ROLL LENGTH CALCULATOR
Use this conveyor belt roll length calculator to check how much belt is left on a roll without unrolling it. Enter the outside diameter of the roll, the core diameter and the belt thickness.
Belt length from roll diameter
Measure the outside diameter of the roll and the core, enter the belt thickness, and see the approximate length of belt on the roll.
Don't know the thickness? Estimate it
About 1.2 mm per ply is a common figure for EP fabric; check the belt data sheet for the exact value.
L = π × (D² − d²) ÷ (4 × t). The real length can differ by a few percent with winding tightness - measure before cutting.
