Abstract: This disclosure describes providing techniques to measure caliper of the paper material. A system may include a first laser head that is disposed above a reference located along an edge of a roll to and a second laser head that is disposed above a top surface of paper material on a roll. The first laser head measures a first distance from the first laser head to the reference located along the edge of the roll. The second laser head measures a second distance from the second laser head to the top surface of the paper material. The system performs calculations for caliper, T, by subtracting the second distance from the first distance, to be the caliper of the paper material. The system also records and creates graphs of the caliper measurements.
