Of these properties, grain size is arguably the most important. It can help a geologist interpret the geomorphic setting (both present and historical) of a site, as well as whether the sediment was transported there from regional or local settings. Grain size determines just how far a piece of sediment can travel before coming to a halt.

Grain size has an effect on the fracture toughness of ferroelectric ceramics. Optical microscopic observation of Vicker's indents on PLZT 9/65/35 ceramics with different grain sizes indicates that the crack size becomes shorter as the grain size decreases, while the pyramid diagonal remains the same with respect to the grain size changing (Uchino, 1997).
