The small-scale fluctuations in the height of a physical surface are measured as surface roughness. Contrast this with larger scale differences like shape and waviness, which are often a feature of the surface’s geometry.

The significance of surface texture has come to light recently in a variety of sectors. In fields as diverse as tribology, surface coatings, microfluidics, and biocompatibility, surface roughness plays a significant role in determining a workpiece’s ability to operate satisfactorily.

The measurement of surface roughness can be described using quantitative or qualitative techniques. Optical characteristics, such as a surface’s reflectivity or the strength of the machining grain, as well as using a thumbnail as a primitive touch sensor, are examples of qualitative approaches.
