May 04, 2011· So a #4 sieve screen uses 4 squares to make up a 1" line. You can see what I mean in the picture below. Aggregate materials are generally broken up into two classifications of size: fine and coarse aggregate. Coarse aggregates are typically sizes larger than the #4 sieve. Fine aggregates are typically sizes smaller than the #4 sieve.
