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

Straw Coverage Formula

The following formula is used to calculate the straw coverage.

SC = (A * D) / 27

Variables:

  • SC is the straw coverage (cubic yards)
  • A is the area to be covered (square feet)
  • D is the depth of straw (inches)

To calculate the straw coverage, multiply the area by the depth (converted to feet), then divide by 27 to convert the volume to cubic yards.

What is Straw Coverage?

Straw coverage refers to the volume of straw needed to cover a certain area to a specified depth. It is commonly used in landscaping and gardening to provide a protective layer for soil, help with erosion control, and assist with seed germination. Calculating the correct amount of straw coverage is important to ensure adequate protection and to avoid waste.

How to Calculate Straw Coverage?

The following steps outline how to calculate the Straw Coverage.


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