*A grit size is defined by the distribution of grits retained on a sieve set up that meets the requirements of ANSI Table 2 or 3. The numbers in the two sieve columns in this chart represent the midpoint sieve for the grading of the corresponding grit size. We've chosen to show the midpoint sieve since more material will be retained on this sieve than on any other in the sieve set up.
