FORMULAHow much product do you need?


Calculate your square footage of area (SQ. FT. = length in feet x width in feet)

If you have more than one area just add up the total square footage.


Decide depth of product.

  • Mulch (2″-3″)
  • Soil and Soil Amendments (site and job specific)
  • Rock (Patio 3″-6″/Driveway 6″-12″)


Divide SQ Footage by appropriate depth.

  • 1″ Depth: SQ Footage ÷ 325 = Cubic Yards
  • 2″ Depth: SQ Footage ÷ 162 = Cubic Yards
  • 3″ Depth: SQ Footage ÷ 108 = Cubic Yards
  • 4″ Depth: SQ Footage ÷ 81 = Cubic Yards
  • 5″ Depth: SQ Footage ÷ 65 = Cubic Yards
  • 6″ Depth: SQ Footage ÷ 54 = Cubic Yards
  • 8″ Depth: SQ Footage ÷40 = Cubic Yards
  • 12″ Depth: SQ Footage ÷ 27 = Cubic Yards
