Trampoline Size Guide (What Trampoline Size is Best?)

Use our size guide to find the perfect fit for your family and backyard. We cover the key factors to consider, available sizes, and how much space you’ll need for your new trampoline.

If you’re thinking about getting a new trampoline, but you’re not sure what size is best, then this article is for you.

We’ll cover essential information about trampoline measurements, available sizes, and the factors to consider when selecting the perfect trampoline for your family.

Before we get into the article, if you’re just looking for a list of the common trampoline sizes in Australia, we recommend this guide from Vuly.

Ok, let’s kick off by quickly covering how a trampoline is measured.

How is a trampoline measured?

To measure the size of a trampoline, the frame is measured from one side to the other (the diameter).

To measure your own trampoline at home, use a tape measure and measure across the centre of the trampoline.

You may want to do this a few times in different directions to ensure you’re getting the same measurement. Remember that the trampoline size includes both the jumping surface and the springs/safety mats.

Here’s a video that walks you through the process:

Trampoline sizes in Australia

Size is one of the first considerations when buying a trampoline. You need to make sure that the trampoline is large enough for all of your family members to enjoy, but also that it won’t take up too much space in your backyard.

Here are the basic sizes:

  • Small: 2.7m (8ft)
  • Medium: 3.2m (10ft)
  • Large: 3.8m (12ft)
  • Extra Large: 4.3m (14ft)

These sizes are based on Vuly trampoline sizing but are fairly standard across the market.

If you have plenty of space (and the budget for it), then go big! A larger trampoline can accommodate more people at once and has more room for them to jump around without fear of bumping into each other.


Whichever trampoline you choose, we highly recommend also purchasing an anchor kit, which will secure your trampoline to the ground.

Trampoline 4 | Trampolines

Trampoline brand Springfree recommends that people aim for a clearance space of 1.5m on all sides of the trampoline.

Therefore, for a round, 10 foot (3 metre) trampoline, you’d want a space that is 6m long and 6m wide.

It’s best to place trampolines away from any obstacles that could cause injury, such as buildings or fences.

What size trampoline should you buy?

There are no hard rules in terms of trampoline sizes and ages.

However, if your kids want to learn and practice tricks or if more than one wants to jump at the same time, they will likely benefit from the extra space provided by a larger trampoline, such as a 12ft or 14ft.

The problem with bigger trampolines is not only are they more expensive, but they also take up a lot more space.

Australian trampoline brand Vuly says that “families with one or two slightly older children (6-10) may find that our Medium-sized (10 ft) trampolines… more suitable”.

They say that this size provides enough space for users of all skill levels and can be used by both children and adults.

Vuly also comments that this size is just right for the average Australian backyard.

Here’s a summary of what New Zealand trampoline brand JumpFlex says about their trampoline sizes:

  • 10 ft trampoline – Ideal for smaller yards, 3.1m of space required, fits 1 adult or 2 young kids
  • 12 ft trampoline – Most popular size, suitable for all ages, 3.7m of space required, fits 2 adults or 3 young kids
  • 14 ft trampoline – Great for large lawns, space to learn tricks, 4.2m of space required, fits 3 adults or 4 young kids

What is the standard size trampoline?

10ft trampolines are considered small/medium and 12ft trampolines are considered medium/large. These are some of the most common sizes of trampolines.

These sizes would suit most families without taking up too much space in your backyard.

Springless vs Spring Trampolines

It’s important to note that on springless trampolines, the jumping surface is often larger than on traditional trampolines.

This is because the springs and frame are located beneath the jumping mat.

Instead of regular springs, springless trampolines use one of the following:

  • heavy-duty elastic straps
  • flexible composite rods
  • leaf springs

Because there are no springs for children to put their hands in, or land on, they are generally considered to be safer than spring-powered models.

What is the biggest trampoline in Australia?

The biggest trampolines available for domestic use are generally around 16ft (4.9m) in diameter.

16ft trampolines in Australia include the Everfit Big Rebounder.

This affordable trampoline features a rust-resistant galvanised steel frame and 150kg weight limit.

Trampoline weight limits

trampoline | Trampolines

All trampolines should come with maximum weight specifications, so it’s important to read the manufacturer’s recommendations when you’re shopping for a new model.

These usually range from 100kg to 250kg.

In general, the recommended weight limit for a smaller trampoline will be lower than for a larger one.

Think about how many people you expect to use the trampoline at once and how many years you plan to use it for.

This is particularly important if adults will be using the trampoline as well as children.

Round vs rectangular trampolines

There are two main shapes to choose from: round and rectangular.

Round trampolines are the most common, as they’re usually cheaper and they direct the jumper back toward the centre of the trampoline.

This is generally considered to make them safer, although this design can also result in collisions between multiple jumpers.

Rectangular trampolines provide a higher bounce because multiple sweet spots on the surface area will provide the maximum bounce.

How much does a trampoline cost?

Trampoline 1 | Trampolines

In Australia, most trampolines cost between $400 and $1000.

There are, however, cheaper trampolines in the $100-$400 range that often have fewer safety features or are built with less premium materials.

High-end trampolines will cost you $1500+. Trampolines in this category include the Springfree trampolines which use flexible composite fibreglass rods instead of springs and the Vuly Thunder Pro which uses next-generation leaf springs.
