The Length of a Belt calculator computes the length of a belt that goes around two pulleys Belt length around two pulleys. based on the pulley diameters (DD and Dd) and the distance between the axles (L).

INSTRUCTIONS:  Choose units and enter the following:

• (DD) This is the diameter of the first pulley
• (Dd) This is the diameter of the second pulley
• (L) This is the distance between the pulley axles.

Belt Length (BL): The calculator return the belt length (BL) in meters.  However, this can be automatically converted to other length units via the pull-down menu.

#### The Math

BL = (DD+Dd)•π/2 +(L•2)+ ( (DD-Dd)² / (L•4) )
where:

• BL is the belt length
• DD is the diameter of the first pulley.
• Dd is the diameter of the second pulley.
• L is the distance between the axles.
