Rock Sizing for Drainage Channels Catchments and Creeks

2.2 Rock type and grading Crushed rock is generally more stable than natural rounded stone. A 36% increase in rock size is recommended for rounded rock. The rock should be durable and resistant to weathering, and should be proportioned so that neither the breadth nor the thickness of a single rock is less than one-third its length.

Particle-size distribution Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
