How to Use This Calculator
- Choose your input method — enter length × width or total square feet.
- Select the desired depth of topsoil (4" is standard for new garden beds).

The Formula
Cubic Yards = (Area in sq ft × Depth in inches) ÷ 324
This divides by 12 (inches to feet) and by 27 (cubic feet to cubic yards). Combined: 12 × 27 = 324.
Weight (tons) = Cubic Yards × 1.1
Topsoil weighs approximately 2,200 lbs (1.1 tons) per cubic yard, depending on moisture content.
