Mulch Coverage

Heres an approximate coverage chart we keep in the office. Its pretty close, and if anything it overestimates, so you'll never run low. You can cut and paste this into word and print it out. Hope this helps!!


3 yards of soil 3/4" deep covers 1,000 sq. ft.
1 yard of soil 3" deep covers 100 sq. ft.


1 yard of mulch 4" deep covers 80 sq. ft.
1 yard of mulch 3" deep covers 100 sq. ft.
1 yard of mulch 2" deep covers 150 sq. ft.


1 yard of MOST crushed rocks is approximately 1.25 tons.

I have more stuff, and after I put this here I decided to stop and ask if anyone wants to post the formulas so people can learn how to do it instead of having to ask. Lemme know!!

Length x Width x Depth = Cubic Feet

1 Cubic Yard = 27 Cubic Feet so

Total Cubic Feet divided by 27 = Cubic Yards

So to answer the first post: 27 Cubic feet divided by .167 (2" is .167 of a foot) = 161.7 square feet

If you know the area and the depth that you need to cover, and want to know how much material to get:
Length x Width x Depth divided by 27 = Cubic Yards needed.

Just convert the depth from inches to a fraction of a foot.

Here's the numbers so you don't have to do the math
1" = .083ft, 2" = .167ft, 3" = .25ft, 4" = .333ft,
5" = .417ft, 6" = .5ft, 7" = .583ft, 8" = .667ft,
9" = .75ft, 10" = .833, 11" = .917, 12" is a secret;)
