      2019-11-27 · Particle Size Measurement. Only in the case of a single sphere can the size of a particle be completely described by one number – its diameter. For other regular shapes it is usually necessary to specify more than one dimension; a cuboid is defined by length, width and height. For the vast majority of materials, particles are rarely spherical.
