Enter the area to cover and the depth of gravel to determine how much gravel you will need for your project.

Gravel Calculation Formula

The following formula is used to calculate the amount of gravel needed for your project.

Gravel Needed (cubic yards) = (Area * Depth) / 12 / 27

Variables:

  • Gravel Needed is the total amount of gravel required (cubic yards)
  • Area is the total area to be covered (square feet)
  • Depth is the depth of gravel required (inches)

To calculate the gravel needed, multiply the area by the depth, convert inches to feet, and then convert cubic feet to cubic yards.
