How much stone do I need?
Multiply L × W × depth (ft), divide by 27 for cubic yards, then multiply by density (1.4 for crushed stone) for tons.
How deep should stone be?
2-3" for decorative beds, 4" for driveways, 6-8" for drainage applications.
How much does a ton cover?
One ton of crushed stone covers ~80-100 sq ft at 2" deep.
Crushed stone vs river rock?
Crushed stone for stability (driveways), river rock for aesthetics and drainage.
The calculator multiplies your project's length, width, and desired depth to determine total cubic yards needed. It then converts cubic yards to tons using standard density values for your selected stone type (since suppliers sell by weight, not volume). We automatically add your selected overage percentage to ensure you have enough material for natural variations in coverage and compaction.
Formula
Cubic Yards = (Length × Width × Depth) ÷ 324
Tons = Cubic Yards × Stone Density × (1 + Waste %)
