2 inches works for most decorative rock. Go deeper for driveways, drainage, or weed control.

Quick Tips

1

Rock is sold by the ton, not the yard. This calculator accounts for the average density of stone (~1.4 tons per cubic yard).

2

Lay landscape fabric first under decorative rock. It stops weeds from growing through and keeps the rock from sinking into the soil.

3

Bigger rocks need deeper coverage. Pea gravel at 2" works great, but river rock might need 3-4" to fully cover.
