Size river rock for beds, dry creeks and borders. Larger rock needs a deeper layer to look finished.
How it works
Length × width × depth gives volume, and about 1.3 tons per yard estimates the weight.
Before you order
- Use a depth around twice the width of the rock for full coverage.
- A mix of sizes looks more natural in a dry creek.
- River rock holds heat, so choose plants that can handle it.
Common questions
How deep should river rock be?
About 2 to 3 inches for small stone and 4 inches or more for rock over 2 inches wide.
Do I need fabric under river rock?
Fabric helps keep stone out of soil, though weeds can still root in debris that collects on top.
