How to Find the Length of a Roll of Paper
- 1). Weigh the roll of paper on a scale. Write down the weight of the roll in pounds.
- 2). Find the basic size of the paper. This is usually on the label (such as 17x22or 16x20).
- 3). Find for the weight (or thickness) of the paper. All paper has a specific weight. This is not how much the paper weighs but is a way to describe the thickness of the paper. Again the paper weight will be on the label.
- 4). Measure the width of the paper.
- 5). Set up this equation:
(Roll weight x (Basic Paper size)) x 500/ (Paper Weight x Roll Width) x12 = Linear Feet
If your roll weight was 60 pounds, the basic paper size was 20x26, the paper weight was 50 and the roll width was 10, the equation would look like this:
(60 x (20 x 26)) x 500 / (50 x 10) x 12 = 2600 Linear Feet
