How much will a cubic yard of compost cover?
A cubic yard will cover one hundred eight square feet three inches deep. For other depths, measure the width (in feet) x length (in feet) x depth (in feet). You now have the volume in cubic feet. Divide that number by 27 (the number of cubic feet in a cubic yard) and you will have the quantity, in cubic yards, needed for your area. Click here for coverage chart.
