Selecting the perfect trampoline size for your family's backyard adventures or your personal fitness regimen is not as simple a decision as you might assume. It involves a range of factors such as safety, available space, user age, and the purpose of use — be it for vigorous workouts, casual bouncing, or even honing gymnastic skills.
In this comprehensive trampoline size guide, we have streamlined the complex process into an easy, step-by-step pathway to help you find that ‘just right’ trampoline. From scrutinising different dimensions to understanding the nuances that each size brings to your bouncing experience, we are here to provide a handy roadmap.
Let’s bounce right in to ensure your next purchase brings home not just the best trampoline but endless bounds of joy and satisfaction.
Trampoline Sizes and Dimensions
Trampolines are typically measured in feet or metres, and this measurement refers to the frame size, not the mat size. Here's the difference between the two:
Frame Size vs. Mat Size
The frame size is obtained by measuring the outer edge of one side of the trampoline to the outer edge of the opposite side, encompassing the entire width of the trampoline, including the frame and springs.
This is a crucial detail as a 3-metre trampoline doesn't mean you get a 3-metre diameter bouncing area; the actual jumping surface will be less, factoring in the width of the frame and springs.
Meanwhile, the mat size refers to the actual jumping area available. To get the mat size, you would measure the space inside the trampoline frame from one side of the mat to the other, excluding the springs and the frame.
Measuring Trampolines of Different Shapes
It is important to note that trampolines come in different shapes, each having its own method of measurement. Understanding this should help you visualise how much space the trampoline will occupy in your yard.
- Round trampolines are measured by their diameter, which is the distance from one edge of the frame directly across to the other edge.
- For rectangular trampolines, both the length and the width are measured, i.e., the longest and shortest sides of the frame, respectively.
- Oval trampolines: For oval trampolines, you need to measure both the longest and shortest diameters to get the precise dimensions.
Don't forget to factor in the weight limit of your trampoline. It's essential to choose a trampoline that can safely support the combined weight of all users to ensure safety and longevity.
Finding the Best Trampoline Size for Your Space

Typically, trampolines are classified into small, medium, large, and extra-large (pro category) sizes, each having its distinct advantages and catering to different needs and spaces. Below, we go over the specifics to help you pinpoint the best fit for your needs.
#1 - Small Trampolines
Mini trampolines or rebounders typically have a diameter of about 90 to 102 cm or approximately 1 m. This also depends on the brand and the amount of space available at home. For instance, trampolines size up to 10ft are generally considered small/medium, and 10-12ft trampolines are considered medium/large.
Small trampolines are compact and easy to fit in indoor spaces or small yards, offering a great solution to keep little ones entertained and active. Despite their small size, they pack a punch when it comes to the joy and excitement they can bring to toddlers and young kids, fostering a love for physical activity early on.
Note that these trampolines may offer limited bouncing space, which might restrict the kind of activities and games that can be played, potentially reducing the longevity of interest in older kids.
#2 - Medium Trampolines
Medium-sized trampolines are around 3.2 m (generally anywhere between 8-12ft) in diameter. They have a good balance between size and functionality, offering a generous space for bouncing and ensuring teens can have fun without feeling cramped. They also accommodate a variety of trampoline activities and games, promoting hours of enjoyable physical play.
Though medium-sized trampolines offer a more spacious bouncing area compared to small trampolines, they are still restrictive for adults or more advanced trampoline maneuvers, so keep the user's age and skill level in mind.
#3 - Large Trampolines
Large trampolines have an average diameter of 12-16ft. They are designed to offer expansive bouncing areas, suitable for adults and those who are into serious gymnastics training. The spacious surface allows for a greater variety of trampoline exercises and ensures that you can comfortably share the bouncing space with others, making it a centre for family fun and fitness.
Nevertheless, be cognizant of the fact that large trampolines require substantial yard space, possibly limiting the functionality of your outdoor area for other activities. Ensure you have enough room to accommodate one while still being able to enjoy other backyard pursuits.
#4 - Extra Large Trampolines
The pro-category trampolines are the giants in the field, promising unparalleled space and bounce. They are the go-to choice for professional gymnasts and trampoline enthusiasts seeking a high-performance trampoline for advanced training and tricks.
Typically with a diameter above 16ft, extra-large trampolines not only meet the standards for professional practice but also bring an amusement park vibe right to your backyard, promising unmatched fun and excitement.
But just like large trampolines, they require a larger space and also come with a heftier price tag. They may also be overwhelming for younger children if you're considering it for your backyard. Thus, it is crucial to carefully evaluate the age and skill levels of its potential users.
Trampoline Size Chart
Here is a handy chart that classifies trampolines based on their shape, measurements, and recommended size categories:
Size |
Dimensions | Activities | Space |
---|---|---|---|
Small | Up to 2.44m / 8ft | Basic bouncing, toddler games | Indoor spaces, small yards |
Medium | 2.44m - 3.66m / 8ft - 12ft | Bouncing, beginner tricks | Medium-sized yards |
Large | 3.66m - 4.88m / 12ft - 16ft | Aerobic exercises, intermediate tricks | Large yards |
Extra Large | Above 4.88m / 16ft | Advanced acrobatics, professional training | Very large yards, professional training spaces |
The classifications in this chart are based on industry standards that are widely accepted across the trampoline manufacturing and retail industry globally. They are drawn from market research and feedback from users, aiming to help you easily identify the right category that meets your needs. However, they may vary from brand to brand.
Trampoline Size and Important Safety Considerations

When choosing the optimal trampoline size, you cannot overlook safety. Different size categories not only offer distinct bouncing experiences but also carry with them unique safety considerations. Here's everything you should know.
Small and Medium Trampolines
Small to medium-sized trampolines are more controlled environments, making them a safer option for younger users and beginners. They offer limited bouncing space, which inherently reduces the risk of high-impact collisions and falls.
We do not advise that small children, including toddlers, use a trampoline due to their higher risk of getting injured. Kids ages 6 and older can jump on a small-sized trampoline but be available to provide the necessary supervision.
Ensuring safety also extends to the space around the trampoline. One sure way around this is to create a safety perimeter of at least 2.5 m around the trampoline to prevent injuries from falls and jumps that may extend beyond the trampoline's edge.
Large and Extra-Large Trampolines
While large and extra-large trampolines offer an expansive bouncing area, they bring along an increased risk of injuries due to the higher jumps and tricks that can be performed on them. We recommend installing safety nets and padding, irrespective of the trampoline size, to mitigate the risk of accidents.
Using Safety Nets and Padding
Safety nets are an indispensable accessory for trampolines of all sizes, as they act as a barrier to prevent falls and accidents. Padding, on the other hand, provides a cushioning effect on the springs and the frame, reducing the impact of accidental falls.
However, a study published in The Australian and New Zealand Journal of Public Health concluded that safety nets may give a false sense of safety to the parents and hence result in lesser supervision of children while they are using the trampoline.
Always prioritise safety while enjoying your trampoline. Remember, no accessory replaces active, attentive supervision. Stay safe, and enjoy bouncing responsibly.
What Size Trampoline Should You Buy?
Having considered all the necessary bits about trampoline sizes and safety measures, here are 5 important considerations to help you make an informed decision in your trampoline purchase:
#1. User Age and Skill Level
Begin by considering the age and skill level of the intended users. Smaller trampolines are suitable for younger children, providing a safer environment for them to play in. As the age and skill level increase, you may consider medium to large trampolines to offer a more expansive bouncing area, facilitating a wider range of activities, including advanced aerobics and acrobatics.
#2. Intended Use
Are you looking for a trampoline mainly for recreational purposes, or is it going to be a part of a rigorous fitness routine? Smaller trampolines are great for casual bouncing, while larger ones can support more vigorous workouts and professional training.
#3. Spatial Considerations
Keep in mind the available space in your yard. Always adhere to the safety guideline of maintaining a 2.5-metre buffer around the trampoline to ensure safety. Hence, measure your space accurately and choose a size that not only fits but also allows for safe use.
#4. Budget
Your budget is an unavoidable factor in your decision-making process. Generally, larger trampolines come with a heftier price tag. However, it is advisable not to compromise on safety and quality for the sake of saving money. Ensure to purchase from reputed brands that adhere to Australian safety standards to get the best value for your money.
#5. Assembly and Maintenance
Larger trampolines require more effort in assembly and maintenance. Consider the ease of assembly, availability of replacement parts, and the warranty period offered by the manufacturer while choosing the size.
Trampoline Accessories to Enhance Your Experience

When choosing the perfect trampoline size for your space, it's also wise to consider the range of accessories available that can augment your bouncing experience and add an extra layer of safety. Let's delve into some popular accessories that are both fun and functional:
Safety Accessories
- Safety Pads: These are designed to cover the springs and frame, providing a soft landing in case of falls and preventing injuries from the hard metal parts of the trampoline.
- Ladder: A trampoline ladder facilitates easy access to and from the trampoline, especially for younger kids, ensuring safety while climbing on and off.
Fun Add-ons
- Basketball Hoop: Attach a basketball hoop to your trampoline to introduce a sporty, competitive edge to your bouncing sessions. It’s a great way to encourage physical activity and fun, especially among children and teenagers.
- Tent: If you have the space, a trampoline tent can transform your trampoline into a fun play zone or a cozy retreat, adding a new dimension to your outdoor activities.
- Sprinkler: A sprinkler system can be attached to the trampoline, bringing refreshing fun during hot summer days and adding a splash to your bouncing adventures.
Maintenance Accessories
- Weather Cover: Protect your trampoline from harsh weather conditions and increase its lifespan with a weather-resistant cover designed to shield the mat, springs, and frame from rain, sun, and snow.
- Anchor Kit: To safeguard your trampoline from strong winds and storms, consider investing in an anchor kit that secures the trampoline firmly to the ground, preventing it from being blown away in adverse weather conditions.
When buying accessories, make sure to choose those compatible with your trampoline's size and shape to ensure a seamless fit and function. It's best to refer to your trampoline's user manual or consult the manufacturer for guidance on compatible accessories.
