What Size Trampoline Do You Need? (Honest Advice) 

Have you been asking yourself, “What size trampoline do I need?” 

This is one of the most common questions consumers have when searching for a trampoline, and it’s an important one. 

Buying the wrong-sized trampoline could result in a few things, none of which are ideal: 

  1. A trampoline that doesn’t fit in your backyard.  

  2. A trampoline that cannot safely handle the weight of the jumpers.  

  3. A trampoline that your child grows out of and not into.  

  4. A trampoline that has limited space to jump or perform tricks. 

We’ve crafted this article so that these unfortunate consequences do not become a reality for you.  

At Springfree Trampoline, we believe that trampolines should consistently provide joyful moments, not headaches. We created the springless trampoline and have spent decades helping consumers figure out the right size of trampoline to buy. 

We’re going to use that knowledge to give you objective guidance on which size of trampoline you should buy. 

We’ll start by going over the different types of trampoline sizes you can buy before going into detail about how to choose the right size trampoline for you and your family.  

After reading this, you should feel completely confident in making an informed decision on the trampoline size you need for your situation. 

The Different Types of Trampoline Sizes

3 Steps to Choosing the Right Trampoline Size 

Now that you’ve learned about the common sizes for an outdoor trampoline, let’s now get into the steps for choosing the right size for your backyard: 

  1. Measure Your Yard 

The first step that must be completed before anything else when figuring out which trampoline size to go with is measuring the size of your yard. 

It’s important not to skim through this part, so let’s break down how to properly measure your yard for a trampoline: 

How to Measure for a Trampoline 

Step #1: First, find the spot in your yard where you want to place the trampoline. We recommend that you find an area that is clear of branches, debris, fences and slopes. Here are some further recommendations for finding a spot: 

  • Find a spot that is flat and even (if the space you have isn’t level, we recommend the rise/gradient be no more than three degrees across the whole space.  We don’t advise installing a trampoline where the slope is greater than that).  

  • Safe lateral clearance space of 3-5 ft on all sides of the trampoline.  

Step #2: Next, grab your measuring tape and measure the length and width of the area you want to place the trampoline. 

Step #3: Once you have the measurement, add 3-5 ft more to all sides to the overall size so you have enough clearance space to safely put the trampoline in the desired area. (We recommend that every vertically standing obstacle, like a fence, shed or tree, have 3-5 ft of clearance space.  

Here are some important things to keep in mind when measuring your yard for a trampoline: 

  • Not all trampolines are the same when it comes to space: A traditional trampoline with static metal poles and a non-flexible net will need less clearance space than a trampoline with a flexible net and enclosure roles, like a Springfree Trampoline. Make sure to consider the design of the trampoline when measuring. 

  • How much clearance space you should accommodate for the trampoline is based on your trampoline manufacturer’s recommendations for clearance space. Check with your manufacturer to see the additional space you should take into account when measuring for the trampoline. 

  • The space you need can also depend on who’s jumping. If your kid is an aspiring gymnast that does consistently practices flips and tricks on the trampoline, you might want to make more room than a kid that uses the trampoline to play basketball. 

  • At the end of the day, it is your decision on how much space you want to make for the trampoline: If you’re comfortable with the amount of space you’ve allocated for the trampoline, then go with what you think is best. However, there is a risk of injury if proper clearance space is not accounted for. 

  • You will also want to consider which shape of trampoline fits best in your backyard. Some of the common trampoline shapes include round, square, rectangle and oval.  

Here’s a visual representation of what 5 ft of clearance space looks like on each side.

  1. Decide Who Will Be Using the Trampoline 

The next major step you need to take when deciding which trampoline size to buy is assessing who will be regularly jumping on the trampoline. 

Particularly, you need to pay attention to what’s called the single jumper weight capacity, or single user weight. This is the metric set by manufacturers that lets you know the recommended maximum weight of a jumper so you can safely jump without bottoming out. It is calculated by taking the expected height the jumper will reach and their weight.  

For example, our Springfree Jumbo Square Trampoline has a single jumper weight capacity of 220 pounds. If you weighed 220 pounds and reached maximum height on the trampoline, you would not be at risk of “bottoming out” or falling through the trampoline.  

However, if you weigh over 220 pounds, you have an increased risk of bottoming out. It doesn’t mean you can’t jump on the trampoline if you weigh over the weight capacity; it just means there is a risk of bottoming out if you reach maximum height. 

***What to do: Figure out the weight of all potential jumpers and find a trampoline that will be able to safely accommodate the jumpers’ weight. The weight capacities of trampolines should be available online through the manufacturer’s website or you can contact the company you want to purchase from if you have questions.  

If you’re buying a trampoline for your child, you also need to think about your child’s potential growth as they get older. 

If you have a nine-year-old and want them to have a trampoline to jump on for the rest of their childhood, then you’re probably not going to want to buy an 8 ft trampoline: They will likely grow out of it in a few years. 

That’s why it’s worth it to go ahead and purchase a bigger trampoline (assuming you have the requisite space) if you plan to keep the trampoline for the long haul. It will ensure that you don’t have to buy another trampoline down the road when your child needs more jumping space. 

Think of trampolines like clothes: It’s better to buy something your child can grow into than grow out of in a short period! 

  1. Consider All Other Factors 

The first two steps will give you the technical information you need to find the right-sized trampoline. Now it’s time to tie in all the other factors. 

After finding the size of trampoline you need, ask yourself these questions to lead you to your ideal trampoline: 

  • What type of trampoline do you want—spring or springless? Above ground or inground

  • How safe is the trampoline?  

  • Is the trampoline made from quality material that will ensure its longevity throughout childhood? 

  • Can this trampoline withstand years of jumping and weather conditions without breaking down?  

  • How’s the design of the trampoline? Would it look good in your backyard? 

  • Does the trampoline have good user reviews? 

  • Finally, what’s the cost of the trampoline? Is it within your budget? 

Other factors to consider: Warranty, installation, customer service and trampoline accessories.
