To measure a rebounder, you need to determine its diameter, which is done by measuring the metal frame from edge to edge.
Understanding the size of your rebounder is crucial for purchasing replacement parts like jump mats or safety pads. The standard way to measure a rebounder or trampoline is not by the jumping surface itself, but by the overall size of the frame.
The Correct Way to Measure
According to standard practice, including the information provided: The Trampoline diameter is measured from the outside of the metal frame to the outside of the metal frame (not the jumping surface).
Here's a simple step-by-step guide:
- Gather Your Tool: You will need a standard measuring tape.
- Ensure Assembly: Measure the rebounder with the mat still fully assembled.
- Locate Measurement Points: Place the end of your measuring tape on the outside edge of the metal frame. Extend the tape straight across the rebounder to the opposite outside edge of the metal frame.
- Take Two Measurements: Because frames can sometimes be slightly out of round, measure the diameter in 2 spots. Ideally, these measurements should be perpendicular to each other (forming a cross shape across the rebounder).
- Calculate the Average: Uses the "average" of these two measurements as your "actual" Trampoline size. To find the average, add the two measurements together and divide by two.
For example, if your first measurement is 38 inches and your second measurement is 39 inches:
(38 inches + 39 inches) / 2 = 77 inches / 2 = 38.5 inches.
Your rebounder size would be 38.5 inches.
This method ensures you get an accurate measurement of the total frame size, which is what manufacturers use to size replacement parts.
Why Frame-to-Frame?
Measuring from the outside of the frame provides the overall footprint of the rebounder. This measurement is critical because replacement parts, especially jump mats and spring pads, are designed to fit the specific diameter of the frame, taking into account the number and size of the springs. Measuring only the jumping surface would give an inaccurate size relative to the components designed to fit the frame.
By following this simple process, you can confidently determine the size of your rebounder for maintenance or replacement purposes.
