Choosing the right trampoline size has large implications on safety, fun, and long-term usability. Akrobat has spent years innovating trampoline design and performance. We can tell you that size matters more than most people realize. And it’s not as simple as, “well, can it fit all of my kids?”
A poorly chosen trampoline can lead to unnecessary injuries, wasted money, and frustration. Whether you’re buying for kids, adults, families, or serious athletes, let’s make sure you get the right fit.
What Size Trampoline Is Right for You?
Trampolines come in all shapes and sizes, but picking the right one depends on who’s going to be using it and how long you want it to last. If you choose a trampoline that’s too small, your kids will outgrow it fast. If you go too big, it might take up more space than you’re comfortable with.
Below, I’ll break down the best trampoline sizes based on age, usage, and safety considerations, so you can make an informed decision. It is generally best to get the largest trampoline you can comfortably fit in your space.
Trampolines for Kids (6-12 Years Old)
✅ Best Sizes: 12ft or 14ft round or 11×8 or larger rectangle.
✅ Why? Small enough for backyard fun but provides room for growth. We always recommend that you purchase the largest trampoline that will comfortably fit your space.
✅ Weight Limit Consideration: Most support 150-250 lbs.
When you’re buying a trampoline for younger kids, you have to think ahead. Sure, an 10ft trampoline might seem fine today, but if your kids are 6 or older, you should seriously consider a 12ft or 14ft model. Kids grow quickly, and a larger jumping surface means they won’t outgrow it in a year or two.
What Size Trampoline Is Best For 2+ Kids? (We always recommend jumping 1 at a time, but we know that multiple jumpers are common)
If you have multiple kids, or they like to jump with friends, go with a 14ft or larger trampoline. The more jumping space you have, the lower the risk of mid-air collisions.
🚨 Safety Tip: Always use an enclosure net on above-ground trampolines to minimize falls. I can’t stress this enough, most trampoline injuries happen when kids fall off the edge. A strong, UV-resistant safety net can drastically reduce those risks.
Why I Recommend Larger trampolines over smaller for Most Families
🔹 An 10ft trampoline is great if you have a very small yard and only one child using it. But once you have two or more kids, they’ll be constantly bumping into each other. We always recommend jumping 1 person at a time.
🔹 A 12ft trampoline is a middle-ground option, but if you can fit a 14ft model, it’s worth the extra space.
🔹 A 14ft trampoline or 17ft trampoline will perform as your kids grow, offering more space to jump and play.
Trampolines for Teenagers & Adults
Once you start shopping for a trampoline for teenagers or adults, the size, weight capacity, and bounce quality become even more important. A too small trampoline will feel cramped, limit movement, and more importantly, increase injury risk.
✅ Best Sizes: 12ft – 14ft (Round), 17x10ft or 17x12ft (Rectangular)
✅ Why? More space to jump and higher weight capacities.
✅ Weight Limit Consideration: Ranges from 250-330 lbs (depending on model).
Round vs. Rectangular Trampolines for Teens & Adults
💡 Round trampolines (12ft-14ft) are great for casual jumping, recreational fitness, and families. They naturally direct jumpers toward the center.
💡 Rectangular trampolines (12x17ft) are better for serious jumpers, gymnasts, and athletes. The bounce is more controlled, and there’s no forced movement toward the center, which allows for higher, more consistent jumps.
Trampolines for Athletes & Sports Training
If you’re training for gymnastics, snowboarding, parkour, or any aerial sport, a trampoline can improve skill, control, and aerial awareness. Not all trampolines are built for high-performance training, so choosing the right size and shape is crucial.
✅ Best Sizes: 12x17ft (Rectangular), 14ft (Round for general fitness)
✅ Why? Rectangular trampolines provide a consistent bounce and are used by gymnasts, snowboarders, and parkour athletes.
✅ Best for: Training aerial awareness, flips, and improving balance.
Why Rectangular Trampolines Are the Gold Standard for Athletes
The reason is consistent bounce. Unlike round trampolines that push you toward the center, rectangular trampolines offer a predictable, even bounce across the entire surface. This makes them ideal for flips, spins, and controlled landings.
More, you’ll get a higher bounce. With less energy loss in the frame and springs, rectangular trampolines generate higher jumps, allowing athletes to maximize hang time and perfect tricks.
💡 Training for Real-World Application
- Snowboarders & skiers use trampolines to practice spins and flips in the off-season.
- Parkour & freerunning athletes use them to improve aerial control and landings.
- Gymnasts & divers rely on trampolines to train rotations and body awareness.
In-Ground vs. Above-Ground Trampolines: Which One Should You Choose?
When deciding between in-ground and above-ground trampolines, the choice often comes down to safety, installation, and cost. While both options can provide a great jumping experience, they serve different needs and environments.
Here’s a quick comparison to help you decide:
| Feature | In-Ground Trampoline | Above-Ground Trampoline |
| Safety | ✅ Safer (lower fall height) | ⚠ Requires safety net to prevent falls |
| Durability | ✅ Less exposure to wind & weather | ⚠ Can be stored in winter for longevity |
| Installation | ⚠ Requires digging & drainage | ✅ Easier setup (1-2 hours) |
| Cost | ⚠ More expensive to install | ✅ More budget-friendly |
Studies show Akrobat trampolines absorb 62.7% more impact than other brands, reducing strain on joints and lowering the risk of hard landings.
Making the Right Choice
Choosing the right trampoline is about more than just size—it’s about safety, durability, and long-term value.
- Bigger isn’t always better, but too small is a mistake. If you have 2 jumpers or older kids, a 14ft or larger trampoline ensures they shouldn’t outgrow it too quickly. Athletes should always opt for rectangular trampolines for better control.
- Safety should never be an afterthought. In-ground trampolines reduce fall risks, while above-ground models require quality enclosures to prevent injuries. Always check for high weight limits, strong frames, and enclosed springs to protect jumpers.
- Cheap trampolines don’t last. Many low-cost trampolines sag, rust, or fall apart within a couple of years. Investing in a well-built, high-performance trampoline means better bounce, safer jumps, and years of hassle-free fun.
