#411 Gravel vs #57 Gravel: Size, Cost, and Which to Use

#411 Gravel

#57 Gravel

The 57 comes from the ASTM C33 grading table. Size #57 means most of the stone passes a 1-inch screen and stays on a #4 sieve (about 3/16 inch), with the bulk of it between 1/2 and 1 inch. It is "clean" stone, so there are no fines. That leaves about 35 percent air space in a pile, which is why it drains so well and why it stays loose on its own.
