To find the approximate linear footage in a roll of paper, multiply the weight of the roll by the square inches of basic size by 500. Divide by the sum representing the width of the roll, multiplied by the substance or basis weight, times 12.

Online Calculation  Roll Weight:  Basic Size (Height X Width):   X   Basis Weight:  Roll Width:  Linear Footage: linear feet

Formula Roll Weight x Area of Basic Size x 500 Basis Weight x Roll Width x 12   =   Approximate Linear Footage

Example Find the footage of a roll of basis 50lb. Offset paper, 26" wide and weighing 100lbs. 100 x (25x38) x 500 (50x26) x 12   =   3,044.87 linear feet
