1 yard of dirt is one cubic yard, which equals 27 cubic feet and is best pictured as a 3 ft × 3 ft × 3 ft cube. At typical yard work depths, it covers roughly 100 square feet at 3 inches deep (about 160 sq ft at 2 inches and about 80 sq ft at 4 inches). A yard of soil usually weighs around 1,000–1,200 lb when dry and can be 2,000–3,000 lb when wet.
If you are pricing your project, expect bulk topsoil or fill to run about 25–55 dollars per cubic yard before delivery in many areas. Buying by the bag, you would need 27 bags at 1.0 cu ft each, 36 bags at 0.75 cu ft, or 54 bags at 0.5 cu ft to equal 1 yard of dirt. That quick math helps you compare bag versus bulk and plan delivery, tools, and time.
What is 1 yard of dirt? Quick answer and fast conversions
One cubic yard is a standard landscaping volume. Think of a cube three feet in each direction. That’s 27 cubic feet of material. In practical terms, the coverage depends on depth. As a rule of thumb, one yard covers about 100 square feet at 3 inches deep, about 160 square feet at 2 inches, and about 80 square feet at 4 inches. Because projects rarely have perfectly flat subgrade and soil settles a bit after watering and foot traffic, most pros order a little extra.
Weight varies with moisture and soil mix. Dry screened topsoil can be near 1,000–1,200 lb per yard; saturated loads can be 2,000–3,000 lb. Converting to tons, that’s roughly 0.5–0.6 tons dry and up to about 1.0–1.5 tons when wet. If you buy in bags, a full yard equals 27 one‑cubic‑foot bags, 36 bags at 0.75 cu ft, or 54 bags at 0.5 cu ft, and the effective cost per yard from bags is commonly far higher than bulk once your volume approaches half a yard or more.
| Depth (inches) | Square feet covered per 1 cubic yard | Cubic yards needed for 100 sq ft |
|---|---|---|
| 2 | ≈ 160–162 | ≈ 0.62 |
| 3 | ≈ 100–108 | ≈ 0.93 |
| 4 | ≈ 80–81 | ≈ 1.23 |
| 6 | ≈ 54 | ≈ 1.85 |
| 8 | ≈ 40–41 | ≈ 2.47 |
| 12 | 27 | ≈ 3.70 |

How much dirt do you need? The 1-yard calculation made easy
Use a simple formula to compute cubic yards: (Length × Width × Depth in feet) ÷ 27. This works for rectangles, and you can break irregular shapes into rectangles and triangles, then sum the volumes. For a circular bed, use area = π × radius² (in feet), multiply by depth in feet, then divide by 27.
Depth guide by use:
- Topdressing or lawn leveling: 1–2 inches
- New garden beds or overseeding areas: 3–4 inches
- Raised beds: 8–12 inches (or the internal height of the bed)
Worked examples:
- 10 ft × 10 ft bed at 3 inches (0.25 ft): Volume = 10 × 10 × 0.25 = 25 cu ft. Yards = 25 ÷ 27 ≈ 0.93 yd. Order 1.0 yd (add a small buffer).
- 12 ft × 20 ft area at 2 inches (0.167 ft): Volume = 12 × 20 × 0.167 ≈ 40 cu ft. Yards = 40 ÷ 27 ≈ 1.48 yd. Order 1.6–1.7 yd after buffer.
- Raised bed 4 ft × 8 ft × 1 ft deep: Volume = 4 × 8 × 1 = 32 cu ft. Yards = 32 ÷ 27 ≈ 1.19 yd. Order 1.25–1.3 yd after buffer.
Round up smartly and add 5–15 percent for settling, grade variation, and spillage. The fluff factor is real: soil is aerated when loaded and will compact after watering and foot traffic. If you’re right on the line between two quantities, the extra quarter yard can save a second trip or another delivery fee.
1 yard of dirt cost: prices, delivery, and the bag vs bulk break-even
Bulk pricing varies by region, soil quality, and supplier. Typical ranges in many US markets:
- Fill dirt (unscreened, for grading): about 30–35 dollars per yard
- Screened topsoil (lawns, general beds): about 29–45 dollars per yard
- Garden/compost blends (enriched mixes): about 50–65+ dollars per yard
Delivery fees often add 50–150 dollars depending on distance, fuel, and whether the load is below the supplier’s minimum. Small loads can push the effective price per yard up, while full truckloads reduce it. Some companies price by the ton, especially for fill; moisture makes loads heavier, so a rainy week can nudge the ticket higher when priced by weight.
| Bag size (cu ft) | Typical bag price ($) | Bags per cubic yard | Effective $/yard at that price | Notes (when bags make sense) |
|---|---|---|---|---|
| 0.5 | 3.00–5.00 | 54 | ≈ $216 @ $4.00 | Convenient for very small areas or tricky access |
| 0.75 | 5.00–7.00 | 36 | ≈ $216 @ $6.00 | Good if you need under ~0.4 yard |
| 1.0 | 7.00–9.00 | 27 | ≈ $216 @ $8.00 | Still costlier than bulk once delivery is shared |
Break-even idea: Suppose you need 0.4 yard (about 11 cu ft). That’s roughly 22 bags of 0.5 cu ft. At $4 per bag, you’d spend about $88 at the store. If your local bulk topsoil is $35 per yard plus a $75 delivery fee, your total is about $110 for a full yard delivered. Bags are less cash for small jobs without delivery, but once you approach 0.5–1.0 yard or can split delivery across several beds, bulk is usually the better value and far less lifting.
Moisture and season matter. Spring demand can raise prices and extend delivery timelines. After heavy rain, bulk loads may be heavier and messier; if pricing is by the ton, ask for a current moisture note so you can avoid surprises.
Weight, transport, and labor: moving a yard without regrets
Because moisture swings matter, think in ranges. A yard of topsoil can be 0.5–0.6 tons when dry and up to about 1.0–1.3 tons when wet. Garden mixes with lots of organic matter tend to be lighter; dense clay fill can be heavier. If a supplier sells by ton, ask how they estimate yards-to-tons so you can order to a target volume.
| Material | Dry lb/yd | Wet lb/yd | Approx tons/yd | Safe fraction of a 1,500 lb payload (dry vs wet) | Wheelbarrow trips (2/3/6 cu ft) |
|---|---|---|---|---|---|
| Fill dirt | ≈ 1,200–1,600 | ≈ 2,400–3,000 | ≈ 0.6–1.5 | ≈ 1.0 yd dry; ≈ 0.5–0.6 yd wet | 14 / 9 / 5 |
| Screened topsoil | ≈ 1,000–1,200 | ≈ 2,000–2,600 | ≈ 0.5–1.3 | ≈ 1.0 yd dry; ≈ 0.6–0.75 yd wet | 14 / 9 / 5 |
| Garden/compost mix | ≈ 900–1,100 | ≈ 1,800–2,400 | ≈ 0.45–1.2 | ≈ 1.0 yd dry; ≈ 0.6–0.8 yd wet | 14 / 9 / 5 |
Pickup payload reality: Many half-ton pickups list payload limits around 1,500–2,000 lb on the door sticker. A wet yard of topsoil can exceed that. Carrying a full yard in a small pickup risks overloading the suspension and tires. Safer plan: ask the yard to load a half yard or two-thirds yard and make multiple trips, or choose delivery to a tarp on your driveway.
How long does it take to move a yard by hand? With a 6 cu ft wheelbarrow, plan on about five heaping trips. With a 3 cu ft contractor barrow, about nine trips. With a smaller 2 cu ft homeowner barrow, roughly 14 trips. Depending on distance and terrain, a solo homeowner usually spends 30–90 minutes moving one yard, plus spreading time. Good tools help: a square-point shovel for loading, a landscape rake for grading, and a watering wand to settle the soil in place. For more ambitious reshaping or multiple yards, renting a mini skid steer for a few hours can be a smart tradeoff.
Which dirt to buy (and when 1 yard is right)
Not all “dirt” is the same, and picking the right material prevents rework:
- Fill dirt: Best for raising grade, backfilling behind walls, or filling low spots beneath a topsoil cap. It can be rocky and clumpy, and is not ideal for planting.
- Screened topsoil: General purpose for lawns and beds. Screening removes sticks and clods for easier spreading and smoother grading.
- Garden or compost mix: A blend of topsoil with compost and sometimes sand. Great for vegetable beds and new planting areas needing more organic matter.
Drainage and texture matter. Sandy loam drains faster and is easier to work; heavy clay holds water longer and can compact. Many suppliers list particle size and organic matter percentages; when in doubt, ask for a small sample or the published spec. For family yards where organic inputs are a priority, this piece can help you think through materials across the season: Why You Should Use Organic Products On Your Lawn And In Your Landscaping.
When is 1 yard the right order? It’s a sweet spot for topdressing a 10×10 area at about 3 inches, filling a single mid-size raised bed, or creating a few new planting pockets. If you’re regrading a full lawn or building several large beds, you may need 2–6 yards or more, and delivery becomes far more efficient than bags or pickup shuttles.
Avoid common mistakes and verify your delivery
Order the right depth for the job, then add 5–15 percent extra for settling and the inevitable unevenness of real yards. Under-ordering forces compromises, like spreading too thin and seeing bare spots after the first rain.
Verify volume on delivery:
- Measure the pile: Quickly check length × width × average height in feet for the dumped pile. Divide by 27 to estimate yards.
- Loader bucket count: Many yards know the capacity of their loader bucket. Ask how many buckets they loaded for your order.
- Scale ticket when priced by weight: If the supplier sells by ton, the ticket shows gross and tare weights. Ask their conversion for your material to estimate the yardage you received.
Site readiness reduces hassles: Confirm the truck can access the dump spot, clear cars and kids’ gear, and lay a tarp to keep soil off pavers and out of gravel. If it’s been raining, remember wet loads weigh more; you do not want to exceed your driveway or trailer limits. If you have to stage soil on the lawn, plan to use it quickly to avoid smothering turf.
