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.

Overview

#57 Gravel

Crushed stone approximately 3/4 to 1 inch in size. One of the most versatile and commonly used gravel sizes in both residential and commercial construction. #57 stone is the go-to aggregate for drainage, driveways, and concrete production.

Brown Shredded Mulch

Shredded bark and wood from trees like oak, hickory, and maple. Retains moisture, suppresses weeds, and regulates soil temperature. Decomposes slowly over time, adding organic matter to the soil. Adds a natural, finished look to landscape beds.

Pros & Cons

#57 Gravel

+ Extremely versatile — works for many applications
+ Excellent drainage characteristics
+ Good compaction when combined with fines
+ Widely available nationwide
+ Cost-effective

− Too coarse for comfortable walking
− Angular edges
− Shifts under foot traffic without stabilization
− Requires a finer top layer for driveways
− Not decorative

Brown Shredded Mulch

+ Retains soil moisture reducing watering
+ Suppresses weed growth naturally
+ Insulates soil temperature
+ Decomposes to enrich soil over time
+ Attractive natural brown color

− Needs replenishing every 1-2 years as it decomposes
− Can attract termites if placed against structures
− May temporarily rob nitrogen from soil as it breaks down
− Floats and washes away in heavy rain
− Can develop mold in overly wet conditions

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.

Brown Shredded Mulch

Shredded strips of bark and wood, typically 1-4 inches long. Natural brown color that fades to gray over time. Double-shredded mulch is finer and mats together better, resisting wind and rain displacement.
