You're standing at the landscape supply yard. And the loader operator is waiting. You know you need topsoil — maybe for a new garden bed, maybe to level out that low spot in the backyard that turns into a swamp every spring. But the guy asks the question that stops everyone cold: "How many yards?
You told him tons. Also, he sells by the yard. Now what?
Here's the short answer: one ton of topsoil is roughly 0.But that number comes with an asterisk the size of a dump truck. 75 cubic yards. Let's unpack why That's the part that actually makes a difference..
What Is a Yard of Topsoil Anyway
A cubic yard is a volume measurement. Picture a box three feet wide, three feet long, and three feet deep. That's 27 cubic feet. One cubic yard Not complicated — just consistent..
A ton is weight. Two thousand pounds.
They're not the same thing. So not even close. And this is where most people — contractors included — get tripped up That alone is useful..
Topsoil isn't a uniform product. Which means it's not concrete. It's not mulch. Plus, it's dirt, organic matter, sand, clay, moisture, and whatever else ended up in the pile. Still, a "yard" of topsoil from Supplier A might weigh 2,200 pounds. The same volume from Supplier B might hit 2,800. On the flip side, wet soil weighs more. Sandy soil weighs less. Screened soil weighs different than unscreened.
So when someone says "a yard and a half per ton," they're giving you a rule of thumb. Not a guarantee Worth keeping that in mind..
The math behind the estimate
Most landscape suppliers settle on a standard conversion: 1 cubic yard of topsoil ≈ 1.5 tons. In real terms, 3 to 1. Day to day, 67 to 0. Flip that around and you get 0.75 yards per ton Small thing, real impact. Less friction, more output..
Why the range? Compost-heavy blends? Freshly screened topsoil after a rainstorm can run 1.Practically speaking, bone-dry sandy loam might come in at 1. Worth adding: moisture content is the big one. Even so, 5 tons per yard easy. 1. Even lighter That alone is useful..
Why It Matters / Why People Care
Order wrong and you're either short — paying for a second delivery plus a minimum load fee — or you've got a mountain of dirt in your driveway that the HOA is already sending nastygrams about Less friction, more output..
I've seen both. But a buddy of mine ordered "three tons" for a raised bed project. Here's the thing — got delivered 2. Because of that, 25 yards. Looked like a molehill. Even so, he needed double. Second delivery cost him $120 extra because the minimum was four yards.
Flip side: another guy ordered "five yards" thinking it was five tons. Ended up with nearly seven tons of wet clay-loam. So his driveway cracked. The skid steer rental to move it cost more than the soil And it works..
This isn't academic. On top of that, it's your wallet. But your weekend. Your back.
How It Works (or How to Calculate What You Need)
Let's walk through the real-world process. Not the textbook version — the version that works when you're standing there with a tape measure and a calculator app It's one of those things that adds up..
Step 1: Measure your area in cubic feet
Length × width × depth. All in feet.
Say you're filling a bed that's 12 feet long, 4 feet wide, and you want 6 inches of fresh topsoil. That's 0.5 feet deep Practical, not theoretical..
12 × 4 × 0.5 = 24 cubic feet.
Step 2: Convert to cubic yards
Divide by 27.
24 ÷ 27 = 0.89 cubic yards. Consider this: call it 0. 9.
Step 3: Convert to tons (if your supplier sells by weight)
Multiply by the density factor. So use 1. 35 as a middle-ground average for typical screened topsoil.
0.9 × 1.35 = 1.215 tons.
So you'd order 1.25 tons — or ask for 1 yard and confirm the weight with the supplier.
Step 4: Add a waste factor
Always. Always add 10–15%. Soil settles. You spill some. In practice, the loader bucket isn't precise. The bed isn't perfectly rectangular.
0.9 yards × 1.15 = 1.035 yards. Round up to 1.25 yards or 1.5 tons.
Better to have a little extra for potting containers or patching lawn low spots than to come up short.
What if the supplier only sells by the scoop?
"Scoop" is not a unit. In real terms, it's a bucket. Practically speaking, a skid steer bucket might be 0. So 5 yards. A front-end loader bucket might be 2.5. In real terms, ask: "How many cubic yards is your bucket? " Get it in writing on the ticket. Don't trust "two scoops" unless you know the bucket size Simple, but easy to overlook. That's the whole idea..
Common Mistakes / What Most People Get Wrong
Mistake 1: Confusing "yard" with "ton" in conversation. You say "three yards." They hear "three tons." You get 4.5 yards. Write it down. Confirm on the order ticket. Read it back Turns out it matters..
Mistake 2: Assuming all topsoil weighs the same. It doesn't. A yard of wet, heavy clay topsoil can push 3,000 pounds. A yard of light, sandy, compost-rich blend might be 1,800. Ask the yard for their current weight per yard. They know. They weigh every load.
Mistake 3: Measuring depth in inches but forgetting to convert. Six inches is 0.5 feet. Not 6. This error alone has buried more projects than bad weather.
Mistake 4: Ordering "clean fill" instead of topsoil. Clean fill is subsoil. Little organic matter. Compacts hard. Drains poorly. Grass struggles. Gardens fail. Topsoil has organic content — usually 5–10% minimum. Ask for the spec sheet. If they don't have one, keep looking.
Mistake 5: Not accounting for compaction. Freshly dumped soil is fluffy. It settles. Rain, foot traffic, time — it all compresses. That 6-inch layer becomes 4 inches in a month. Order for the finished depth after settling, not the fluffed depth at delivery.
Practical Tips / What Actually Works
Call ahead. Ask three questions.
- "What's your current weight per cubic yard for screened topsoil?"
- "What's your minimum delivery?"
- "Can you dump in the driveway, or do I need a waiver for street delivery?"
Get a sample first. Most yards will let you fill a 5-gallon bucket. Take it home. Feel it. Smell it. Check for rocks, roots, trash. If it smells sour or looks gray-blue, it's anaerobic — bad biology. Walk away Turns out it matters..
Schedule delivery for a dry day if possible. Wet soil is heavier (you pay for water weight) and a nightmare to move with a wheelbarrow. It sticks. It clumps. It ruins your lawn if you have to drive across it That's the part that actually makes a difference..
Rent a skid steer for anything over 3 yards. Seriously. A yard of topsoil is ~1.35 tons. Three yards is four tons. That's 80+ wheelbarrow
loads. A skid steer with a 2-yard bucket can move it in under an hour. Rentals start around $150/day but save you days of backbreaking labor Simple, but easy to overlook..
Pro tip: Have your wheelbarrow loaded before the truck arrives. Nothing kills momentum like waiting for someone to push a load across the yard while the driver sits idle Nothing fancy..
The Math That Actually Matters
For rectangular areas: Length × Width × Depth (in feet) = cubic feet. Divide by 27 = cubic yards And that's really what it comes down to..
For circular areas: π × radius² × depth = cubic feet. Divide by 27 = cubic yards Easy to understand, harder to ignore..
Example: 20×15 feet at 6 inches deep = 300 × 0.Which means 5 = 150 cubic feet ÷ 27 = 5. Consider this: 56 yards. Round up to 6 yards.
Reality check: Add 10% for waste and overlap. That 6-yard job? Order 7 Small thing, real impact..
Quality Indicators (What to Look For)
Good topsoil should pass the "squeeze test": Grab a handful. Even so, it should form a loose ball that crumbles when poked. Should smell like earth, not chemicals. No plastic chunks, concrete debris, or chemical bags.
Avoid anything labeled "municipal compost" or "green waste" unless you've verified it's pathogen-free. Your vegetable garden will thank you Worth keeping that in mind..
Final Numbers (Quick Reference)
- 1 cubic yard covers 324 square feet at 1" deep
- 1 cubic yard covers 162 square feet at 2" deep
- 1 cubic yard covers 81 square feet at 4" deep
- 1 cubic yard covers 54 square feet at 6" deep
- 1 cubic yard weighs 1,800-3,000 pounds depending on type
Bottom Line
Topsoil delivery is logistics, not rocket science. Measure twice, order once, confirm everything in writing, and always get a sample. The difference between a successful landscaping project and a muddy disaster often comes down to asking the right questions before the truck arrives The details matter here..
Your garden won't know the difference between 6.2 and 6.On the flip side, 8 yards, but your wallet will feel the impact of ordering too little. When in doubt, order more. You can always spread the excess; you can't unspread dirt you forgot to order.
