What Size Gravel for Driveway?

A well-built gravel driveway uses three layers of progressively smaller stone: Base Layer (4 inches) Use #3 stone (1-2 inches) or #4 stone (1.5-3 inches). These large angular stones create a stable foundation and won't sink into soft soil. A geotextile fabric under this layer prevents the stone from migrating into the subgrade. Middle Layer (4 inches) #57 stone (3/4 to 1 inch) is the standard choice. It fills the gaps in the base layer, adds stability, and provides a transition to the finer top layer. Top Layer (2-3 inches) #8 gravel (3/8 to 1/2 inch) or crushed limestone creates a smooth driving surface. Some homeowners prefer #411 (a blend of #57 stone and stone dust) because the dust fills voids and compacts into a very firm surface. What to Avoid Avoid using pea gravel or river rock for driveways — their rounded shape means they never lock together and will constantly shift under tires, creating ruts.

#57 Gravel vs Mexican Beach Pebble: Size, Cost, and Which to Use

#57 Gravel runs about $20 per ton and Mexican Beach Pebble about $120 per ton. Compare size, drainage, compaction, and which one to use.

Overview

#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.

Mexican Beach Pebble

Mexican beach pebbles are smooth, naturally tumbled stones commonly used in modern and decorative landscaping. They are prized for their uniform shape, rich color, and polished appearance.
