How to Choose the Right Trampoline Size for Your Backyard?

If you’re looking to buy a trampoline, you have many choices. You’ll have to decide on things like size, shape and brand. When making these decisions, your safety and the safety of your family will be a top priority. This article will help you to determine which size is best for your family, as well as other factors that will contribute to the overall enjoyment of your new backyard trampoline.

Consider the Size of Your Backyard

Consider the Size of Your Backyard

The size of the trampoline you choose is dependent on a few factors. The most obvious of these is the size of your backyard. If you have only a small yard, it may not make sense to buy a large or extra-large trampoline.

Frankly, even if you have an enormous backyard, a jumbo-sized trampoline may not be right for your family. Many adults do not have the upper-body strength to perform flips and other tricks on such a large apparatus.

It’s also important to consider where you plan to store your trampoline during the off-season. If you don’t have much space available, a smaller model may fit better in your shed or garage.

Know Who Will be Using the Trampoline

The best way to determine which size is right for your family is to think about how many people will use it at one time. For example, if you plan on using your trampoline with several children at once, you need a larger model so everyone has enough room to jump safely and avoid injury.

Double Check The Weight Limits

Also remember that the weight limit for each jump spot differs among models, so if several members of your family feel like making simultaneous jumps, you need to purchase a larger model with more weight-bearing support.

Standard Trampoline Size


You may wonder, what is the standard size of the trampoline?

A standard trampoline can range from 8 feet to 15 feet. A little bigger, you will go beyond the standard range. A little smaller, you will enter more children or sports trampolines. The average size of a trampoline is usually 12 feet.

The smallest size for a standard trampoline is 8 feet by 8 feet (64 square feet). That’s too small for more than one adult or one or two kids, but it can work if there’s not much room in your backyard.

If you want to let more people jump on at once, consider buying a 12-foot trampoline (120 square feet).

The biggest size for a standard trampoline is 15 feet by 15 feet (225 square feet). That’s large enough for two adults to jump on at the same time. You can also use this size for younger kids or teens. But if you’re buying a trampoline specifically for children, experts recommend that you get one with a diameter of at least 36 inches.

Average Trampoline Sizes

  • 8 – 10 Ft Round Trampoline: Perfect for smaller backyards.
  • 12 Ft Round Trampoline: Medium sized trampolines.
  • 14 Ft Round Trampoline or more: More flexibility and for older users.

How Big is a Full Size Trampoline?

A full size trampoline is perfect for the whole family. This is definitely one of the best ways to exercise and have fun outdoors. A full size trampoline will provide you the maximum amount of fun and enjoyment while keeping you fit.

The standard size of a full size trampoline is 8 x 10 feet. The recommended distance between the frame supports is 7 feet and the recommended distance between the outside edge of the jumping mat and the frame is 2 feet. These measurements are important as they ensure safety for jumpers, especially when more than one person uses the trampoline at a time.

A full size trampoline is ideal for kids aged 3 to 10 years old because it provides plenty of space for them to move around without hurting themselves on any part of the frame or springs. Some brands also offer different shapes that can accommodate more people on certain models such as heart-shaped or star-shaped rings.

How Tall is a Trampoline?

For small trampolines of 6 to 8 feet, the height of the trampoline from the ground is usually about 2 feet. The large trampoline is about 3 feet above the ground. The total height of the small trampoline is about 6 feet, including the safety fence, up to 8 feet.

Remember to Choose a Trampoline that’s Right for You

It is important to buy the right size trampoline for your children.

Why? Injuries on Trampolines

Many people have said that injuries are more common on larger trampolines. Large trampolines are harder to jump on and off of, making it easier to trip or fall off. They have more springs, which increases the risk of injury. And they could tip over easier, sending a child flying into something solid like a wall or the corner of a room.

What Size Should You Get?

A good rule of thumb for determining what size you should get is: the age (in years) plus one equals how high your trampoline should be off the ground.

For example, A six-year-old would need a 7’ high trampoline, while a seven-year-old would need an 8’ high one. However, if it is just one person using it, you should add about 2 feet to that number for safety reasons.

How to Measure Round Trampolines

You need to measure from edge to edge. You will want to start on one side of the frame and then end on the other side of the frame. This way you can get an accurate measurement.

Calculate the diameter of the trampoline by measuring from one outside edge to the opposite outside edge. This is probably the most important measurement to take. The diameter determines how many people can use your trampoline at one time (maximum weight capacity).

Divide the diameter measurement by 1.32 to calculate how many square feet of bouncing area you will have per person (for example, if you have a 12-foot round trampoline, each person will have approximately 9 square feet available).

How to Measure Rectangular Trampolines

Most rectangular (oval) trampolines are 10 feet in length and at least 8 feet in width. They usually don’t come with a center safety pad, so you’ll need to measure by adding 8 more inches to the length and width of the trampoline frame. If your rectangular trampoline has a handle attached, add an additional 8 inches to those measurements as well.

When choosing your trampoline size, you should therefore consider the specifics of your backyard and family. You should also determine what your immediate goals are: do you want something big enough to fit a few kids at once, or would you prefer just a small, personal trampoline? Whatever your decision, be sure to research the trampolines that interest you most before purchasing.
