For decades, trampolines have provided recreation as well as sport for people of all ages. Though they have had stronger and weaker trends over the years, their popularity for amusement and fitness has remained constant. Essentially, the potential exists for anyone with a backyard to also have a trampoline. The wide variety of trampoline sizes is what makes this possible, but the wide variety also makes it a little bit more difficult to decide on the right fit for your yard as well.
Our trampoline sizes guide can help you determine which style and size of trampoline is most likely to fit the dimensions of your yard as well as your needs and the needs of your family. We’ll look at different types of trampolines, how they are measured, their various sizes and how each is best used. After using our sizing guide, you will have the necessary information to narrow you choice of the right trampoline to a particular size before making your purchase.
What types of trampolines are there?
Traditional trampolines were more or less one shape though they varied some when it came to size. That is no longer true where trampolines are concerned. There are several shapes and types of trampolines available today. Here are the three that are most common and some of their basic attributes:
• Round. These trampolines tend to provide a more controlled bounce that drives the jumper back toward the center. They tend to require less effort for more bounce and their weight capacities tend to be a bit lower. There is a very competitive market for this style of trampoline and you are more apt to find it at a more affordable price.
• Rectangular. There is more freedom in the bounce of these trampolines, which causes them to be preferred by gymnasts and acrobats. They tend to have higher weight capacities and accommodate multiple jumpers. They are built of heavier materials, take up more space and tend to have a higher price tag attached to them.
• Oval. Trampolines of this type are a hybrid of the two, allowing for a little bit more freedom of bounce, but with some of the control of the round style. They tend to be pretty closely related to round trampolines in weight capacity and construction, but because they are a little less common, they tend to be priced a bit higher than the rounds and a bit less than rectangular trampolines.
Though there are other shapes such as squares and octagons, the three types above are the most common. Each have their pros and cons when it comes to the required dimensions necessary for safely using them, which we will discuss in greater detail after we take a look at how trampolines are measured.
How are trampolines measured?
The measurements of a trampoline are pretty straight forward whenever you talk about the dimensions from the extent of the frame, but there is a little bit more to the measurement of a trampoline than just its structural dimensions. Let’s take a closer look at how trampolines are measured and how much space you will need to accommodate one.
Circular trampolines have pretty straight forward measurements. A circular trampoline is measured from the extents of its frame across its diameter. This is the measurement referred to when purchasing a particular size of trampoline and does not refer to the jumping area or jumping matt dimensions. In addition to this measurement is a clearance measurement or area around the trampoline that should be free of other objects that might jeopardize the safe use of the apparatus. This measurement typically extends an additional two feet beyond both outer edges of the frame. Here is a quick example of the space needed for a 15’ round trampoline:
Outer edge diameter is 15’
Safe clearance diameter is 19’
You will need 19’ of clear space available in all directions to safely install and use this trampoline.
A rectangular trampoline is also measured from the extents of its frame in both width and length. Width is measured across its narrowest dimension and length is measure along its longest dimension. A rectangular trampoline is labeled as width x length, like 10’ x 17’. When the safety clearance is added, just as it is with round trampolines, the available space is increased by two additional feet on all four sides. Therefore, a 10’ x 17’ rectangular trampoline will need an available area of 14’ x 21’ to safely install and use it.
Oval trampolines are measured similar to rectangular trampolines and labeled with a width x length size. They are measured across their narrowest dimension to provide a width measurement and along their longest dimension to provide a length dimension. However, an oval trampoline can save a little bit of clearance space, which is why they are sometimes chosen, because the two feet of added clearance space on the ends are calculated along the radius of their circular ends rather than the square area of their outer dimensions.
In the case of most outdoor trampoline installations, height is not a concern. However, you need to be aware of any electrical, telephone, television or other wires that might be above the trampoline. If one or more of these are present in the area you have measured out for installing your trampoline, you will need to relocate the unit to eliminate the danger of that hazard unless it is far above the rated jumping height of the trampoline. If you are installing the trampoline indoors, be completely certain that the vertical space will accommodate the height jumping height of the trampoline as well.
Now that you understand how trampolines are measured and the space necessary to safely accommodate their installation and use, let’s take a look at the various sizes of different types of trampolines and their best use.
Various Trampoline Sizes
As we mentioned earlier, round trampolines are the most popular type or style of trampoline on the market and there is pretty stiff competition when it comes to their production and marketing. Consequently, there is a wider variety of dimensions and accommodations available as well.
Under 8’ diameter
Trampolines under eight feet in diameter are typically referred to as mini-tramps or bouncers. These trampolines are typically no less than 3’ in diameter. They may or may not have a handrail attached to them, depending upon their use. Those with a handrail tend to be called bouncers, have a lower weight capacity and are used by children between 3 and 7 years of age. Those without a handrail tend to have a heavier weight capacity and can be used by individuals of all ages for fitness purposes.
Larger trampolines in this class tend to be between 5’ and 7’ in diameter and are enclosed with the same type of safety equipment as larger trampolines. The weight limits on these trampolines tend to run between 100 and 150 pounds, which exclude them from being used by larger children and adults, but accommodate children between 3 and 7 years of age.
Best Use: children 3 to 7 years (indoor and outdoor models) or adult fitness with some specific models.
8’ to 12’ diameter
This range of trampolines is considered medium sized trampolines. Their larger jumping area provides the necessary space for larger children and some adults to jump, play or do acrobatics. They are better suited for single jumpers, especially when used by larger children or adults. Their weight limits run in the range from 175 to 250 pounds though some range a bit higher.
Best Use: children over the age of 7 and smaller adults for recreational use
14’ and 15’ diameters
These are considered large trampolines. Their jumping area allow for multiple children to play games on them and for larger adults to jump, play or do acrobatics. Their weight limits are commonly above 200 pounds and go up to 400 pounds.
Best Use: children over the age of 7 as well as most adults for recreational use
Rectangular trampoline sizes are not as numerous as round style trampolines. There use is better suited for sport and competitive applications. They are often found in schools or in trampoline parks. They tend to allow for multiple jumpers due to their space and bounce attributes.
The most common size of rectangular trampoline is Olympic sized or 10’ x 17’. This size of trampoline is for children over the age of 7 years of age as well as adults. The weight limitations of these trampolines typically exceeds 300 pounds and is often much higher. The dimensions of these trampolines fits the specifications of the world championships and Olympic games competitions as well as other competitive sports played on trampolines.
Best Use: children over the age of 7 and adults for recreational or competitive use (depending on additional specifications beyond size and weight capacity).
Other Rectangular Sizes
There are several other rectangular sizes available which allow them to be set up in a smaller backyard space. These trampolines can be used in similar fashion to Olympic sized trampolines, but on a smaller scale. Those of smaller dimensions tend to be less accommodating for larger adults when it comes to weight capacity, so their use may be limited to certain adults and older children. Here are some common rectangular trampoline dimensions:
• 7’ x10’
• 8’ x 14’
• 9’ x 15’
• 10’ x 14’
Best Use: children over the age of 7 and most adults (dependent upon weight capacity) for recreational use
Oval trampolines have similar properties to both rectangular and round trampolines. Consequently, they can be used for various types of trampoline fun except competitive sports. They allow for greater controlled bounce with less effort on the ends and more space and freer bounce in the middle.
Smaller ovals run in sizes like 8’ x 10’ or 8’ x 12’. They can accommodate multiple jumpers or players when it comes to children, but their weight capacities limit the use of adults or larger children. They are a good fit in a backyard that can allow for a little bit more than a typical 8’ trampoline. Their weight limits run between 150 to 250 pounds.
Best Use: children over the age of 7 and smaller adults for recreational use
Though there are larger ovals on the market, the most common size of oval trampoline is 10’ x 15’. This accommodates multiple children playing games or larger children and adults engaging in acrobatics. The weight limits on this larger oval runs up to about 300 pounds.
Best Use: children over the age of 7 and most adults for recreational use
When it comes to selecting the right trampoline to fit your backyard and to accommodate the needs of your family, the size of the trampoline has a great deal to do with whether or not it will fit as well as what activities can be enjoyed on it. Measuring your yard for the installation of a trampoline needs to take in both the dimensions of the trampoline itself as well as the area of safe clearance around the outer edges. In addition to the horizontal dimensions of your trampoline, do not forget to take height clearance into account to avoid any accidents that might come from overhead wires and cables.
With the right dimensions and the proper, safe use of each size of trampoline, you can provide plenty of amusement for your family as well as a number of benefits to their health and fitness. Making use of our trampoline sizes guide, you should be well qualified when it comes to making a purchasing decision of the right trampoline to fit your backyard.
