Footage on Roll

How to use it

1. Measure the outside diameter (OD) of the roll in inches.
2. Enter the outside diameter of the core in inches.
3. Enter the thickness of one wrap in mil.
4. The remaining footage appears in feet and metres.

Example

A roll with a 10″ OD on a 3.5″ core, wound with 2 mil sheeting: about 2,870 ft left on the roll.

Good to know

• For lay-flat tubing, one wrap is two layers, so enter double the gauge.
• Measure the OD across the full roll, not just the outer edge of the film.
• Tightly wound rolls match the result closely; loosely wound rolls hold a little less than calculated.
