Step 1- Determine your Coverage Area- We offer 2 types of calculators, 1 is a “Box” coverage area calculator for calculating square or rectangular areas. The 2nd is to calculate “Circular” areas.

  • Box coverage area- input your measurements (Length x Width) into the "Area" fields.
  • Circular coverage area input your diameter measurement

Box Coverage Area:
Area 1
Area 2
Area 3
Area 4
Area 5
Area 6
Area 7
 Width (feet) >>>
 Length(feet) >>>
Box Area (sq. feet)

Circular coverage area
Area 8
Area 9
Area 10
Area 11
Diameter (feet) >>>
Circular Area (sq. feet)

Step 2- Enter desired materials depth- Input the depth in inches; the calculator will automatically estimate the required materials in cubic yards.

Enter desired materials depth: >>>
Total coverage area is
square feet
Estimated materials required is
cubic yards


* The materials calculator offers 7 “Box” area fields and 4 “Circular” area fields for you to calculate multiple areas simultaneously. (back yard, front yard, driveway, garden, etc..)
* The materials calculator works for construction materials smaller then ¾” in size, including Topsoil, Dirt, Sand, Stone, Gravel, DGA, Stone Dust and Aggregate.
