Enter the area to be covered and the desired depth of topsoil to calculate the required topsoil coverage in cubic yards. This calculator helps in determining the amount of topsoil needed for landscaping projects.

Topsoil Coverage Formula

The following formula is used to calculate the topsoil coverage.

C = A * (D / 12) / 27

Variables:

  • C is the coverage needed in cubic yards
  • A is the area to be covered in square feet
  • D is the depth of topsoil in inches

To calculate the topsoil coverage, multiply the area by the depth (converted to feet by dividing by 12), then divide the result by 27 to convert cubic feet to cubic yards.

What is Topsoil Coverage?

Topsoil coverage refers to the volume of topsoil required to cover a specific area to a certain depth. It is commonly used in gardening and landscaping to ensure that plants have enough soil for proper growth. The coverage is typically measured in cubic yards when dealing with large quantities.

How to Calculate Topsoil Coverage?

The following steps outline how to calculate the Topsoil Coverage.


  1. First, determine the area to be covered (A) in square feet.
  2. Next, determine the desired depth of topsoil (D) in inches.
  3. Use the formula from above = C = A * (D / 12) / 27.
  4. Finally, calculate the Topsoil Coverage (C) in cubic yards.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Area to be covered (A) = 500 square feet

Desired depth of topsoil (D) = 3 inches
