Trampolines provide fun and exercise for both kids and adults, and weight limits will help keep everyone on a trampoline as safe as possible.

But what determines the weight limit on a trampoline? The size and shape of a trampoline as well as the materials involved have an impact on how much weight a trampoline can handle, and each trampoline will have different guidelines.

Read on, as I will be talking you through the rather mysterious concept of a trampoline’s weight limit.

A Backyard Trampoline’s Weight Limit Explained

Before we continue, let me emphasize that you should always check the manufacturer’s product recommendation for the exact weight limit specifications for your backyard trampoline model.

Why Are Trampoline Weight Limits Important?

Some might think that a weight limit for a trampoline is important to prevent the mat from bursting.

While there is truth in that thought, the other important reason to have a weight limit on a trampoline is to avoid the mat touching the ground or surface when jumping, which obviously can be quite dangerous.

If a trampoline’s weight limit is set at 500 pounds, for instance, then that guideline tells you that it’s safe for the combined weight of all jumpers, or anything on the trampoline, to reach 500 pounds.

Note that there can be two types of trampoline weight limits:

  1. Weight limit per person
  2. Total weight limit

The weight limit per person simply refers to the max weight limit per person. If that limit is set at 250 pounds, then no one jumper should be heavier than 250 pounds.

The total weight limit is the max weight the trampoline can handle at one time.

Weight Limit Testing

The American Society for Testing and Materials (ASTM) requires that a trampoline should be able to withstand up to four times the weight limit.

In other words, if a trampoline’s weight limit is set at 200 pounds, then that trampoline needs to be able to hold a weight of 800 pounds during testing.

Please do note though that not all trampoline manufacturers are required to pass these ASTM trampoline tests, so don’t expect all backyard trampolines to be able to hold four times the recommended weight limit, and definitely don’t try and test that at home.

One of the better known trampoline manufacturers however, Skywalker, does run its trampolines through ASTM tests, to make sure they meet the highest safety standards.

Factors that Determine a Trampoline’s Weight Limit

There are a few factors that come into play when determining a backyard trampoline’s weight limit:

  1. The springs
  2. The frame
  3. The mat
  4. The shape
  5. The size

Let’s discuss these factors in a bit more detail.

1. The Springs

This may come as a surprise, but the springs of a trampoline handle the majority of the weight when someone is jumping. It’s not the mat, it’s not the frame, it’s the springs.

Trampoline springs

Most springs are made of steel, which makes them stronger and are able to hold more weight. Some steel springs are also galvanized, which further improves the weight capacity.

Also note that the springs are not only the most crucial part of a trampoline, they are also the most vulnerable, so it’s important to regularly check them for any damage and rust.

2. The frame

Similar to the springs, the frame of a trampoline is typically made of steel, to make sure the trampoline is as robust as possible. But a solid steel frame also helps with managing weight.

Frames, depending on their design, can certainly buckle when too much pressure is applied. It’s typically the legs of the frame that are the most vulnerable.

3. The Mat

Of course, the mat of the trampoline also plays a huge role when it comes to handling weight. Or rather, the materials that the mat is made of.

A trampoline mat consists of woven fabric, and as such, there’s only so much a trampoline mat can handle when pressure (from jumping or any weight) is applied.

Trampoline mat

The more weight on the mat, the more it will bend towards the ground, and the more chance that tears will start to pop up. This is why it’s important to set a weight limit, to avoid too much bending and to avoid tearing up.

4. The Shape

The shape of the trampoline is also a factor, although most backyard trampolines are round-shaped these days.

Though circular trampolines allow for perfectly even weight distribution, rectangular trampolines usually have higher weight limits. Most round trampolines top out at about 350 pounds, and rectangular trampolines typically handle up to 500 pounds unless they’re unusually small.

Those numbers can of course change if the trampolines are much smaller or larger than your typical backyard models.

Check out my guide to trampoline shapes for an outline of the different types of backyard trampolines available.

5. The Size

The size is also a factor, with larger trampolines typically allowing for higher weight limits than smaller ones.

Some smaller trampolines designed for toddlers can have weight limits of less than 100 pounds. There are also smaller adult trampolines that are used for exercise, known as re-bounders, and these exercise trampolines can have surprisingly large weight limits of up to 300-400 pounds.

Here are some average user weight limit numbers for backyard trampolines:

  • 13 feet: 250-300 lbs
  • 15 feet: 300-350 lbs
  • 17 feet: 350-400 lbs

Final Thoughts

As I mentioned above, it’s always best to stick with the manufacturer’s instructions and guidelines when it comes to your trampoline’s weight limit.

Also note that the age of the trampoline and the amount of exposure it’s had to sun and extreme temperatures can have a negative impact on that weight limit and other safety aspects of your trampoline.

Common sense goes a long way, always respect your trampoline’s safety guidelines, and don’t try to push your trampoline to its limits.
