Ces m\u00e9thodes sont appel\u00e9es, respectivement, m\u00e9thode par comparaison, m\u00e9thode par interception, et m\u00e9thode planim\u00e9trique. La m\u00e9thode par comparaison (de l&#039;\u00e9chantillon avec des images type) est la plus commode, et elle est suffisamment pr\u00e9cise pour la plupart des besoins commerciaux. La m\u00e9thode par interception (Heyn), comme la m\u00e9thode planim\u00e9trique (Jeffries), permet d&#039;obtenir une pr\u00e9cision sup\u00e9rieure d&#039;\u00e9valuation de la dimension du grain. En cas de litige, il est recommand\u00e9 d&#039;utiliser l&#039;une de ces m\u00e9thodes, apr\u00e8s accord entre les parties int\u00e9ress\u00e9es.
