Can this calculator handle belts with different pitch lengths?

The tool includes pitch options such as 5 mm and 3 mm, and displays requested and nearby belt teeth for common pitch configurations, but it is optimized for standard two-pulley sizing rather than custom pitch matching.

Does the calculator provide belt length in both inches and millimeters?

Yes, the interface includes unit selection for inch and metric, and the center distance and pulley diameter inputs accept both units, allowing the result to be displayed in the chosen unit.

What information is shown about the next larger or smaller belt?

The calculator lists the next larger and next smaller belt options with their tooth count and center distance, helping users find a belt that fits their existing pulley setup without major adjustments.

Is the Belt Length Calculator free to use without registration?

The calculator is publicly accessible on Plummer Industries and is free to use online without requiring a login or subscription.
