Trampoline Size Guide and Dimensions for All Ages and Weight

Trampolining dates all the way back to 1936. Trampolines are among the few devices you can use for backyard fun. A trampoline is a mechanism made from a metallic frame with springs or rods and a strong fabric on which you can bounce. People use them for recreation, in acrobatic and gymnastic competitions, or for exercise.

Before you select your jumping surface, you’ll want to consider several factors that determine the most suitable trampoline size for you. So, if you want to avoid the hassle of returning a trampoline after purchase, we’ll give you the information you need to make the best decision.

How do you pick the right size trampoline?

Trampolines come in common sizes that you can choose from. However, to choose the right size, you should think about the purpose of the trampoline. Are you buying a trampoline for your kids to play with or do you want to practice gymnastics routines? The ideal size trampoline should be large or small enough to accommodate the number of people who’ll be using it.

This means you should consider how many kids or people will be using the trampoline at the same time. Smaller trampoline sizes could allow for one child to jump at a time and won’t work well if you want several children to play together on the unit. If you plan to jump on the trampoline with your entire family, kids and adults alike, then larger trampolines are the way to go.

If you want a trampoline for your kids, you should also consider their growth process because they could outgrow the model you choose in a couple of years. As such, you should account for their future growth and development and get a trampoline you can use for years.

Something else to consider is the available backyard space. Mostly, the backyard is the best location to set up a trampoline. The amount of room you have available will determine the trampoline size you choose. For a compact backyard, you could be stuck with mini-size trampolines since larger-size trampolines won’t deliver a perfect fit. It’s essential to learn about standard trampoline sizes because you’ll need to determine the necessary clearance.

On the other hand, if you have a larger backyard, you could take a trampoline that makes the best use of your space. A medium-size backyard could accommodate a larger size trampoline than a small yard but it might not be the best choice for a full-size trampoline. Keep in mind you need a space of about 1.5 meters or 5ft around the trampoline if you will mount a safety enclosure net.

The size of trampolines also comes into play if you have a busy backyard. Will the trampoline leave enough lawn space for other activities? Will it make your outdoor space look cluttered or affect your overall landscape view? These questions can help you choose perfectly sized trampolines.

You should also evaluate how much money you are setting aside to acquire the trampoline. A small trampoline mat will probably be cheaper than the biggest trampoline. As such, you’ll need to compare the trampoline price with your budget to ensure you get a good size. Besides size, you’ll also need to choose whether you want a traditional or Springfree trampoline.

How to measure a trampoline

Trampolines come in different shapes and sizes. Some of the most common models include circular trampolines, rectangular trampolines, octagonal trampolines, oval trampolines, and square trampolines. The shape of the trampoline will determine how it’ll sit in your yard and who can use it.

Round trampolines are a popular choice because they are affordable and come in a wide range of sizes. They are a great choice for kids because they tend to keep the jumper in the middle of the jumping mat and have a relatively lower bounce height. Plus, since they don’t take up a lot of space, they are suitable for compact backyards.

The average trampoline sizes for round models are as follows:

  • 6 – 8 feet trampolines
  • 10 – 12 feet trampolines
  • 14 – 16 feet trampolines

Rectangular models have a higher price range and take a lot of space in the yard. They also don’t have a center-focused bounce making them great for multiple jumpers. A rectangular trampoline is better suited for exercise and practicing gymnastics since they offer maximum bounce.

Common rectangle trampolines come in the following sizes:

  • 4×6 ft trampolines
  • 7×10 ft trampolines
  • 8×14 ft trampolines
  • 9×15 ft trampolines
  • 10×17 ft trampolines

Oval trampolines are less common and they are more affordable than rectangular models but pricier than the round ones. They keep the jumper at the center and have a large surface area making them excellent for kids.

Height is another thing to keep in mind when choosing the correct trampoline size. If you are getting a trampoline for kids, you shouldn’t go for an Olympic-size trampoline since you want the kids to easily climb on and off it. This means you should consider the height of the trampoline in contrast to the user’s height to determine if it’s suitable.

What size trampoline is good for adults?

Trampolines aren’t just for kids. There are some ways adults can use a trampoline for fitness and exercise or other forms of athletic training. You don’t have to automatically go for the largest trampolines because you’re an adult. Even mini trampolines can be the perfect choice especially if you are looking for a creative way to exercise.

To ensure you can bounce well at any section on the jumping mat, go with a rectangle trampoline. It’s crucial to also consider the weight capacity of the trampoline model you want. Trampolines have different weight limits for individuals and groups and you’ll need to familiarize yourself with this information to reduce the chances of accidents.

The standard sizes of trampolines affect the weight limit because the trampoline frame is designed to bear a specified amount of weight. If there will be several individuals using the trampoline simultaneously, knowing the weight limit will help you keep your model from breaking down.

Finding the right trampoline size can be a hassle if you don’t know the right considerations to make. Fortunately, you’ve learned how to pick a trampoline size that will conveniently meet your needs. There are many advantages of getting the right size and type of trampoline.

Trampolines can enhance your family bonding experience, improve your gymnastics training sessions, and help you maintain a fit body. To ensure the safety of trampoline users, follow the safety instructions that come with your model. You’ll first need to decide on the shape you want and you can choose from an octagonal, rectangular, oval, or square trampoline.

Once you decide on the shape, you can look for a standard size from the charts and compare it with your backyard size. It’s crucial to maintain a clearance of about 8 feet around the trampoline for maximum safety. The age limit also comes into play because some trampolines are too large for small kids and others could be too small if several kids will jump at the same time.

You don’t have to go for a giant trampoline to ensure a fun session since smaller trampolines could pack all the power you need. Thanks for reading to the end. If you enjoyed the content or have questions, leave a comment below.
