How do you measure a trampoline size is quite easy to do when you know the correct way to do it. Think of this as a sort of trampoline measuring guide.

You do not need to sit there scratching your head and saying ” How big is my trampoline “.
Quite simply put you measure a trampoline from one side to the other. This is from frame to frame. A lot of people will make the mistake of measuring just the mat, and this is incorrect.
Trampoline measurements are usually in feet. If you measured your trampoline to be just over 3 metres it would be classed as a 10ft trampoline.
Hopefully that clears it up a bit for you.
