If your old trampoline mat has a hole over 4-inches long, please do not use this instruction set. Instead, please measure your frame and springs. If the mat has a small hole, do not measure across it.
When collecting #1 and #2 measurements below be sure to follow the 'grain' of your fabric. To find the grain, look closely at the fabric to notice the yarn runs in two directions - from 12-o'clock to 6-o'clock and also from 9-o'clock to 3-o'clock.
Measure in both directions following the middle of the grain.
Measure with the grain even if the metal hardware along the edge of your mat is missing in line with the grain. If metal hardware is missing, add the appropriate distance to your measurement to account for the missing hardware.
Mat can be measured while assembled or while laying on a flat surface. If measured off the trampoline, pull the mat flat while measuring.
