A cubic yard of dirt weighs between 1,200 and 2,800 pounds, depending on whether it’s fill dirt, topsoil, or screened clean dirt — and on how moist it is. Fill dirt (the unprocessed material under topsoil) averages around 2,000 lbs per cubic yard. Below: exact weights by dirt type, what differentiates dirt from topsoil, and how to calculate the weight of your specific load.
How much does a yard of dirt weigh?
Here are the weight ranges by dirt type:
| Dirt Type | Weight per Cubic Yard | Notes |
|---|---|---|
| Fill dirt (dry) | 1,800 – 2,000 lbs | The most common “dirt” — excavated subsoil |
| Fill dirt (wet) | 2,200 – 2,800 lbs | After rain or in clay-heavy soils |
| Topsoil | 1,500 – 3,000 lbs | See topsoil weight guide for full detail |
| Clean dirt (screened, no rock) | 1,800 – 2,200 lbs | Higher quality, used for grading |
| Loam dirt | 2,000 – 2,300 lbs | Higher organic content |
| Clay dirt | 2,400 – 2,800 lbs | Heaviest, holds water |
The wide range comes from three factors: moisture content (water alone adds 20-30% to weight), clay content (clay particles pack tightly and are heavy), and what’s mixed in (rocks, organic matter, or contaminants).
Dirt vs topsoil — what’s the difference?
Searches for “dirt weight” often confuse two different materials. Here’s the distinction:
Dirt is a generic term for soil or earth, often used loosely. In landscaping, it usually refers to subsoil — the layer beneath topsoil. It lacks organic matter and isn’t ideal for growing plants.
Fill dirt specifically means subsoil material excavated and used for grading, filling holes, or building up land. It’s the cheapest soil product and isn’t intended for planting.
Topsoil is the nutrient-rich upper 2-12 inches of natural soil. It contains organic matter, microorganisms, and the nutrients plants need. Topsoil is screened (filtered to remove rocks and debris) before being sold.
Soil profile structure, from top to bottom:
- O horizon: surface organic matter (leaves, decaying material)
- A horizon (topsoil): 2-12 inches deep, rich in nutrients and organic matter
- B horizon (subsoil): where fill dirt typically comes from — minerals leached down from above, less organic matter
- C horizon: weathered parent rock, mostly minerals
When someone searches “how much does a yard of dirt weigh,” they usually mean fill dirt or general subsoil — not topsoil. If you’re buying material for a garden or lawn, you want topsoil. If you’re filling a hole or grading a slope, you want fill dirt. For a complete breakdown of when to use each material and how to layer them on real projects, see our fill dirt vs topsoil comparison guide.
Weight of fill dirt
Fill dirt is the most common search intent under “dirt weight.” A cubic yard of dry fill dirt weighs about 2,000 pounds. Wet fill dirt — common after rain or in clay-heavy regions — can weigh 2,800 pounds or more.
Builders and landscapers buy fill dirt for these reasons:
- Grading slopes — building up low spots or reshaping terrain before final landscaping
- Filling depressions — leveling out a yard with low spots or old swimming pool footprints
- Backfilling foundations — replacing excavated material around new construction
- Raising garden beds — though topsoil is layered on top for the planting zone
Fill dirt typically costs $5-15 per cubic yard delivered — significantly cheaper than topsoil ($20-50/yd) because it doesn’t require screening or quality control.
How to calculate dirt weight for your project
Use this two-step formula to calculate the weight of any dirt volume:
Step 1: Calculate volume in cubic yards
Volume (yd³) = (Length × Width × Depth) ÷ 27Length, Width, and Depth all in feet. 27 cubic feet equals 1 cubic yard.
Step 2: Multiply by weight per yard
Weight (lbs) = Volume (yd³) × Weight per yd³Worked example: filling a depression in the yard
- Depression dimensions: 6 ft long × 6 ft wide × 2 ft deep
- Volume: (6 × 6 × 2) ÷ 27 = 2.67 cubic yards
- Weight (dry fill dirt): 2.67 × 2,000 = 5,340 pounds
That’s the weight of dirt you’d need to fill that depression — over 5,000 lbs, which is more than any half-ton pickup can safely haul in one trip.
Truck capacity for hauling dirt
Knowing weight per yard tells you what your vehicle can handle:
| Vehicle | Typical Dirt Capacity |
|---|---|
| Half-ton pickup (e.g., F-150, Silverado 1500) | 0.5 yd³ max safely |
| 3/4-ton pickup (e.g., F-250, Silverado 2500) | 1 yd³ |
| 1-ton pickup (e.g., F-350, Silverado 3500) | 1.5 yd³ |
| Small dump truck | 5 – 10 yd³ |
| Tri-axle dump truck | 15 – 20 yd³ |
Critical safety note: “max capacity” doesn’t always equal “safe capacity.” Check your specific truck’s payload sticker on the driver-side door jamb. Overloading a pickup can damage the suspension, frame, and tires — and can cause loss of control on the road. For loads larger than your truck can handle, hire delivery.

Frequently asked questions
What does 1 yard of dirt look like?
One cubic yard of dirt forms a pile roughly 3 feet wide × 3 feet deep × 3 feet tall when freshly dumped. It fills a standard pickup truck bed approximately to the top rail. Spread out, it covers 100 square feet at 3 inches deep, or 50 square feet at 6 inches deep.
How much does 5 yards of dirt weigh?
Five cubic yards of dirt weighs approximately 6,000-11,000 lbs depending on dirt type and moisture. That’s a small-dump-truck-sized load. Most consumer pickups cannot haul 5 yards safely or legally.
Is dirt heavier than topsoil?
Fill dirt is slightly heavier than typical topsoil on average — fill dirt averages ~2,000 lbs/yd while topsoil averages ~2,000-2,400 lbs/yd. Clay-heavy dirt can be much heavier than topsoil (2,400-2,800 lbs/yd). Compost-rich topsoil is the lightest at ~1,500-1,800 lbs/yd.
How much does a dump truck of dirt weigh?
A small dump truck holds 5 cubic yards of dirt, weighing 9,000-14,000 lbs. A tri-axle dump truck holds 15-20 cubic yards, weighing 27,000-56,000 lbs. Highway weight regulations limit how much a dump truck can legally carry.
Why is fill dirt cheaper than topsoil?
Fill dirt is excavated subsoil that hasn’t been screened, amended, or quality-checked. Topsoil requires screening to remove rocks and debris, may be amended with compost, and represents the more valuable upper soil layer. Fill dirt is essentially a byproduct of excavation work — sometimes given away free.
Where can I buy fill dirt near me?
Many topsoil suppliers also sell fill dirt. Excavation companies and construction sites often have fill dirt available — sometimes for free if you can haul it yourself. Topsoil.com lists local soil suppliers across the US who can quote both topsoil and fill dirt.
