How Do I Measure My Trampoline for Replacement Parts?

If you don’t know or can’t remember the size of your trampoline, you need to measure it before buying any replacement parts. Measuring your trampoline will help you choose the right replacement jumping mat, safety net or springs. Here’s how:

Measuring Your Trampoline

Measuring Round Trampolines

Round trampolines are measured by the overall diameter of the frame, not the jumping mat. If your trampoline has a safety enclosure, it may be easier to measure the trampoline frame from the floor or from under the jumping mat.

To find the diameter of a round trampoline:

  1. Stand in front of the trampoline entrance.
  2. Measure straight from the outer edge of the trampoline frame to the side directly opposite it (see image).
  3. Move to the left side of the trampoline. Measure the diameter again, but this time perpendicular to the first measurement (see image).
  4. Get the average of the two measurements by adding them up and dividing by two. This is the approximate size of your round trampoline.

Converting metres to feet:

  • 37m - 4.5ft
  • 83m - 6ft
  • 43m - 8ft
  • 04m - 10ft
  • 65m - 12ft
  • 26m - 14ft
  • 87m - 16ft

Measuring Rectangular Trampolines

Rectangle trampolines are measured by the length and width of the frame, not the jumping mat.

To measure a rectangle trampoline:

  1. Measure the short side of the trampoline frame (see image).
  2. Measure the long side of the trampoline frame (see image).
  3. Take both measurements. This is the approximate size of your rectangle trampoline.

Kahuna rectangle trampolines are available in two sizes: 6ft x 9ft and 8ft x 11ft. If you need replacement parts for your rectangle trampoline, you can find them below:

Converting metres to feet:

  • 83m - 6ft
  • 43m - 8ft
  • 74m - 9ft
  • 35m - 11ft

Measuring Oval Trampolines

Oval trampolines are measured by the length and width of the frame, not the jumping mat.

To measure an oval trampoline:

  1. Stand in front of the trampoline entrance.
  2. Measure straight from the outer edge of the trampoline frame to the side directly opposite it. (see image)
  3. Move to the left side of the trampoline and measure the longer side of the frame. (see image).
  1. Take both measurements. This is the approximate size of your oval trampoline.

At Kahuna we only sell one oval trampoline measuring 8ft x 14ft. If you need replacement parts for your Kahuna oval trampoline, you can find them below:

Converting metres to feet:

  • 83m - 8ft
  • 27m - 14ft

How to Choose the Right Trampoline Jumping Mat

Jumping mat sizes are based on the overall size of the trampoline they fit, not the mat’s actual diameter. If you know your trampoline’s size (or you measured it according to the instructions above), all you have to do is choose the same size when buying a replacement jump mat.

For example, if you have an 8ft round trampoline, you should choose an 8ft jumping mat (the mat itself will be smaller than 8ft).

Check out the graphic below for more information:

Have an oval or rectangular trampoline? Simply choose the mat that corresponds to your trampoline’s size. For example, if you have an 8ft x 11ft rectangle trampoline, you should also buy an 8ft x 11ft jumping mat.

How to Choose the Right Trampoline Safety Enclosure / Net

Here at Kahuna we sell three types of trampoline enclosures:

  • Inner (for Classic Round and Pro models),
  • Outer (for Twister models), and
  • Outer (for Blizzard models).

If you are not sure which Kahuna model you have, you can refer to the user manual or send us pictures of your trampoline and we will identify it for you. You can also check the graphic below to help you identify your trampoline:

Kahuna Classic, Kahuna Twister and Kahuna Blizzard

Just like jumping mats, net sizes are based on the overall size of the trampoline they fit. This means that if you have an 8ft trampoline, you should buy an 8ft safety enclosure (regardless of whether it’s an inner or outer model).

The only exception would be our Outer - Blizzard trampoline nets, which come in a wider variety to suit other brands. This net is fitted onto your trampoline by inserting it over the poles, so aside from checking the size, you should also make sure that the number of poles on your trampoline matches the number of holes on the netting.

How to Choose the Right Trampoline Safety Pad / Spring Cover

Choosing a replacement spring cover is fairly straightforward. Just select the size that matches your trampoline’s overall diameter and it should fit correctly.

How to Choose the Right Trampoline Springs

Different trampolines require different size springs to maintain their safety and bounce. Check the table below for more information on choosing the right springs.
