Roll Diameter Calculations

Calculations involving Roll Diameter can get complicated. For our customers we have developed the Roll Diameter Calculator below. Fill in any three of the four values, and click the "Calculate" button. The missing value will be calculated for you. Since roll diameter is affected by how tight or loose a roll may be wound, these calculations should be used as estimates.

Note:Do not type units or fractions into the entry boxes. For example, enter 5.5 for inches, not 5.5" or 5.5 in. Also, enter 3.0 Mils as simply 3.0, not .003.
