Topsoil Calculator – Estimate How Much Soil You Need

Planning a landscaping project or garden bed installation? Our Topsoil Calculator helps you figure out exactly how much topsoil you need based on the area and depth of your project. Avoid under- or over-ordering and save money and effort.

How to Use the Topsoil Calculator

  1. Enter the length and width of the area you want to cover (in feet or meters).
  2. Specify the depth of soil you require (in inches, feet, or cm).
  3. The calculator will return the total volume in cubic feet, cubic yards, and tons.

Formula Used

Volume = Length × Width × Depth

Units are automatically converted based on your input to give cubic feet, cubic yards, or tons of topsoil.
