Topsoil Calculator
Calculate how many cubic yards of topsoil you need to cover an area at a given depth.
This calculator provides a material estimate for general planning purposes only. Always add a safety margin and confirm quantities with your supplier or contractor before purchasing, since real-world waste, layout and offcuts vary by project.
This calculator converts an area and desired topsoil depth into the cubic yards you'll need to order, using the standard 27-cubic-feet-per-cubic-yard conversion.
Example
- With the default values shown above, this calculator returns: Topsoil Needed (Cubic Yards) ≈ 6.17; Topsoil Needed (Cubic Feet) ≈ 166.67.
Frequently Asked Questions
What is the formula?
Cubic Yards = Area (sq ft) × Depth (feet) ÷ 27.
How deep should topsoil be for a new lawn?
A common recommendation is 4–6 inches of topsoil for a new lawn bed, though thinner top-dressing layers (0.5–1 inch) are common for existing lawns.
