Calculated result

Approximate web length173.93 m
Label pitch103 mm
Whole labels before waste1,688
Whole labels after waste1,654
L = π × (203.000² − 76.000²) ÷ (4 × 0.160) L = 173931.33 mm Pitch = 103.00 mm; whole labels = 1688; usable = floor(1688 × 0.980) = 1654
Geometric estimate only: compression, liner caliper variation, winding tension, adhesive and real roll construction change actual yield. Verify critical quantities against an actual supplier roll.

How to use this calculator

  1. Measure the outside diameter of the label roll and the outside diameter of its cardboard or plastic core.
  2. Enter the combined thickness of the label, adhesive and backing liner, using the supplier specification where available.
  3. Enter the label height in the feed direction, gap and waste allowance. Check the estimated usable label count.

Thickness includes the backing liner. A small thickness error can make a large difference to the estimated count.

Formula and method

The calculator normalizes every dimension to millimetres, applies L = π × (D² − d²) ÷ (4 × t), divides web length by label pitch, rounds down to whole labels, then applies waste and rounds down again.

Worked example

For a 203 mm roll, 76 mm core, 0.16 mm combined material-and-liner caliper, and 103 mm pitch, the estimate is 173.93 m of web, 1,688 whole labels before waste, and 1,654 after 2% waste.

How to interpret the result

Use the result for purchasing and rough planning, then reconcile it against a physically counted supplier roll of the same construction.

Limitations

This is an ideal geometric estimate, not a guaranteed roll count. Compression, adhesive, liner variation, winding tension, telescoping and actual roll build can shift yield. Caliper must include every wound layer.
