How Much Does a Yard of Topsoil Weigh?

A cubic yard of topsoil weighs about as much as a small car's worth of dirt, and the exact number swings by 1,000 lb depending on one thing: how wet it is. That single variable is why no two charts agree, and why your supplier quotes a range instead of a hard figure.

This page gives you the working range, the math behind it, and the one weight question that catches first-time bulk buyers: whether a full yard will even fit in your truck.

What a yard of topsoil actually weighs

Plan on 2,000 to 2,700 lb per cubic yard for ordinary screened topsoil, dry to moist. That is about 1.1 to 1.3 US tons. Use 1.2 tons as your working figure when you call the supplier.

The reason it is a range, not a single number, is water. Dry, loose topsoil sits at the light end. Add rain or recent watering and the same yard gets heavier fast, because water fills the gaps between soil particles.

The Two Rivers-Ottauquechee Regional Commission material-weight chart lists topsoil at 2,050 lb loose, 2,565 lb packed, and 3,375 lb wet per cubic yard. So a soaked yard can outweigh a dry one by more than half a ton.

Composition shifts it too. Sandy or rocky topsoil weighs more than soil rich in organic matter, since plant material is lighter than mineral grit. But moisture is the variable that moves the number most.

How weight and coverage connect to the math

Weight follows from volume, and volume is simple. You measure your project in square feet, then convert to cubic yards with one shortcut.

cubic yards = square feet × depth (inches) ÷ 324

That 324 is just 12 × 27 folded together. The 12 turns inches of depth into feet, and the 27 turns cubic feet into cubic yards. Once you have cubic yards, multiply by 1.2 for the tonnage to quote.

Here is the coverage per yard at common depths, straight from the conversion. Depth drives everything, so lock yours in before you size the order.

So one yard spreads across about 108 square feet at 3 inches, weighs roughly 2,400 lb at the 1.2-ton working figure, and that is your whole picture in two numbers. For sizing a full project by area, the how much topsoil do I need guide runs the same ÷324 shortcut end to end.

Dry vs wet vs screened: what changes the number

Three words on a delivery slip change what your yard weighs. Here is what each one means for the scale.

Dry topsoil is the lightest, near 2,000 lb a yard. It pours and spreads easily, but a yard rarely stays dry once it is sitting in your driveway through a rain.

Wet topsoil is the heaviest, often 2,700 to 3,375 lb a yard, per the topsoil.com weight breakdown. The extra weight is pure water, and it makes the soil harder to shovel and slower to spread.

Screened topsoil has been run through a mesh to pull out rocks, roots, and clods. It is the most consistent and the kind most weight figures assume. Unscreened or "fill-grade" soil varies more, since chunks of clay or stone change the density yard to yard.

Ordering by the ton

Bulk topsoil is sold and trucked by the ton, so the tonnage is the number that matters at the supplier. Get it before you call, not as a rounded guess.

Measure your square feet. Pick your depth in inches. Divide by 324 for cubic yards, then multiply by 1.2 for tons. A 500 sq ft area at 3 inches works out to about 4.6 cubic yards, or roughly 5.5 tons.

Order 5 to 10 percent extra. Topsoil settles after it is spread and watered, and ground is rarely perfectly level, so a small margin saves a second delivery fee. Leftovers top-dress a lawn or fill a low spot.

The common mistake: overloading your truck

The weight trap that catches first-time bulk buyers is the pickup. By volume, a yard fits a half-ton truck bed. By weight, it usually does not.

A cubic yard of topsoil runs about 2,000 to 2,700 lb. A typical half-ton truck's safe payload is only about 1,000 to 1,500 lb, per Car and Driver F-150 specs. Add passengers and gear and that drops further. The yard outweighs the limit.

A yard of topsoil weighs roughly 2,000 to 2,700 lb. A half-ton truck safely carries about 1,000 to 1,500 lb. Run your exact dimensions through the Topsoil Calculator and it returns cubic yards, tons, and bags in one shot, so you know the load before the truck shows up.
