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

Aggregate Coverage Formula

The following formula is used to calculate the aggregate coverage.

C = A * (D / 12) / 27

Variables:

  • C is the coverage (cubic yards)
  • A is the area to be covered (square feet)
  • D is the desired depth of the aggregate (inches)

To calculate the aggregate 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 Aggregate Coverage?

Aggregate coverage refers to the volume of aggregate material required to cover a specific area to a certain depth. Aggregate materials, such as gravel, sand, or crushed stone, are commonly used in construction and landscaping. Knowing the coverage is essential for estimating the amount of material needed for a project, ensuring that the right quantity is ordered and delivered.

How to Calculate Aggregate Coverage?

The following steps outline how to calculate the Aggregate Coverage.


  1. First, determine the area to be covered (A) in square feet.
  2. Next, determine the desired depth of the aggregate (D) in inches.
  3. Next, gather the formula from above = C = A * (D / 12) / 27.
  4. Finally, calculate the Aggregate 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 the aggregate (D) = 3 inches
