Feb 24,  · Hi, My name is Alisa. Today we are going to look at how to measure a v-belt so that you can get the proper replacement. The two measurements that you need at the top width and the outside measurement.
The length of a men’s belt is measured from the end of the turn-back (the fold through which the buckle bar passes), to the centre belt hole. Shown below is a 32 inch belt, and you can see clearly how this length measurement has been derived.
