Roll Weight
Roll weight is the approximate weight (in pounds) of a roll of paper. Use this calculator to easily measure roll weight by providing the roll diameter, core diameter, roll width, and appropriate factor for a given type of paper (see the example below). When filling in these fields, use decimal fractions where necessary; and give all lengths in inches.

Example
Find the weight for a roll of forms bond paper with a roll diameter of 40 inches, a core diameter of 3 inches, and a width of 17.5 inches.
Formula:
| ([Roll Diameter2 - Core Diameter2] × Roll Width) × Factor | = | Roll Weight |
Equation:
| ([402 - (32] × 17.5) × .021 | = | 585 (rounded to nearest pound) |
