Sieve Sizes

Sieves of various mesh sizes are used in stacks (largest mesh size to smallest) to divide samples into a range of size fractions. Large mesh openings are typically 1 inch (25.4 mm) to 1/4 inches (6.35 mm) while small mesh openings are typically specified as 3 1/2 to 400 (corresponding to the number of openings per linear inch in the sieve plate).
