended for toddlers and 3-year-olds. Its recommendations for these devices are designed for ages 4 through 12.

In practice that suggests three zones:

• Under 4: low balance and crawl elements on soft surfaces, with no overhead hanging obstacles. Our toddler soft play design rules apply here more than ninja rules do.
• About 4 to 7: lower bars, shorter spans, lower climbing walls and a small curved wall.
• About 8 and up: longer hanging sequences, taller walls and momentum obstacles, with adjustable elements for teens and adults.

Adjustability extends the life of the course. In Recreation Management, one industry source described a well-designed course as adjustable enough to suit 12-year-olds, 18-year-olds and professional athletes.

How much space does a ninja course need?

A ninja course needs enough floor for the obstacles, their fall areas and a clear spectator line, and the fall areas often take more space than the obstacles themselves. Dedicated ninja gyms can be large: the Minnesota gym in the Star Tribune profile runs about 10,000 sq ft of obstacles and changes the layout every week. Inside a trampoline park or family entertainment center, a ninja zone can be as compact as a lane along a wall or a loop around a central climbing feature.

Outdoor playground guidance gives reference points for fall areas. The CPSC handbook says the use zone around a standalone climber should extend at least 6 feet in all directions, and that use zones of neighboring equipment may overlap only with at least 6 feet between pieces when adjacent platforms are 30 inches high or less, or 9 feet when they are higher.

Those figures were written for outdoor public playgrounds, not indoor ninja courses, but they are a sensible starting point when you discuss layout with your designer and inspector. Ceiling height is set by the tallest wall, the highest bar plus a child's reach, and any rigging, so measure clear height under beams, ducts and lights before you choose obstacles. Our article on indoor playground layout rules covers circulation and sight lines.

Safety flooring and fall areas

Safety flooring under a ninja course should be chosen from the fall height of the tallest obstacle it serves. The CPSC handbook describes critical height as the fall height below which a life-threatening head injury would not be expected, and says a surface's critical height rating should be at least the fall height of the highest equipment above it. ASTM F1292 is the test method that produces that rating, using g-max and Head Injury Criterion measurements. ASTM lists F1292-26 as the current edition.

For indoor courses, that usually means padded mats rather than loose fill. Options include vinyl soft play safety mats under hanging obstacles and EVA interlocking foam mats for circulation areas, plus wall and column padding wherever a swing or fall could reach a hard surface. Ask for the fall height each mat is rated for and the test basis in writing. Our indoor playground flooring comparison covers the trade-offs.

Which safety standards apply to ninja courses?

No ASTM standard is written specifically for ninja courses yet, so buyers have to borrow from related standards and their local rules. In 2020 an industry source told Recreation Management that ninja was an unregulated industry and that most states did not evaluate ninja products. That is changing slowly: ASTM's amusement rides committee has a proposed practice, WK81308 on adventure challenge attractions, described as collections of physical challenges for patrons to overcome. It draws on the soft contained play, playground and trampoline standards and is not intended for attractions where the patron is clipped in or belayed.

Until a dedicated standard exists, cover three bases:

1. Ask your state. If the course sits inside a trampoline park or amusement venue, your state amusement ride program may treat it as part of the permitted attraction.
2. Get an inspection routine in writing. The same article recommends manuals with daily, weekly and monthly checks plus a yearly inspection by a state inspector or the manufacturer.
3. Watch your incident log. In a 2023 Pediatrics study of 18 trampoline parks, parkour, the activity closest to ninja in that data, had a significant injury rate of 0.22 per 1,000 jumper hours, twice the 0.11 overall rate.

Our indoor playground safety checklist includes daily and weekly inspection items you can adapt for obstacles.

What does a ninja course cost, and how does it earn?

Ninja course budgets range from an equipment-led install to a full dedicated facility. In 2020, an industry source quoted by Recreation Management put ninja facility investment from about $40,000 on equipment to $700,000 to $800,000 or more, and the same article reported Ninja Nation's franchise investment at $1 million to $1.4 million.

The revenue model is what makes ninja attractive. Operators in both articles describe a mix of classes, open gym, memberships, birthday parties, camps and competitions. The Minnesota gym in the Star Tribune reported about 500 members, a waitlist of more than 100 and 15 to 20 parties most weekends, with classes and open gym treated as the core business. Plan coaching staff and a class schedule alongside the equipment, because programming is what brings families back.

On timing, our typical figures are a layout drawing and quote in 1 to 2 weeks, production of 20 to 35 working days after approval, and 4 to 6 weeks of ocean freight to a US port. For cost context across a whole venue, see what it costs to open a trampoline park.
