Wentworth grain size chart from United States Geological Survey Open-File Report 2006-1195: Note size typos; 33.1mm is 38.1 & .545mm is .594. Beach cobbles at Nash Point, South Wales. Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. Notice how the frac sand has a more uniform grain size, nicely rounded grain shapes, and a uniform composition. It is also a very tough material that can resist compressive forces of up to several tons per square inch. Grains in this image are about 0.50 millimeter in size.
