## Belt Length Calculator by Dura-Belt

**Belt Length Calculator by Dura-Belt** is one of the best free online tool that you can use to calculate belt length. It has listed 4 different methods on its website that you can use. Based on the condition of the belt length, you can use the method that you want. If the belt is brand new and unstretched then you can proceed with the very first method listed on the website. Or, if you want to calculate the belt length according to two pulley system then you can do that there too.

There is no need to sign up or register in order to calculate length of the belt. You just land on the main homepage of this calculator and then you are done. Based on the state of the belt you have, you will need to choose the method accordingly. Since, we are calculating length of the belt in pulley system so go for the method 3. You need to enter all the parameters there that it asks and see the corresponding results.

So, if you have unused or new belts then you can go with the direct method and the pulley system method. But if the belt is stretched then you will have to go for other methods on the website. There are diagrams corresponding to different methods are drawn and you can take help from them if you want to.

## Belt Length Calculator by Bbman

**Belt Length Calculator by Bbman** is a very good tool to calculate belt length. This is like any other website that I have mentioned in this list. Here this is kind of advanced tool to calculate belt length as here it lets you consider number if teeths in the belt as well. You can define type and size of the teeths in the belt and then specify other parameters and get the results. Simple as that. It offers you a nice interface where you just enter the details about the belt and get the results in real-time.

Use the mentioned link to reach the homepage of the calculator and then you can simply start entering the details. Start by specifying style and number of teeth. It supports teeth types of MXL, XL, L, and H. You can select the one from the main interface and then proceed by specifying the details about pulleys. In the end, enter the distance between the centers and then it will give you the result on the right side.
