Landscape materials such as topsoil, mulch, and river rock are commonly sold by the rough yard, or partial yard.
A yard of material is 27 cubic ft. In other words a 9'x3'x1' space.
Check out our "Tips On Mulching Page" so that you do this important garden task correctly.
|Enter the area and the desired thickness of topsoil or mulch and click on "Calculate."(see below for area calculation hints)|
Draw your site as accurately as possible to scale. Use the following formulas to determine area:
Rectangle: Area = length x width
Circle: Area = 3.1416 x the square of the radius
Triangle: Area = 1/2 x length of base x length of height
Hint #1:If you are measuring odd or complex shapes, divide the area into combinations of rectangles, triangles, and/or circles. Measure these smaller areas and total the areas for them.
Hint #2:To determine topsoil requirements for areas of varying grade you may have to estimate an average fill depth.
