What Size Trampoline Should You Get?

For most people, it takes little thought about whether or not they should get a trampoline.

Honestly, trampolines are a blast to have and everyone who has ever been on one has had so much fun on it.

So when the question is asked “what size trampoline should I get?”, there are a few things to consider. This includes what are the ages of the people jumping on the trampoline, how many people will be jumping on the trampoline, and what size is the yard I want to put the trampoline.

If you consider these questions and read the below, you should be able to tell what size trampoline you should get.

Why get a trampoline

Before considering what size trampoline you should get, consider why you are getting a trampoline.

Trampolines are fun for people of all ages, from the toddler looking to burn off some energy, to the elderly who are looking to get themselves up off of the ground.

Trampolines bring people the kind of joy that you can hardly find anywhere else.

Trampolines are good for wearing down your kids before you go to bed, good for teenagers who are looking to have a few friends over for a fun evening.

There is very little you cannot do with a trampoline.

What are the ages that will be jumping

First, you need to consider the ages of the people that will be jumping on your trampoline.

While a giant trampoline might be fun for little kids, it is not recommended that a child younger than 6 years old jump on a regular trampoline (9 feet or larger).

According to the Mayo Clinic:

Limit trampoline activity. Don’t allow a child younger than age 6 years to use the trampoline.

This recommendation is in place because children at 6 years of age or younger do not have full control over their body and can easily get hurt on a trampoline that is too big for their size.

At that age, you should consider an “exercise” trampoline, which is one that is smaller than 7 feet in diameter.

Not nearly as fun as a regular size trampoline, but still allows the toddler to have some fun.

If the ages of the people jumping on the trampoline are going to be 7 years old and older, a regular size trampoline is going to you just fine.

TrampolineHacks.com has a helpful table to help you see what size trampolines should get based on the age of people jumping:

Age CriteriaTrampoline Sizes
Toddlers and Younger Kids 10 Months to 5 YearMini-Small Trampolines 36 inch, 38 inch, 40 inch, 48 inch, 55 inch, 3 feet and 7 feet
Elder Kids and Adults 6 Year and OlderSmall, Medium and Full Size Trampolines 8 feet, 10 feet, 12 feet, 14 feet, 15 feet, 16 feet and 17 feet
Only AdultsFitness Trampolines (Rebounders) Up to 3.5 feet with handle bar

How many people will be jumping

Consider how many people will be jumping on your trampoline.

In our family, all five of our boys like to jump at the same time.

And sometimes they can manage to get one of their parents involved as well.

So, in our case, we can have upwards of 6 to 7 people jumping on the trampoline.

With seven people, a trampoline between 7-12 feet is probably not going to cut it.

A trampoline 13 feet in diameter or above will probably be just perfect for that number of people.

A 14-foot trampoline from Skywalker Trampolines might be just the right trampoline for that need.

With people also comes weight.

Six to seven people, with two adults, means we have at least 500 lbs jumping on the trampoline.

Most trampolines you can purchase are going to have a maximum weight limit allowed.

The Skywalker trampoline listed above is rated at 250 lbs per jumper, with a maximum weight of 1,000 lbs.

So consider how much weight you are going to put on the trampoline before you purchase and check the weight limits on your preferred trampoline.

What size yard do I have

In this case, you not only have to consider how big the trampoline is going to be, but how much space you will need around it.

According to TurfMechanic.com

The space available in your yard needs to be level, free of branches & fences and should allow a clearance of approximately 5 ft around all sides to provide ample space. With these guidelines, you should be able to determine the maximum size trampoline your yard can accommodate.

For example, if you are looking to buy a round trampoline with a 10 ft diameter, then you need a clear, level area with about 20 ft diameter. If you are looking into an 8 x 12 ft rectangle trampoline, then you need an area of 18 x 22 ft to properly accommodate it.

So make sure you have 5 feet of open space all around the trampoline.

Especially make sure that there are no tree branches or fences in the area you want to put the trampoline.

In the example above, if you are considering an 8 foot by 12-foot trampoline, make sure you have 18 feet by 22 feet of space in your yard.

If you do not have that much space, find another space in your yard that might better accommodate the trampoline.

Also, take into account that you need flat ground to put your trampoline on unless you want to spend some time digging trenches.

What shape of trampoline do you want

There is a pretty standard shape for a trampoline, but that does not mean there is only one shape.

Here are the different trampoline shapes you might consider.


The round trampoline is the standard trampoline shape.

Most, but not all, trampolines you find will be this shape.

It is good for bounce and also for safety.


Rectangle trampolines are known for getting more bounce than their round counterparts.

These trampolines are good for multiple people and if people want to do tricks, like flips, the longer shape of the trampoline allows more space for jumping and flipping without getting injured.


Oval trampolines are great because they have more than one “center” point of the trampoline, allowing more than one person to get a good bounce.


A square trampoline has less bounce than the other trampolines, so they might be safer if you have younger children who will be bouncing.

You can also find square trampolines that come with fun accessories like basketball hoops.

Square trampolines also come in larger sizes, like Olympic size trampolines, so they can accommodate larger group sizes.

Put all your data together to make a decision

Once you know how many people will be jumping, what the max weight for the jumpers is going to be, and how much space you have in your backyard, it should make deciding on a trampoline much easier.

You have a few trampoline distributors to choose from:

Skywalker Trampolines

Skywalker trampolines are a little bit cheaper than most trampolines available.

That does not necessarily mean that they are a lower quality option.

They are good as started trampolines so you can try out the size and make sure it is a good fit for your family and needs.

Springfree Trampolines

Springfree trampolines are a relatively new kind of trampoline that does not have springs.

It actually uses flexible composite rods in place of springs and places the rods underneath the trampoline mat.

This makes it more safe for the jumper.

Springfree trampolines are a bit more expensive than regular trampolines, so it would be more of an investment for your family.


JumpSport has a few different offerings for trampolines, including the AlleyOOP, which gives a great bounce, but also a soft landing.

They also the Elite, which also gives a softer landing on the trampoline mat.

So if you are worried about kids getting hurt from landing on the trampoline mat, the JumpSports might be a good trampoline for you and your family.

It will be a little more expensive than regular trampolines as well, so if you decide on this one, it will be an investment.

There are other trampoline distributors to choose from, but the above are just a few that I am familiar with.


So figure out the number of people you think might be jumping on your trampoline and what the weight limits might be.

Make sure your yard will accommodate the trampoline size you are looking at.

Then go forth and purchase your trampoline.
