It is very important when measuring your trampoline that you do this correctly.
A lot of people can make the mistake when measuring the trampoline that they measure the trampoline mat, this is incorrect.
What will then happen if you do this people go and purchase parts for their trampoline only to then find out they have purchased the wrong size.
The correct way to measure your trampoline is from frame to frame, so you actually measure it from one side to the other.
As an example if your measurement was just over 3 m you would have a 10 foot trampoline.
So that is how you measure the trampoline.
