In terms of the shape of clasts the standard shapes are rod, sphere, disc and blade and these are derived from Zingg's (1935) classification. This classification system uses the measurements from the A, B and C axes with the cut off being 0.67 (see page 113 in the text by Gardiner V & Dackombe R 1983. Geomorphological Field Manual. If you send me an e-mail I can send you over the excel spread sheet I use. There is a more complex classification produced by Sneed & Folk 1958.

In terms of roundness this has been a visual assessment.
