How To Measure A Trampoline

Measuring your trampoline is very important to maintain its well-being, and keep you jumping for years to come. Over time there may be some aspects of your trampoline that start to break down due to general use and exposure to the elements. With proper measuring techniques and knowing a bit about your trampoline, you can order new parts easily. Keeping your jumpers safe is the number one goal.

Trampolining is very fun and is a great source of exercise. We want to make this experience as safe as possible so if your trampoline does not have a safety net then this is how you will measure to get the right one. Trampolines come in multiple different shapes and sizes, using different support legs and different size springs. Knowing how to measure a trampoline, and knowledge about your specific trampoline is paramount when searching for a net or replacement parts.

Although trampolines are simple in nature they are far from it when it comes to design and construction. Due to their size and the fact that they must support the full weight of multiple people they are meticulously constructed to be safe and enjoyable. If you need any replacement parts for your trampoline then knowing the exact measurements of all the different parts is very important. This will help you order parts that may not be made by the same company that made your trampoline. Measurements are universal amongst all trampoline companies: whether you’re measuring the diameter, legs, springs or trampoline mat, if you do it correctly all the companies will be able to efficiently help you.

Getting the correct fit is crucial to everyone’s safety to ensure that everyone can enjoy themselves and avoid injury.

Different Shapes

There are 3 common trampoline shapes that you will find in the store, which you can see here. These are the most efficient and easy to take care of.

Round Trampolines

Round trampolines are the most popular. They provide the most predictable bounce when you’re on them and they can easily fit in any space. There are no sharp corners so they are safe for kids.

To measure the diameter of a round trampoline you must start from the outside edge of the trampoline frame. The measurements will include the length of the springs as well as the jumping surface.

Take one measurement of the diameter and then a second measurement that is perpendicular to the first one. The average of the two numbers will give you an exact figure for the frame diameter of the metal frame. This is the number used to classify all trampolines. 

Rectangular Trampolines

A rectangular trampoline is most commonly seen in gyms. This is what professionals and aspiring Olympic athletes use to train and compete on. To properly measure a rectangular trampoline there must be two different measurements taken. The first will be the length which is measured on the long side from the outer metal edge to the opposite side. The second will be the width which is the shorter distance. It still should be measured from the outside edge in order to get the exact frame diameter.

All measurements should include the safety pad.

Octagonal Trampolines

Octagonal trampolines or oval trampolines are gaining popularity. An octagonal or oval trampoline shape is better suited for more experienced jumpers as they provide a larger jumping surface than a round trampoline. To get the correct measurement of this trampoline frame it’s crucial to start from one of the corners – this will be at the trampoline’s widest point and is what all the companies use if you need trampoline parts.

Once you have taken the measurement from one corner straight across to the opposite one then do it again on a perpendicular line. By taking the average of the two numbers you can be sure of its accuracy. This will tell you if it is warped or possibly sitting on uneven ground.

Trampolines of this shape are always measured from one corner to the opposite corner.

Different Parts

There are several replacement trampoline parts you may need to consider.

Different Trampoline Parts

Net

This is a new and very useful addition; with the proper trampoline net, you can be sure that everyone jumping will be safe and will avoid injury. Not all trampoline nets are created equal though. They are made for different types and shapes of trampolines. This is why it is so important to measure your trampoline correctly.

If you get the wrong netting then there is a chance that it will not work properly: always be sure to confirm with your manufacturer about the proper size of netting needed to fit your trampoline perfectly.   

Springs

The proper trampoline springs will be included when you purchase your trampoline. There are a specific number of them so be sure to use the required amount. This will not only provide the most fun but will also keep everyone safe. In the event that you need to order new trampoline springs ensure you have the correct spring size – this is important to prevent any damage to your mat.

It’s recommended to keep an extra spring or two as a backup in case something happens to one. Rust is very common and can be harmful to not only your trampoline but jumpers as well. 

Pads / Spring Cover

In order to get the most out of your trampoline then having safety pads and spring covers are very important. These are used to protect the jumper from either hitting one of the netting posts or to keep them from getting pinched in the springs. These are custom-made based on the type of trampoline you have. If these did not come with your trampoline and you want to get some then having the proper measurements will be needed to get the right ones.

Frequently Asked Questions

To know the size of your trampoline you must first determine its shape to measure it accurately. For a round trampoline take two perpendicular measurements across the widest part starting at the edge of the metal frame. The average of these two numbers will be the size. For a rectangular trampoline simply measure the length and width from the outside edge and this will give you the frame size.

Yes, the size of a trampoline includes the springs. No matter the shape, trampoline sizes are always measured from the outside edge of the frame which includes the springs. This is to be able to fit the proper netting or to determine how many safety enclosure poles will be needed for the frame size.
