How to Calculate Vee & Wedge Belt Length
How to Determine which Fan Belt you require
If the centre distance (C) is known, belt length or pitch length can be determined as follows:
So if you know the distance between the center points of the pulleys, and their diameters, you can calculate the length of belt you need using this formula.

Step 1
Please enter distance between the centres of the pulleys and the diameters of both the pulleys, or if you know the length of the belt you require, simply enter the length below:
Types of Belt
A / B / C / Z Section Belts: These type of belts are known as classical vee belts. If the section is suffixed with an 'X', this indicates that the belt is cogged to allow fitting at tighter angles.
SPA/SPB/SPC/SPZ Section Belts: SP denotes that the belt is a wedge belt. Again, an 'X' suffix indicates a cogged fitting.
