Here are instructions on how to measure for a round replacement trampoline mat. If you are confused please call us at 800-753-5378 and we will be happy to walk you through this over the phone.
Step 1; Take 4 individual measurements from a spring hole on one side of the trampoline frame to the spring hole on the opposite side of the trampoline frame. (This works best if you have two people measuring). You will be measuring straight across the frame. Once you take your first measurement simply count 5 springs holes to your right and your helper will count 5 spring holes to their right and then you will have your 2nd measurement, continue until you have a total of 4 measurements. Please note measurements in inches.
Step 2; Count the total spring holes in your trampoline frame. Some frames will have 88, 96, 100, 104 etc.
Step 3; Measure the length of 2 or 3 trampoline springs. These need to be measured in a relaxed state, not stretched out in any way, while off the trampoline frame. Be sure to include the hook at each end of the spring when you measure. Some springs will measure 7 inches or 8.5 inches.
