How to Measure a Rubber Belt

#1 - Get a ruler, 2 pens, and the old belt.

 


#2 - Pull belt snug and measure length (don't stretch!)
Multiply length X 2 for inside circumference (IC).
Belt above would have an approx 9" IC.
Now, deduct 10% for stretching: 9 - .9 = 8.1" IC


#3 - Measure belt thickness in inches.
Above belt is approx 1/16" thick or .07"

So, belt above would be approx 8.1 X .07"
If your exact size isn't in our database
pick a belt which is reasonably close.
