Soils usually contain inorganic material of three sizes: sand, which ranges in diameter from 0.2 to 2 millimetres; silt, between 0.02 and 0.002 millimetres in diameter; and clay, which is less than 0.002 millimetres. Most soils have some of each. Soils with a large proportion of each component are called loams.
