Our construction materials calculator will help you determine how many cubic yards of materials you need to fill your coverage areas. Our cubic yard calculator will calculate square feet into cubic yards and allows you to enter up to 7 different square or rectangle areas (front yard, backyard, driveway, etc.) and up to 4 circular areas.

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
(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.

* 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.
