Topsoil Calculator

Calculate how much topsoil you need for your project

About this calculator

The Topsoil Calculator helps you determine the exact amount of topsoil needed for gardening, landscaping, or construction projects. By inputting your area dimensions and desired soil depth, this tool calculates the required volume in cubic yards, cubic feet, or tons. This prevents overbuying expensive topsoil or running short mid-project, saving both time and money while ensuring optimal soil coverage for healthy plant growth and successful landscaping outcomes.

How to use

Enter the length and width of your project area in feet, then specify your desired topsoil depth in inches. The calculator will instantly compute the total volume needed in cubic yards and cubic feet. For purchasing purposes, it also converts to approximate tonnage based on standard topsoil density.
