    A cobble is a clast of rock with a particle size of ~2.5 to 10 inches or 6-25 cm, based on the Krumbein phi scale of sedimentology. Cobbles are generally considered to be larger than pebbles (4 to 64 millimetres diameter) and smaller than boulders (greater than 256 millimetres diameter, or generally, 30 cm/1 foot [1 meter is 3 feet]).

Clasts larger than cobbles are classified as boulders. Clastic sedimentary rocks can also be identified by the characteristic of clast sorting. If most of a rock's clasts fall within only one or two of the particle size classes above, the grains of the rock are said to be well sorted.
