Method A:

If you have your old mat and it has no holes longer than four inches:

• When collecting #1 and #2 measurements below be sure to follow the 'grain' of your fabric. Looking closely at the fabric you will 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.

Method B:

If you don't have your old mat or it has no holes longer than four inches:

• Collecting these measurements requires two people.
• Hold the measuring tape tight. Do not let the tape sag.
