…Granular materials generally have irregular shapes and are composed of particles of random sizes. To express the particle size of irregularly shaped particles, the three-axis mean diameter, the circle equivalent diameter (Heywood diameter), the unidirectional diameter (Feret diameter), the area equivalent diameter (Martin diameter), and the Stokes diameter are used. The three-axis mean diameter is the arithmetic average of the length, width, and thickness of the particle. … *Some of the terminology that refers to "equivalent circle diameter" is listed below.
