How Much Does a Yard of Soil Weigh? Calculator
Estimate the weight of a cubic yard of soil by type, moisture, and quantity. Useful for trailer loads, truck capacity, and delivery planning.
- Topsoil at damp moisture weighs roughly 2,300 lb per cubic yard — heavier than average, plan for sturdy hauling.
- Your 1,500 lb payload can carry about 0.65 yd³ of this soil per trip. ⚠️ A single full load of 1 yd³ would exceed your payload — split into 2 trips.
- Moisture matters: the same 1 yd³ would weigh 2,000 lb dry vs 3,000 lb saturated — a swing of 1,000 lb.
- Delivery framing: at 1.15 tons, this load is a standard small dump-truck delivery.
Knowing how much a yard of soil weighs is essential before you rent a trailer, fill a pickup bed, or order bulk delivery. A cubic yard of dry topsoil typically weighs about 2,000 lb, but wet clay can exceed 3,000 lb, and lightweight potting mix may be under 1,000 lb. This calculator converts any volume of soil, sand, mulch, or compost into pounds and tons based on soil type and moisture, so you can match your load to your vehicle's payload rating without overloading axles or springs.
Soil density depends on three things: mineral composition, organic content, and water. A half-ton pickup rated for 1,000 lb of payload can safely haul roughly half a cubic yard of damp topsoil — not the full yard most people assume. The math also matters for raised beds: a 4 ft × 8 ft × 12 in bed needs about 1.2 cubic yards, which can weigh anywhere from 2,400 to 3,600 lb depending on the blend. Enter your numbers below to get a precise estimate in both pounds and tons.
How it works: Pick a soil type, set moisture, enter volume, and the calculator multiplies by a density factor calibrated to landscaping industry averages.
Overloading a vehicle's payload by more than 10% damages suspension, brakes, and tires, and voids most insurance coverage in the event of an accident. If the calculator shows weight above your vehicle's payload rating, split the load — do not 'just try it'. Saturated clay or sand can exceed 4,000 lb per cubic yard. Never assume a full level pickup bed is safe to drive home; a standard 6.5 ft truck bed holds about 2 cubic yards, which can weigh over 8,000 lb when wet — far beyond any pickup's legal payload.
Soil Weight Guide: Cubic Yards, Tons, and Truck Loads

How Much Does a Yard of Topsoil Actually Weigh?
A cubic yard of screened topsoil weighs roughly 2,000 lb dry and 2,300–2,600 lb at the typical damp-to-wet moisture you'll find at a landscape supply yard. That works out to about one US ton, which is where the common 'a yard of soil weighs a ton' rule of thumb comes from. But it's an average, not a guarantee — heavy clay topsoil straight out of the ground can hit 2,800 lb damp, while a screened topsoil blended with compost might be closer to 1,700 lb. Always ask your supplier for the bulk density spec sheet if your hauling margin is tight.
Why Moisture Changes Everything
Water weighs about 8.34 lb per gallon, and soil can hold a surprising amount. A cubic yard of dry topsoil contains roughly 25–35% pore space. Fully saturate those pores and you've added roughly 400–600 lb of water to the same volume — without changing the visible quantity. The practical rule: if soil has been rained on within 24 hours, treat it as 'wet' (+30%); if it's been sitting in puddles or you can squeeze water out of a handful, treat it as 'saturated' (+50%). This is the number-one reason rented trailers blow tires on the way home.
Which Soil Type Should You Choose for Your Project?
Different jobs call for different soils, and the weight difference between them can double your hauling cost. Fill dirt (subsoil with rocks and clay) is heavy and cheap — perfect for grading and backfilling holes, but not for growing. Screened topsoil is the all-rounder for lawns and shallow planting. For raised beds, blend topsoil with 30–40% compost to drop density to roughly 1,700 lb/yd³ and improve drainage. For pots and elevated planters where weight matters structurally, use a peat-and-perlite potting mix at under 1,000 lb/yd³. Clay should generally be avoided unless you're sealing a pond.
How the Calculator Handles Unit Conversions
Internally the calculator works in cubic yards and pounds — the two standard units of US bulk landscape supply. If you enter volume in cubic feet, it divides by 27 (since 1 yd³ = 27 ft³). Cubic meters convert at 1 m³ ≈ 1.308 yd³. Gallons convert at 1 yd³ ≈ 202 US gallons, useful when buying bagged soil where packaging is measured by volume. Weight outputs convert from pounds: divide by 2,000 for US short tons, multiply by 0.4536 for kilograms, divide by 2,205 for metric tonnes. The selected display unit doesn't change the math — only how the result is presented.
Common Mistakes That Lead to Overloaded Vehicles
The biggest mistake is confusing payload with towing capacity — they're different numbers, and payload is almost always smaller. Check the yellow sticker on the driver's door jamb, not the marketing brochure. The second mistake is assuming a 'half-ton' truck can carry half a ton; modern half-tons are named for an obsolete 1960s rating and many are limited to 1,200–1,700 lb of actual payload once passengers and fuel are accounted for. The third mistake is forgetting that you also need to subtract the trailer's tongue weight or the weight of the driver, passengers, and tools already in the bed.
Bulk Delivery vs Bagged Soil: When Does Each Win?
Bagged soil at retail typically sells in 40 lb or 1 ft³ bags, which means you need 50 bags (40 lb each) or 27 bags (1 ft³ each) to make a single cubic yard. At $4–7 per bag in 2026, that's $108–189 per cubic yard — versus $30–50 per yard delivered in bulk. Bulk wins decisively above about 0.75 yd³, but bagged wins for tight access (carrying through a house), small projects under 6 ft³, or when you don't have a place to dump a delivered pile. Bagged soil is also drier and more consistent, which is why specialty mixes for seed-starting are almost always bagged.
What If My Result Looks Wrong?
If the calculator returns a weight that seems way off, check three things in order. First, volume units: confusing cubic feet with cubic yards is a 27x error and is the most common bug report. Second, moisture: if you ordered 'fresh' soil that arrived steaming, it's saturated and will weigh 50% more than the dry density. Third, soil type: 'garden soil' at a big-box store is usually a compost-heavy blend (~1,400 lb/yd³), while 'topsoil' from a landscape yard is mineral-heavy (~2,000 lb/yd³). The calculator can't see your actual material — match the selection to what you're really buying.
How This Calculator Works: Methodology & Parameter Explanations
Core formula:
Weight_lb = Volume_yd³ × DryDensity_lb_per_yd³ × MoistureFactorwhere:
Volume_yd³— Volume of soil in cubic yards (after unit conversion) (yd³)DryDensity— Dry bulk density for the chosen soil type (lb/yd³)MoistureFactor— Multiplier for water content (1.00 dry → 1.50 saturated)
How to apply: Multiply the result by 1.10 if you want a safety margin for your vehicle's payload, since real-world soil density varies ±10% depending on screening, source, and recent weather. Compare the final pound figure against the payload rating on your driver-side door sticker — never the towing capacity.
Worked example: For a 4 ft × 8 ft × 12 in raised bed filled with damp topsoil: volume is 32 ft³, divided by 27 gives 1.185 yd³. Topsoil dry density is 2,000 lb/yd³, and damp moisture factor is 1.15. So weight = 1.185 × 2,000 × 1.15 ≈ 2,726 lb, or about 1.36 US tons. A half-ton pickup with a 1,500 lb payload would need two trips.
Alternative formulas
Metric form: Weight_kg = Volume_m³ × Density_kg/m³ × MoistureFactor
When to use: When working with metric suppliers or international landscaping specs. 1 lb/yd³ ≈ 0.5933 kg/m³.
Direct ton estimate: Tons ≈ Volume_yd³ × 1.0 (for typical damp topsoil)
When to use: Quick mental math for damp topsoil only. Inaccurate for mulch, sand, or saturated clay — use the full formula for those.
Parameter explanations
| Input | Unit | What it means | Impact on results |
|---|---|---|---|
| Soil type | — | The mineral and organic composition of what you're hauling — topsoil, fill, clay, sand, compost, mulch, etc. | Largest single driver. Switching from mulch (600 lb/yd³) to mason sand (2,700 lb/yd³) is a 4.5x weight change for the same volume. |
| Moisture level | — | How wet the soil is at the moment you're loading it, from kiln-dry to standing-water saturated. | Multiplies weight by 1.00 to 1.50. Wet weather alone can add 30–50% to the load you expected. |
| Volume | yd³, ft³, m³, or gallons | The quantity of soil being weighed, in your chosen unit. Internally converted to cubic yards. | Linear — doubling volume doubles weight. The only number where unit confusion causes catastrophic errors (cubic feet vs cubic yards is a 27x mistake). |
| Volume unit | — | The unit your volume number is expressed in. The calculator converts everything to cubic yards before computing weight. | Doesn't change real weight, only the interpretation of your input. Wrong selection here causes the most common user error. |
| Display weight in | — | The unit you want the final weight shown in: lb, US tons, kg, or metric tonnes. | Cosmetic only — internal math is in pounds. 1 US ton = 2,000 lb; 1 metric tonne = 2,205 lb. |
| Vehicle payload capacity | lb | The maximum cargo weight your vehicle is rated for, found on the door-jamb sticker. | Used to calculate how many trips you need and whether a single load would overload your vehicle. Does not affect total soil weight. |
Assumptions
Dry bulk densities are landscape-industry averages; actual material from your specific supplier may vary ±10%.
Moisture multipliers are simplified bands, not continuous measurements. — Real soil moisture is a continuum from 0% to ~50% water by weight. The four bands (dry/damp/wet/saturated) approximate the visual cues most people can judge by sight and touch.
The seed-key example of 'a yard of soil' is only a default — the calculator works for any volume. — We default to 1 cubic yard because it's the most-searched quantity, but you can enter 0.1 to 100 in any supported volume unit.
Volume conversions use exact factors: 1 yd³ = 27 ft³ = 0.7646 m³ ≈ 201.97 US gallons.
Payload comparison uses the entered vehicle rating as-is; we do not subtract for driver, passengers, fuel, or accessories — you should subtract those yourself.
How to use this calculator
- Pick the soil type that matches your purchase — Match the label on the supplier's bin or invoice. 'Garden soil' at retail is usually closer to compost than to topsoil.
- Set moisture based on recent weather — If it rained in the last 24 hours or the pile is steaming, choose 'wet' or 'saturated'. When in doubt, choose one level wetter than you think.
- Enter volume in the unit your supplier uses — Bulk yards usually sell in cubic yards; bagged products are in cubic feet. Double-check the volume unit dropdown before clicking calculate.
- Enter your vehicle's payload (optional but recommended) — Find it on the yellow sticker inside the driver door. The calculator will tell you how many trips you actually need and flag overloads.
- Add a 10% safety margin if you're near payload — Real-world soil density varies; mentally pad the result before deciding whether to take one trip or two.
