How Many 40Lb Bags Of Topsoil Are In A Yard?

Topsoil makes for a great landscaping material and is largely made up of sand, small rocks, clay and undecomposed organic matter, just to name a few. It’s primarily used to amend garden soil but it can be used on its own to improve soil fertility and give the plants the nutrients they need to thrive.

Topsoil weight also depends on several factors, including amount of moisture, composition and compactness. It’s mostly sold in 40lb bags and can be delivered straight to your doorstep, albeit at an additional cost.

A cubic yard is roughly measured in 3x3x3, or 3 feet of width, height and length, which equals 27 cubic feet in total. In relation to this, topsoil mostly has a 2,200 pounds per yard yield, or 80 lbs in cubic feet and a 1.1 short ton for a yard.

A 40 pound bag of topsoil gives around .50 cubic feet, .02 short tons or .018 cubic yard. With this in mind, a cubic yard measures around 27 cubic feet, thus if you’ll do the math then you’ll arrive at 54 bags (since a bag is .5 cubic feet and you need to reach 27).

In US customary measurement, it will take 54 bags of 40lb bags of topsoil to roughly fill in a cubic yard of space in your lawn or land. You can add a bag or two to compensate for soil density and moisture and just to play it safe.
