How To Measure A Trampoline Mats: 

The trampoline mat is one of the essential parts of the trampoline and it is being measured from frame to frame. You can’t measure the mat to mat distances because the mat stretches over time and that is why you must measure from frame to frame. Although you can get a quick measurement it will be slightly incorrect size if you measure the mat diameter. 

If you want a more precise measurement of your trampoline mat then you’ll need to consider taking a frame measurement. And the next part goes into the specifics of the procedure. Even so, it depends on the shape and type of the trampoline and the technique of measurement may differ slightly. Let’s have a look at the various methods of measuring trampoline mats according to their shapes.

Round Trampolines

The measurement of a round-shaped trampoline is quite simple in comparison to other shapes. You can perform this task of determining measurement in several ways for instance; 

  1. Firstly place your ruler or measuring tape on the frame of the trampoline
  2. Straight it across the frame and then measure the circumference from one end to the other.
  3. Perform this at least three times for determining the average value of the various angles. 
  4. After doing this, make a note of the data with an appropriate unit for the record.
  5. Now, you’ll need to take an average measurement of the trampoline mat’s diameter from fabric to fabric; however, do this while eliminating the V-rings of the springs. 
  6. You’ll also have to determine the measurement of the length of the springs and the number of V-rings or springs.
Round Trampolines

Square Trampolines

Usually, square trampolines have the same length and width and you do not need to put extra effort into measuring that. Now, let’s have a look at how you can determine the size of your square trampoline’s mat.

  1. Firstly, you’ll need to take an average measurement of your trampoline’s frame length and width from the outer sides. Because a square trampoline’s frame can be measured by determining the size of the trampoline from length and width.
  2. Then, measure the length and width size of the mat.
  3. After that, measure the length of the springs and the total number of springs.

 Rectangular Trampolines

If you have a rectangular trampoline and you want to replace the mat then the measuring procedure will be different. For this purpose, you’ll have to measure the length and the width of your rectangular trampoline’s mat. 

  1. Primarily, it is important to measure the trampoline frame’s length and width and then note down the measurements.
  2. Secondly, you’ll also need to measure the length or width of the rectangular mat.
  3. Finally, also determine the size of the springs in length and make a note of the number of springs.
 Rectangular Trampolines

Oval Trampolines

Oval trampolines are not the round ones but they seem round and you can measure them as you measure round trampolines. In conclusion, it requires a few additional measurements than the round trampolines. Let’s dive into the details!

  1. If you are willing to measure an oval trampoline’s mat than for you it is necessary to measure the longest side of the frame from the exterior side.
  2. After performing that part, now you’ll need to determine the smallest side space. 
  3. In the same manner, also measure the actual side of the mat.
  4. Eventually, measure the length of the trampoline springs and also ensure to count the number of them.

Complex Shapes

Measuring the frame and mat size of any type of trampoline such as hexagonal, octagonal, etc can be significantly more difficult than the other ordinary shapes of trampolines for instance round, square and oval, etc.  

  1. If you are required to measure the mat and frame of an octagonal or other complex-shaped trampoline then you must do so slightly.
  2. You’ll need to measure the frame length diagonally from one outer end to the other one. 
  3. In the same manner, also determine the size of the trampoline mat.
  4. At last, measure the length of the springs and then note down the quantity of the springs.

How To Measure Trampoline Springs:

The springs of the trampoline are the necessary parts of any trampoline because they help individuals to jump at height. When you are willing to replace the springs then this question arises: how to measure the trampoline springs? To get this answer just read further.

  1. Firstly, you’ll have to use a spring puller and then dismantle one or more springs from the end of the hook. 
  2. After that, use a ruler to determine the length.
  3. Then, determine the number of springs that you want to replace. 
  4. If you are willing to replace all the springs of your trampoline then disassemble them and count the total number of springs.

While measuring the spring’s length make sure that the spring shouldn’t be too strained. Do not include that spring into your measurement if that enlarges dramatically. The reason is that springs stretch to some extent over the period. Trace for the small extended one and do consider the stretching while you purchase the springs. You can also get the exact size by consulting the manufacturer of your trampoline.
