One yard of mulch covers approximately a 10' x 10' area, 3" deep. Use the chart above to see more examples, or click the CALCULATOR link to use our online calculator. To figure the yardage yourself, you'll need to use the following formula: Length x width x depth (convert inches to feet by dividing depth by 12), divide by 27. Round up to the next whole number and this will give you the number of yards that you'll need.

* The accuracy of the calculator increases as the depth of the layer of stone increases. The depth of the layer of stone laid must be twice the thickness of the size of the stone used if one expects the calculators to be accurate.
