The measurement of paper thickness is accomplished using a paper caliper. This specialized tool is designed to provide an accurate reading of how thick a particular sheet of paper is, which is essential in various industries, especially in printing and publishing. The precision of a paper caliper allows manufacturers and designers to ensure that the correct paper weight is being used for specific applications, as thickness can significantly affect print quality, texture, and overall aesthetics.

Other devices listed, such as resolution gauges and pixel meters, are not intended for measuring physical dimensions like thickness; they are used for assessing quality aspects related to image resolution and pixel density, respectively. The chromaticity tester, meanwhile, focuses on color measurement rather than physical properties like thickness. Therefore, the paper caliper stands out as the appropriate choice for accurately measuring paper thickness.
