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.

Sizes & Colors

#57 Gravel

#57 gravel consists of angular crushed stone pieces ranging from 3/4" to 1" in diameter. Color depends on the quarry source — typically gray, blue-gray, or brown. The stones are angular and irregular, which helps them interlock.

River Rock

River rock comes in a wide range of sizes: small (1"–2"), medium (2"–3"), large (3"–5"), and boulders (5"+). Natural colors include gray, brown, tan, white, black, and multi-colored blends. Mexican beach pebbles offer polished black and gray options.
