Topsoil Calculator
Work out how much topsoil you need to level a lawn or fill raised beds. Enter the area and depth to get cubic yards and an estimated weight.
Topsoil calculator
Volume is exact geometry. Weights and bag counts assume typical densities and bag yields — treat them as an estimate, not a quote.
How to use it
- Measure the length and width of the area in feet.
- Set the depth in inches.
- Pick the material, then read off the cubic yards (and bags or tons) you need.
The calculator multiplies area by depth for an exact volume, then converts to cubic yards and estimates weight or bag count from typical material figures.
Frequently asked questions
- How much topsoil do I need?
- Multiply the area by the depth and convert to cubic yards. To add 2 inches over 1,000 sq ft you need about 6.2 cubic yards.
- How much does a cubic yard of topsoil weigh?
- Roughly 1.1 to 1.4 US tons depending on moisture and organic content.
- How deep should topsoil be?
- 4–6 inches for new lawns and 6–12 inches for garden or raised beds, depending on what you are growing.
