Hey PaPaMuski,

Thanks for your question and welcome to the community. 

Your question is way too vague and broad for anyone to give you a specific answer without getting more information from you.

For example:

  • What is the size of the pulleys?
  • What is the pulleys being used for? Using the right grade and type of belt is important for a specific job.

Let us know in more detail what you need, and in turn, we can assist you further.

Hello PaPaMuski.

If you have some string or rope, wrap it around the pulleys and mark the spots where they meet.  Uncoil it and measure how long it is.

You can also make an approximation of the proper belt size with a little measurement and a little math.

The inside width of the pulley, (where the belt goes), will determine the belt width.

As far as length goes, see the illustration below:
