One of the biggest dilemmas people have when choosing a trampoline is to find out which trampoline sizes are the best ones for our yard and our family. The greater the choice you have, it can feel like the harder the decision.
Choosing the right trampoline size depends on a number of factors, including what it’s going to be used for, who’s going to be using it and where it will be situated. Then there’s the height of the trampoline plus the enclosure, which is always needed when children are bouncing.
We’ve put together this handy guide to trampoline sizes to help you choose the right size of trampoline that will last you a lifetime. If you want, you can also find your perfect trampoline here to see which model suits your family best. Read through or skip to what applies to you:

Why trampoline sizes matter
We regularly get asked the question, ”Can’t I just choose a trampoline size that fits my garden/backyard?” Technically, you could but that doesn’t mean you’ve chosen the right size in terms of how the trampoline will be used, who’s going to be using it, and doesn’t take into consideration the height or the safety aspects.
At ACON, we have a long-standing philosophy that one trampoline should last you for decades. Our ACON for Life mantra is locked into the way we design our trampolines. We make sure that the one you choose will not only be used for a long time, but be with you for a lifetime – although we do admit that you may need to replace parts sometimes if they become worn or damaged.
Trampoline sizes for kids
When looking at trampoline sizes for kids, all shapes and sizes are safe for kids to use, even the smallest of children. However, it is an absolute must to add a trampoline enclosure for safety, particularly if smaller kids will be jumping.
Our most popular model for kids, particularly those just starting out in their trampolining journey, is our beginner-friendly ACON Air 2022 10ft trampoline which comes with a standard enclosure for safety and a ladder. Overall, round models are suitable for beginners (which most kids are) as they direct the jumper to jump in the middle of the trampoline.

Don’t forget to measure not only the height of the trampoline but also add on the height of the enclosure. Check where you will be putting the trampoline and make sure there are no trees or other obstacles that may be in the way.
Trampoline sizes for teens
When it comes to choosing a trampoline size for teenagers, it really does come down to what they want to do on the trampoline. If they are looking to just enjoy bouncing with friends and family, our 12ft trampoline or 14ft trampoline are great options depending on the size of the yard.
However, if they want to do tricks and more advanced jumps, they will need enough space with premium bounce experience that our trampolines offer. The mat size is also something to consider in case the teens are interested in add-ons, such as basketball hoops and trampoline scooters.
At ACON, our options for teens are our bigger round trampolines. A trampoline 4.3m in size offers plenty of space for jumps, leaps, and even tricks, while the 4.6m model provides even more room for advanced users.
Trampoline sizes and types for tricks
Although most ACON trampolines provide sufficient bounce for vaulting and practicing tricks, our two best-selling trampolines, which are loved by the tricking community worldwide, are our flagship models 16 HD and the smaller version, 13 HD. These trampolines are now also available for pre-order with our brand-new Performance Piano Wires. These springs will take you to new heights while letting you experience the softest of bounces in the market. A top choice for tricksters and gymnasts!
Our rectangular models provide more even bounce compared to our round trampolines. In other words, the bounce is similar no matter where you jump on the mat. Which size you choose depends on the size of your garden or backyard, and your preference. They are great for tricks, flips and tumbling, as well as being the perfect trampoline for gymnasts and vaulters.
Trampoline sizes for adults and family
By default, all our trampolines are designed for family fun, thus the trampoline sizes for adults and for family use are similar to those you would choose for kids and teens in that it depends on the intended usage.
In our experience, families tend to choose a big trampoline such as a 14ft, 15ft, or 16 HD model, since parents often prefer more jumping space for themselves and growing children.
Backyard trampoline sizes
For people who are looking for trampoline sizes for their backyard, rather than a larger garden, the size of your backyard is essential.
Here are our recommendations for trampoline sizes in various yards:
| Yard Size | Trampoline sizes (round) | Trampoline sizes (rectangular) |
|---|---|---|
| Small yard | 6ft model & 10ft model | |
| Medium yard | 12ft model | 13 HD |
| Big yard | 14ft & 15ft model | 16 HD |
The shape of the trampoline has an impact. If you have a square shaped backyard, you will need a rectangular trampoline; a backyard with rounded corners will better suit a round trampoline.
Before you make a purchase, take the measurements of the trampoline of your choice and add an additional 3ft (1m). This is because you must have at least this distance around the entire trampoline for safety.
Whilst you’re measuring your backyard and garden to determine which trampoline size you should choose, don’t forget to measure the height, including the enclosure. Also, when evaluating the space for the trampoline, kindly note that there should not be anything under the trampoline as that could precede a safety risk.
Trampolines for indoors
If you’re looking for mini trampolines for indoor use, our ACON FIT trampolines in round and hexagon shapes are ideal. When it comes to our regular trampolines, the Baby ACON is the best choice to be used indoors.
Regardless of which indoor trampoline you opt for, make sure you have plenty of free space around you and enough height before you start jumping.
Travel size trampolines
Whether you are a regular traveler or a trickster wanting to shoot videos of your latest tricks in a stunning location, our Baby ACON is the perfect choice to take with you. Its compact size belies one of the best bounces in trampolines.
It features our new Air Series springs, as do all our trampolines, and our patented Synergy Design. We’ve added a high-quality padding that is thick and soft and is fully UV protected. The Baby ACON is easy to assemble and disassemble, making it easy to take with you just about anywhere.
If you are a professional, amateur or up-and-coming trickster, keep your eyes open for something exciting coming in the very near future!
Cost considerations when choosing your trampoline
Just a few points to remember when choosing trampoline sizes:
- The bigger the trampoline, the more it will cost.
- Size isn’t the main factor when considering the cost – quality is.
- The shape influences the price – rectangular is more expensive than round as it requires more materials to produce it.
- The price of trampolines is directly related to the quality of the materials, rigorous testing and other aspects rather than the trampoline size alone.
So, remember that the price should be just one of the factors you consider. If interested in learning more, read more about the trampoline cost in our blog post.
Tip: if you are not sure which to select between two sizes, choose the bigger size; you’ll be less likely to regret this choice.

Frequently Asked Questions
How tall is a trampoline?
The height of a trampoline varies depending on the model and whether it includes a safety enclosure. Typically, trampolines stand about 60 to 90 cm high from the ground to the jumping surface. With a safety enclosure, the total height is usually between 1.8 and 3 metres.
What are the different trampoline sizes?
Trampolines come in a wide range of sizes to suit different needs and spaces. Small trampolines are typically between 110 cm and 1.8 metres in diameter. Medium-sized models are usually around 3.7–4 metres, while larger trampolines generally range from 4.3 to 5.2 metres.
What size trampoline do I need for exercise?
It depends on what kind of exercise we are talking about. The ACON FIT - round at 44in, as well as the ACON FIT - hexagon at 55in are specifically made to accommodate for fitness and yoga exercises indoors, even during more intense workouts. For both indoor and outdoor options there is the Baby ACON, with a compact and transportable 1.8m design. You can always size up if you want a different type of workout, but the ACON FIT - models are your best bet for doing exercise.
What are the most common trampoline sizes available for backyard use?
The most common backyard trampoline sizes range from 3 to 4.6 metres. Smaller 3-metre models work well for younger children and compact yards, while 3.7 to 4.6-metre trampolines are popular for families, teens, and more active jumping. Rectangular trampolines are also commonly chosen for tricks, gymnastics, and advanced bouncing.
What size trampoline is appropriate for a family with young children?
For families with young children, 3-metre and 3.7-metre round trampolines are often a great choice because they provide enough jumping space while fitting comfortably into many backyards. Round trampolines are also considered beginner-friendly since their shape naturally guides jumpers toward the centre of the mat.
