How does sand form? - National Ocean Service

Sand is measured according to specific parameters. If more than 50 percent of the material is larger in diameter than 75 microns (.03 inches) but smaller than .18 inches, it is said to be sand. If the average particle size is smaller, it is considered to be silt or clay, and if the average particle size is larger, it is garden-variety gravel.
