Use our calculator below to determine the amount you need:
[Length] x [width] / 162 = 2 inches of coverage
Example: I have a landscape bed that is 40 feet long by 20 feet wide.
(40 x 20) / 162 = 4.94 yards
From 4.94, we recommend to round up because it is better to have a touch more than to run out, so you would need 5 total yards of material. This calculation is if the area has no plants, rocks, or any other items that would take up space where material would not be installed. If the area is heavily planted, you would use less material.
