When you go to a residental site and the customer wants mulch how do you measure for it, this is for adding mulch and also a new job where there is no mulch at all. I have always just estimated by sight and was wondering if there is a measurement or somthing more exact .

I started my business in May 03. One of my first opportunities in this business was a mulch job. I was in the same boat...how much mulch do you need. In my case I connected with a lawn & garden shop that was more than willing to help with any question I had, after all you become their customer. I was told the following, as a general rule 2 scoops* of mulch will cover approximately 100 square feet 3 inches deep. Of course the question is, how big is the scoop that is being used? In my case it was approx. 6 feet long, sorry I cannot tell you exactly how much was in a scoop. Here is another way of figuring it, I can get 3 scoops in a 4x8 utility trailer without worrying about the axel.

Hope this helps you out. Keep reading, research the threads, just about every question I could think of has been answered here. This is a great place to get information, read, read, read.

Can't we all just get a lawn?

Hey Zmak,

Basically it is just a little bit of math.

Mulch is often sold by the yard (cubic yard) so this is a volume measurement (3ft x 3ft x 3ft), (which is 27 cubic feet).

If you need to know how much mulch to get, you need two things

1) the square footage you plan to cover with the mulch

2) know how deep you are going to install it (usually 3 or 4 inches deep)

then figure out the volume you need of mulch.


1) 100 square feet of bed to cover

2) 3" deep

100 square feet x 3" (or .25 foot (3/12)) = 25 cubic feet

so with 1 cubic yard = 27 cubic feet, one yard will be enough for you.

Hope this helps.

Let it Grow

Do a search on the internet for "mulch calculator" There are some sites that have a template that you just input the numbers and it does the rest. I have created my own that I use. It is VERY helpful.

Here's a good-looking area-to-volume calculator that I made using the spreadsheet component from the free office suite, OpenOffice.

For those of you who would rather keep Mr. Gates rolling in dough by paying for MS Office, it also works in excel.

The loss adjustment is handy when you're using irregular objects which settle after a trip in the dump truck. I use 103% to 105% adjustment for 1.5" river rock, for example.
