How Do I Calculate How Much Rock I Need?

When setting out to buy decorative rock and other landscaping supplies in bulk, it’s important to first calculate exactly how much you need. Otherwise, you might not have enough to finish the job, or you may end up with way too much and don’t know what to do with the extra after completing your project. While most can recognize the importance of figuring this out ahead of time, it can be tough to know how to reliably determine the amount of rock you need. That’s what we’ll be tackling here, so read on to find out!

 

There are three important measurements you should take if you want to know how much landscaping supplies in bulk you should need – length, width, and depth.

Finding the area

The first of these two measurements will be used to determine the area you want to fill with decorative rock. Measure the length and the width of the space you want to cover in rock in feet and inches and then multiply these numbers together to get the area. We recommend doing the measurements and multiplication in inches first and converting the number into feet to avoid any confusion, and so you get a more accurate number.

Identifying depth

After finding the area, you’ll need to determine the depth of the space. Think of it as the distance between the ground and where you want the top layer of rock to be. Depending on the depth you choose, some digging to lower the ground level may be required. This will obviously vary from one project to another and depend on your preferences. For most projects that require landscaping supplies in bulk, like replacing the grass in your front yard with decorative rock, two inches should suffice. However, this can depend on the kind of rock and size you’d prefer. As a general rule of thumb, the larger the individual rock is, the deeper you’ll want it.

Armed with this knowledge, you should be able to estimate how much rock you’ll need much more confidently and accurately.
