A Full Guide For Trampoline Unit Sizes

To get the most out of your trampoline unit, you will want to know which size suits you. The ideal trampoline size will be determined by the number of people using it and the amount of space available in your backyard. This article will help you find the right size for your own yard.

For many years, trampolines have provided recreation and enjoyment for people of all ages. Although they have had their highs and lows through the years, their popularity for fitness and amusement remains constant. Basically, anyone with a backyard can acquire and install a trampoline. But the wide range of trampoline sizes available in the market makes it a little bit challenging to decide on the right fit for your yard.

If you are looking for a comprehensive guide on trampoline unit sizes, you came to the right place. Before you buy a trampoline, you need to think about the size that will suit your needs. There are different trampoline sizes to choose from. You can go for a mini, small, medium, large, or extra-large trampoline. The difference between these sizes is usually the diameter of the trampoline.  The most common trampoline sizes are 7×10ft, 8ft, 8×12ft, 9×14ft, 12ft, 14ft, and 15ft.  Other than the common round trampolines, we also have oval, rectangular, and hexagonal trampolines.

So, are you in the process of purchasing a trampoline for your backyard?  We are here to provide you with everything you need to know about the different unit sizes available to help you make an informed decision.  Let us get started.

Understanding the Different Types of Trampolines

Before we dive deep into the different unit sizes, you need to know the different types of trampolines that exist and how to measure their sizes.

Traditionally, trampolines were manufactured in one shape, and only the sizes differed. However, that is no longer the case. Today, there are different trampoline shapes and sizes available in the market.

The three most common trampoline shapes you will come across are:

1. Round Trampolines

Most of us might be more familiar with the round trampolines because they are the most common. These trampolines are designed to provide a more controlled and powerful bounce capable of driving the jumper back towards the center.

Most of them require relatively less effort for more bounce and are relatively lighter compared to the other shapes. The market for round trampolines is a bit competitive, and you are more likely to find one at a more affordable price.

How to measure round trampolines

When measuring a round trampoline, make sure you start at the outer edge and measure straight across to the opposite side. From there, measure perpendicularly from top to bottom. Take the average of the two measurements to establish the actual size of the trampoline.

2. Oval Trampolines

Oval trampolines are a hybrid of round and rectangular trampolines designed to offer more freedom of bounce but with some control. Oval trampolines are more closely related to round trampolines in both construction and weight capacity.

However, they are less common and tend to be priced slightly higher than the round ones and a bit less than the rectangular ones.

Although oval trampolines are quite similar to those with round shape, they are relatively expensive.

How to measure oval trampolines

When measuring an oval trampoline, you must get the length of both sides. Start measuring at the outer edge and measure straight across the opposite side to find the width. Next, measure perpendicularly to where you just measured.

To find the depth, measure from the outer edge of one side straight across to the other side’s outer edge. Once you are through, you will have the measurement for both the width and depth.

3. Rectangular/Square Trampolines

Rectangular/square trampolines offer more freedom in the bounce areas, making them the most preferred shape for acrobats and gymnastics. They also have relatively higher weight capacities and can accommodate multiple jumpers without issues.

They are constructed of heavier materials but occupy more space and are expensive compared to the round and oval trampolines.

How to measure rectangular/square trampolines

For a rectangular or square trampoline, you will have to measure both sides. You can start by measuring the outer metal edge to find the depth before you measure straight across to the outer edge of the other side to find the depth.

Next, measure along the perpendicular side of the trampoline to find the width. Ensure you measure from the outer edge of one side to the outer edge of the other side. The measurements you obtain will be the actual size of the trampoline.

Understanding the Different Trampoline Unit Sizes Available

Now that you know the different types of trampolines available and how to measure their sizes, let us discuss some of the trampoline unit sizes available on the market.  The trampoline sizes range from toddler/baby trampolines to adult sizes.

1. Round Trampoline Unit Sizes

As mentioned earlier, round trampolines are the most common in the market. The common unit sizes when it comes to round trampolines include:

Under 8ft diameter

Trampolines that are less than 8ft in diameter are referred to as bouncers or min-tramps. Most of them are no less than 3ft in diameter and may or may not have a handrail attached.

Trampolines that are smaller in size are perfect for toddlers or kids aged from about 3 to 7 years.

Those with a handrail are known as bouncers and have a relatively lower weight capacity. Bouncers are ideal for kids aged between three and seven years.

Those without a handrail are much heavier and can be used by individuals of all ages.  The larger trampolines in this category tend to be between 5ft and 7ft in diameter and are usually enclosed with the same type of safety equipment as the larger trampolines.

8ft-12ft diameter

Trampolines within this range are considered “medium size.” They have a relatively larger jumping area, which offers jumpers the necessary space for larger children and some adults to play, jump, or do some light acrobatics.

These trampolines are ideal for single jumpers since their weight limit ranges from 175 to 250 pounds.  This is the best option for children who are over seven years old and smaller adults.

14ft-15ft diameter

The 14ft-15ft trampolines are considered large. They have a large jumping area that can allow multiple kids to play games on them. They can also accommodate several adults for play or acrobatics.

Their weight limit can go up to 500 pounds and are ideal for kids above 10 years and adults.

2. Oval Trampoline Unit Sizes

Oval trampolines are a perfect blend of round and rectangular trampolines. They can be used for all types of trampoline fun except competitive sport. They come in smaller and larger ovals.

Smaller ovals

The smaller ovals are mostly 8ft × 10ft or 8ft ×12ft. They can accommodate several kids, but their weight limit restricts adults from using them. The smaller ovals are a good fit for your backyard because they occupy a little less space than a typical 8ft round trampoline.

Their weight limit runs between 150 to 300 pounds and is ideal for kids above seven years.

Larger ovals

The most common size for large ovals is 10ft × 15ft, although some are larger. Oval trampolines in this category can accommodate multiple kids playing games or larger kids and some adults engaging in acrobatics. The weight limit of most ovals in this category is about 400 pounds.

3. Rectangular Trampoline Unit Sizes

Rectangular trampolines are best suited for use in sport and other competitive applications. They are mostly found in trampoline parks and schools and can accommodate multiple jumpers due to their spacious net and enhanced bounce attributes.

Olympic size rectangular trampolines

The most common unit size for rectangular trampolines is the Olympic size measuring 10ft × 17ft. This trampoline is specifically designed for kids over the age of seven years and light adults.  The weight limitation for Olympic size trampoline exceeds 400 pounds in most cases.

The exact dimensions of this trampoline fit the recommended specifications of the Olympic Games and world championship competitions.  It means that the trampoline can be used for other competitive sports as well.

It is best suited for kids above eight years and adults. The trampoline can also be modified beyond its original size and weight capacity.

Other rectangular trampoline unit sizes

Besides the Olympic size trampoline, there are other rectangular unit sizes available that can easily be set up in a relatively smaller backyard space. Most of them can be used in a similar manner as the Olympic size trampoline but on a much smaller scale.

Just keep in mind that the smaller rectangular trampolines are not ideal for adults since their maximum weight capacity is lower. Here are some of the common rectangular trampoline dimensions:

  • 7ft × 10ft
  • 8ft × 14ft
  • 9ft × 15ft
  • 10ft × 14ft

Most of these trampoline units are ideal for kids above seven years old and most adults. They can be used for both recreational and competitive sports purposes.

Final Thoughts

Trampolines come in different sizes, ranging from the small size designed specifically for toddlers and the extra-large ones that adults can use.  The most popular size is the 8ft round trampoline with enclosure.

It is the most sought after size because it is ideal for kids as young as three years old and can also support adults weighing up to 167 pounds.

Before you go out to purchase a trampoline for your backyard, you need to remember that choosing the right size is critical. We hope this trampoline size guide was educative and will help you make an informed decision.
