How the calculation works
Planning calculation
Volume = area × depth in feet; estimated short tons = cubic feet × entered lb/ft³ ÷ 2,000.
How to use this calculator
- 1Enter measured project dimensions and quantities.
- 2Adjust material, spacing, waste or density assumptions to match the project.
- 3Review the live planning quantities.
- 4Round purchasing quantities appropriately and confirm field conditions.
Understanding the result
For 100 square feet at 3 inches, volume is 25 ft³ or about 0.926 yd³ before settlement.
Results use the units shown beside each field and output.
Important limitations
- Moisture, composition, screening and compaction materially change density and delivered coverage.
- Tonnage is only as reliable as the entered density.

Frequently asked questions
How much topsoil for 100 ft² at 3 inches?
25 cubic feet, about 0.926 cubic yards.
Why is density editable?
Wet, dry, sandy and organic soils have different bulk weights.
Does volume include compaction?
No. Add a project-specific settlement allowance if needed.
