Depth of Area To Be Covered
In order to determine how much landscape rock you need to purchase, you need to decide how deep you want the rock to be. If the area to be covered with landscape rock has a border around it, you should measure from the ground to the top of the border. Because the rock will settle over time, you should calculate on the high side of the border. Once you have determined how deep you want the rock to be, you can use the following information to determine how much landscape rock to order.
Calculating How Much Landscape Rock You Will Need
One cubic yard of landscape rock will cover a 10 square foot area with rock approximately 3 inches deep. If you want the landscape rock to be 6 inches deep, you will need two cubic yards of rock. A number of companies that sell landscape rock have calculators on their Web sites so you can determine exactly how much of a particular type of rock you will need for your project.
