If you are having trouble figuring out how much topsoil you will need, call the friendly associates at Elliott's Garden Center for help. Tell us about your project's measurements, and the application (lawn installation, planting trees, or building landscape beds for example). The following calculations are approximate, and can be made less accurate by several variables.
To calculate how much topsoil you will need for your project you will first need to find the total amount of square feet that needs covered.
Rectangular areas are measured by multiplying the length times the width. (Example) Length 4' x Width 5' = 20 square feet.
Circles are measured by multiplying the radius (half the diameter) by itself, and multiplying that by pi (3.14). (Example) Radius 3' x 3' = 9 square feet x 3.14 = 28.26 square feet.
Triangles are measured by multiplying the length times the width then dividing that product in half. (Example) Length 4' x Width 5' = 20 square feet x .5 = 10 square feet
Next you will need to select the depth that you would like the topsoil to be installed at. If you are trying to build up height (a raised landscape bed for example) keep in mind that topsoil compacts and settles down significantly.
Divide the total sqaure feet that you would like to cover by the yield of a cubic yard of topsoil using the chart below.
Example 600 sqaure feet 2" deep
600 / 162 = 3.7 cubic yards
Yield of a cubic yard of topsoil at a depth of...
1" deep = 324 square feet
1.5" deep = 216 square feet
2" deep = 162 square feet
2.5" dep = 135 square feet
3" deep = 108 square feet
4" deep = 81 square feet
5" deep = 64 square feet
6" deep = 54 square feet
For larger depths call the associates at Elliott's Garden Center for assistance.
