How do I know how many yards to purchase?
How many yards do I need? This is a very common question. First, you need to figure out how many square feet you want to cover. To do this, see below…
For Square areas: Multiply the Length (x) the Width. This will give you the total square feet.
For example: You have 2 areas to cover with mulch. The first area is 9′ x 22′. The second one is 6′ x 30′. For the first area, 9 x 22 equals 198 square feet. The second equals 180 square feet. So total for both areas is 378 square feet.
For Circular areas: Take the Radius (which is half of the diameter) and multiply by itself. Then take that number and multiply by 3.14. This will give you the total square feet.
For example: You have a 24 foot diameter (the distance across) circle to cover with mulch. So the radius is 12. 12 x 12 equals 144. Now, take that number and multiply by 3.14. So, 144 x 3.14 equals 452 square feet.
Take your total number of square footage and divide by the number in the chart of your chosen depth. This will give you the correct amount of mulch needed.
For example: Your circle is 452 square feet. You want to cover it all with 3 inches of mulch. Take the 452 and divide by 108 (the coverage for a 3″ depth). You come up with approximately 4.2 cubic yards.
* Note: If placing an order for delivery, make sure you get enough. It would be best to round up to the nearest full yard.
Determine what depth you want for coverage and refer to the table below.
