How to Measure

How do I measure the size of my trampoline?


For Round Trampolines:

The size of a round trampoline is measured by the diameter of the metal frame (not the jumping mat).

  • To find the diameter of your round trampoline, start at the outer metal edge of the trampoline.
  • Measure straight across to the opposite side, to the outer metal edge of the trampoline.
  • Then measure the frame diameter again, but measure perpendicular to where you just measured.
  • Take the average of the 2 measurements, and that should be your approximate trampoline size.
  • Measuring twice this way will help ensure that you get an accurate measurement in case the frame is bent or damaged, or the trampoline is not sitting on level ground.


Important: Frame should only be measured if all the springs are properly attached and the jumping surface is correctly installed. 

Note: Our round trampolines only come in10 foot, 12 foot, 14 foot, 16 foot diameters, and the 10ft and the 12ft have 4 U legs and the 14ft has 5 U leg and the 16ft has 6 U legs. If your trampoline is a different size, or has legs that are not the same quantity as described, then your trampoline is not a Super Jumper Inc. trampoline.

How do I check to see if if my trampoline is compatible with a Super Jumper Safety Net??


  • Two trampolines have 4 "U"- or "W"-shaped legs, which means there are 8 vertical leg pieces connected to the trampoline rails, 2 per "W". Some trampolines however, have more "W"-shaped legs, and some have less. Super Jumper's Safety Enclosures have 8 poles, and on round trampolines, will work with either 4 or 6 leg W/U-shaped leg configurations. Standard installation instructions for a 4 leg trampoline are included in the box. For a 6 leg trampoline, see our 6 leg configuration document. For other leg configurations, please call Super Jumper Customer Service at 650-692-6188.
  • Super Jumper Brand enclosures will only fit Super Jumper Brand round trampolines.
