Estimate how many tons of river rock your landscaping needs. Each dimension has its own unit (in/ft/yd/m), and the material dropdown sets the density automatically.
| Area | Shape | Length | Width | Dia | Depth | Cu Yd |
|---|
Measure each area, divide the volume by 27 for cubic yards, and multiply by the density. River rock and 2-6 inch rock run lighter per yard than crushed stone because of the gaps between stones - the material dropdown sets a typical value. Switch any field's unit as needed.
