How to Use This Chart
- Measure your coverage area in square feet
- Decide on your depth (2, 3, or 4 inches are most common)
- Find the intersection of your square footage and depth in the table above — this gives your cubic yard requirement
- Cross-reference with the weight table to get tons for supplier pricing
For areas not exactly matching table values, interpolate between rows or use our river rock calculator for a precise result.
