Top 5 Facts Everyone Should Know About Trampoline Weight Limits
Have you found yourself searching through trampoline brands trying to find the one that will give you the best weight limit? We get it.
After adding up the weight of your children, factoring in growth over time, and knowing the kids will certainly beg for you to jump with them, the weight limit of your trampoline seems like it should be triple what most say.
Rest assured, a weight limit doesn’t need to scare you away. Here are five facts everyone should know about trampoline weight limits.
1. A weight limit is the amount of weight your trampoline can normally bear
A weight limit is the amount of recommended weight a trampoline can bear during normal use. For example, if you have a trampoline with a weight limit of 200 lbs., you’re probably not going to want to let your 3,000 lb. pet hippo test it out. Just trust us on this one. Below is our weight limit chart on our trampolines.
Rest assured, just because your pet hippo can’t jump doesn’t mean your Aunt Bertha shouldn’t.
2. We calculate weight limits using ASTM standards
This is where things get interesting. We determine our weight limits based on ASTM standards. To be compliant, the trampoline needs to successfully withstand four times the specified user weight. This being said, a trampoline weight limit of 200 lbs has been tested successfully at 800 lbs.
Keep in mind that ASTM compliant weight limits are completely optional for trampoline brands to follow.
3. ASTM standards use a static load test to determine
A static load test process includes slowly lowering a loading disk onto the surface of the jump mat for five minutes. The trampoline is inspected for signs of deformation and breakage on the frame, jump mat and springs.
Pro-Tip: Check for ASTM standards before purchasing a trampoline.
4. The shape of your trampoline affect the weight limit
A rectangular trampoline will typically be able to hold more weight than a round trampoline. This is because the springs on a rectangular trampoline work independently.
The springs on a round trampoline work together. They use the strength of all the springs during each bounce, no matter where you jump on the mat.
5. The materials of the trampoline affect the weight limit
The three most important trampoline materials that affect the weight limit include:
- Jump Pad
- Enclosure Net
A jump pad made of high-quality polypropylene will increase the weight limit. As for the springs and frame, a rust-resistant galvanized steel will be your best bet. The length of the springs also play into the weight limit (and the overall bounce).
