Trampoline Park Injury Rates by Zone: What 2024 Data Shows
High-performance areas at trampoline parks recorded 2.11 injuries per 1,000 jumper hours. Airbag and foam pit areas recorded 1.91. The park-wide average was 1.14.
Those three figures come from the largest exposure-based study of trampoline park safety published so far. A team led by Warwick Teague at The Royal Children’s Hospital in Melbourne, reporting in Pediatrics in January 2024, analyzed injury records and ticket-sales data from 18 parks in Australia and the Middle East between 2017 and 2019. The dataset covered 8.39 million jumper hours and 13,256 reported injuries.
Most safety conversations in this industry run on anecdotes: one viral video, one lawsuit headline, one operator’s war story. This study does something rarer. It attaches a denominator, and a denominator is what turns a story into a rate you can benchmark against.
If you are budgeting for a trampoline park, these trampoline park injury rates touch three lines in your plan: insurance, staffing and maintenance. This article walks through the raw data, converts it into sessions and park-years, states clearly what the numbers cannot tell you, and closes with decision rules you can apply to your own floor plan.
One caution before the tables. Injury rates describe where injuries were reported, not what caused them. A link between a zone and an injury count is not proof that the zone design is at fault. The boundaries come up again where they matter.
1. Where Injuries Cluster: The Zone-Level Numbers
The study’s unit of exposure is the jumper hour: one person jumping for one hour. Exposure was derived from ticket sales, so the denominator reflects real usage rather than an estimate. Table 1 reproduces the published rates without adjustment.
| Measure | Rate per 1,000 jumper hours | 95% confidence interval |
|---|---|---|
| All injuries, park average | 1.14 | 1.00 to 1.28 |
| High-performance areas | 2.11 | 1.66 to 2.56 |
| Airbag and foam pit areas | 1.91 | 1.35 to 2.50 |
| Significant injuries, park average | 0.11 | 0.10 to 0.13 |
| Significant injuries, high-performance areas | 0.29 | 0.23 to 0.36 |
| Significant injuries, parkour areas | 0.22 | 0.15 to 0.28 |
“Significant” is the study’s term for injuries beyond minor first aid. Eleven percent of the 13,256 reported injuries, roughly 1,458 cases, fell into that category.
Two notes on reading the table. First, simple division of the headline counts, 13,256 injuries across 8,387,178 jumper hours, gives 1.58 per 1,000 jumper hours. The published 1.14 comes from a statistical model that adjusts for park-level variation and reporting structure. We quote both because the gap shows how much method matters; the modeled figure is the more defensible one.
Second, the confidence interval for the airbag and foam pit rate (1.35 to 2.50) overlaps the park average (1.00 to 1.28). The zone gap is a strong planning signal, not a statistically airtight result. Treat it accordingly.
Where these numbers come from: Teague WJ, Dipnall JF, Palmer CS and Beck B, “Trampoline Park Injury Trends”, Pediatrics, January 2024. The parks studied operated in compliance with recognized safety standards, and the authors used industry ticket data to build the exposure denominator.
2. From Jumper Hours to Sessions and Years: The Conversions
Nobody books a park in jumper hours, so the rates need converting. The arithmetic is one line:
Expected injuries per year = (annual jumper hours ÷ 1,000) × rate per 1,000 jumper hours
A one-hour jump session equals one jumper hour. At the modeled park average of 1.14, one reported injury occurred for roughly every 877 one-hour sessions; on the raw count of 1.58, one for every 633. Table 2 summarizes the conversions used in the rest of this article.
| Benchmark | Raw count basis (1.58 per 1,000) | Modeled basis (1.14 per 1,000) |
|---|---|---|
| One reported injury per X one-hour sessions | about 633 | about 877 |
| Reported injuries per 100,000 jumper hours | about 158 | about 114 |
| Significant injuries per 100,000 jumper hours | about 17 | about 11 |
| Park example below: reported injuries per year | about 173 | about 125 |
Here is the worked example behind the last row. Take a mid-size park open 12 hours a day with an average of 25 jumpers on the floor. That is 300 jumper hours per day, or about 109,500 per year. Multiply 109.5 by 1.14 and you get roughly 125 reported injuries a year; multiply by 1.58 and you get 173. Apply the significant-injury rate of 0.11 to 0.17 per 1,000 jumper hours and the same park should expect somewhere between 12 and 19 significant injuries a year. These are derived calculations from the published rates, not figures released by any operator.
Before alarm sets in: a “reported injury” in this study includes minor first-aid events, such as bruises and small sprains handled at the front desk. A park handling hundreds of thousands of visits a year will log that kind of event routinely. The useful read is the benchmark, not the scare.
3. What the Data Does and Does Not Show
This section is the boundary of the analysis, and it matters more than the tables.
The sample has a geography The 18 parks operated in Australia and the Middle East between 2017 and 2019. No United States, European or Chinese parks are in the dataset. Rates from compliant parks in one region do not transfer automatically to another regulatory environment, but the method, and the zone pattern, travel better than the absolute numbers.
The parks were compliant The study describes the parks as operating in compliance with recognized safety standards. These rates therefore describe what “good” looked like in practice, not what happens in unregulated venues. An operator using the benchmark should also be operating to standard; our overview of global safety certifications for indoor trampoline parks covers which certificates apply where.
Injuries are operator-reported The counts come from park incident records. Minor events may be logged in one venue and waved off in another, and reporting culture shifts the numerator even when the real rate is unchanged. That is one reason the raw and modeled figures differ.
Zone boundaries are operator-defined The study attributed injuries to zones using each park’s internal records. Where one operator’s “foam pit area” ends and the dodgeball court begins is not standardized across the industry.
Association, not causation A zone with a high injury rate may simply be the zone most people use, or the zone where beginners attempt the hardest tricks. Nothing in this study proves that a given attraction causes injury, and any supplier or consultant who reads cause into these rates is selling you something.
The denominator is the point Registry studies count emergency-department visits without knowing how many people jumped. This study’s jumper-hour denominator is what makes its rates comparable across parks and across time. Never compare 1.14 injuries per 1,000 jumper hours with an emergency-visit percentage; they measure different things.
4. High-Performance Areas and Parkour: Where Significant Injuries Concentrate
The overall significant-injury rate is 0.11 per 1,000 jumper hours. In high-performance areas it is 0.29, about 2.6 times the park average. In parkour areas it is 0.22, about double. The overall injury rate in high-performance areas, 2.11, sits roughly 85 percent above the park-wide average.
The pattern is consistent: when a park dedicates floor area to advanced jumping, the injuries that do occur are more likely to be the kind that end up in hospital. High-performance areas attract skilled users working near the limit of their ability, which is exactly where margin for error is thinnest.
Three operational responses follow directly from the numbers.
Staff coverage These zones justify dedicated spotters or instructors rather than shared floor staff. Supervision density is the variable an operator controls most directly.
Access control Skill or age gating before entry costs less than the incident it prevents. The registries in Section 6 repeatedly associate park injuries with adolescents, the group most drawn to advanced zones.
Scheduling Concentrating advanced sessions into supervised blocks reduces mixed-skill collisions. Open access for all ages on the same court pairs the lightest users with the heaviest.
None of this is free. A dedicated instructor on every advanced session is a real wage line. But one significant spinal or open-fracture case carries costs beyond medical bills: the zone closes during investigation, claims consume management time, and local coverage of a serious injury follows a venue for years. The wage line is the cheaper line.
5. Foam Pits and Airbags: High Frequency, Mostly Manageable
Airbag and foam pit areas recorded 1.91 injuries per 1,000 jumper hours. Divide that by the park average of 1.14 and you get 1.68: these landing zones ran roughly two-thirds above the average injury rate, the highest frequency of any standard zone.
The explanation is probably mundane. Nearly every jump in a park ends in a landing zone, so those surfaces concentrate usage, and concentrated usage produces events. High frequency does not automatically mean high severity; the significant-injury concentration sits with the advanced zones, not with the landing zones.
The injury profile supports that. Kasmire and colleagues, analyzing United States emergency-department data in Pediatrics in 2016, found that trampoline park injuries were more likely than home trampoline injuries to involve the lower extremity (odds ratio 2.39). The Korean nationwide registry discussed below found the lower extremity accounted for 47 percent of pediatric trampoline injuries. These are landing-related patterns, and landing zones are where landings happen.
Operationally, this zone rewards boring consistency. Foam blocks compress and degrade, bed tension drifts, padding wears thin at the edges where traffic is heaviest. A fixed inspection cycle for landing surfaces catches degradation before it becomes a case. What the surfacing is made of matters as much as how it is inspected; we cover the materials question on our materials and quality page, and replacement items from foam blocks to bed panels are listed under trampoline park accessories.
On standards: ASTM F2970 covers commercial indoor trampoline courts in the United States framework, while EN ISO 23659 is the corresponding European standard for trampoline parks. Both impose requirements on these landing zones, and both are versioned documents, so check which edition your market enforces rather than copying numbers between jurisdictions.
6. What the Emergency-Department Registries Add
Exposure-based studies like the Melbourne one are rare. Three registry-based analyses fill the picture in from the injury side, each with a different population and a different decade.
United States, 2010 to 2014 Kasmire and colleagues estimated that emergency-department visits for trampoline park injuries rose from 581 in 2010 to 6,932 in 2014. Compared with home trampoline injuries, park injuries were more likely to involve the lower extremity, more likely to be dislocations, and more likely to warrant hospital admission (odds ratio 1.76). The admissions included open fractures and spinal cord injuries.
South Korea, 2011 to 2016 Choi and colleagues used a nationwide emergency-department surveillance database covering 263,712 pediatric injuries, of which 2,799 were trampoline-related. Seventy-six percent happened at trampoline parks. Fractures accounted for 31.7 percent of cases, and park cases fractured more often than home cases (33.7 percent versus 21.1 percent). The lower extremity accounted for 47 percent of injuries, the head and face 24 percent, and the upper extremity 24 percent.
United States, 2008 to 2017 An analysis presented at the American Academy of Pediatrics conference in 2019 found pediatric trampoline fractures rose from 35.3 to 53.0 per 100,000 person-years over the decade, and the share of all pediatric fractures caused by trampolines climbed from 3.59 percent to 6.16 percent. Neck injuries, the outcome investors fear most, stayed rare: an analysis of 33,929 pediatric trampoline injuries between 2012 and 2021 found 4.2 percent involved the neck, and most of those were strains or sprains rather than fractures.
Registry counts rise partly because parks multiplied, so without exposure data you cannot separate a rising rate from a rising user base. That is precisely the gap the jumper-hour denominator closes, and when the Melbourne team closed it, the trend line bent the other way: injury rates in their compliant parks fell by 0.72 percent per month across the study window.
The registry and exposure data agree on one more thing. Fracture patterns cluster in the extremities, hospital admissions skew toward park users, and the significant-injury concentration in the zone study sits with advanced jumping. Different datasets, built by different teams on different continents, point at the same operational conclusion.
7. Turning Rates Into Operating Decisions
Raw rates are a starting point. The value appears when they enter four decisions.
Benchmarking Track reported injuries per 1,000 jumper hours monthly, using your own ticket data. The compliant-park band runs from about 1.1 to 1.6. A park hovering above it has a supervision, layout or maintenance problem worth finding; a park far below it may have a reporting problem instead of a safety record. Act on the trend, not on single events, and expect gradual improvement as staff routines mature, because that is what the study observed.
Insurance Insurers price what they can measure. Bringing an exposure-based incident metric, with a denominator attached, changes that conversation from anecdotes to actuarial terms. Few operators track this number, which is why the ones who do tend to stand out in negotiations.
Layout and program mix Adding a high-performance wall or a parkour block imports that zone’s significant-injury profile along with its marketing appeal. The trade can be worth making, but it should be priced in staffing and supervision at design time. How a floor splits between zones of different risk is exactly the question our breakdown of a 22,000 sq ft (2,044 m²) trampoline park layout walks through, and the trampoline park equipment range shows what each zone option looks like in practice.
Procurement When comparing suppliers, ask two questions the injury literature makes relevant: how zones are delineated in the design, and what inspection cycle the landing surfaces need to stay within specification. A supplier who answers both without hesitation has thought about operations, not just delivery. Our getting-started process builds both questions into the design and quotation stage.
8. Summary: Decision Rules, Not Predictions
The data supports a short list of rules rather than a forecast. Applied in order, they cover most situations an investor or operator will meet.
1. If your program includes high-performance walls or parkour, budget dedicated supervision and access control at design time, because those zones run about 2.6 times the park average for significant injuries.
2. If you operate a standard court-and-landing-zone park, track reported injuries per 1,000 jumper hours monthly and compare against the 1.1 to 1.6 compliant-park band, acting on trends rather than single events.
3. If a risk number arrives without a denominator, do not build a decision on it. Injury counts without exposure, and percentages without a stated base, describe nothing actionable.
4. If you are choosing between suppliers or designs, ask how the floor plan handles the two zones where the data concentrates: advanced jumping and landing surfaces. The answers reveal operational maturity faster than any catalog.
5. If your floor plan is still open, you are at the cheapest point to absorb all of the above. Once steel is cut, every supervision and access requirement becomes a retrofit.
FAQ
What is the injury rate at a trampoline park per jumper hour?
The best exposure-based study to date reports 1.14 injuries per 1,000 jumper hours as the modeled park average, with 1.58 per 1,000 on a simple raw count. About 11 percent of reported injuries were classified as significant, at 0.11 per 1,000 jumper hours.
Which areas of a trampoline park have the most injuries?
High-performance areas recorded 2.11 injuries per 1,000 jumper hours and airbag or foam pit areas 1.91, against a park average of 1.14. For significant injuries, the concentration shifts to high-performance areas (0.29 per 1,000) and parkour (0.22), both well above the overall 0.11.
How many injuries should a trampoline park expect per year?
Multiply annual jumper hours by the rate: a park open 12 hours a day averaging 25 jumpers logs about 109,500 jumper hours a year, which converts to roughly 125 to 173 reported injuries and 12 to 19 significant ones. These are derived figures from published rates, not operator disclosures, and “reported” includes minor first-aid events.
Are trampoline park injuries mostly fractures?
No, though fractures are the largest serious share. In the Korean nationwide registry, 31.7 percent of pediatric trampoline emergency visits involved fractures, behind sprains and contusions at 43 percent. Park injuries fractured more often than home injuries (33.7 percent versus 21.1 percent) and the lower extremity was the most affected region at 47 percent.
Do safety standards actually reduce trampoline park injuries?
The 2024 Pediatrics study covered parks operating in compliance with recognized safety standards and found injury rates declining by 0.72 percent per month across the study window. That association cannot isolate the effect of the standards themselves, but it shows compliant parks trending safer over time. See our pages on safety standards and global certifications for which frameworks apply in your market.
