Ordering dirt for a garden bed, a lawn regrade, or a foundation backfill starts with one question: how much do you need, and what will it weigh? Suppliers quote dirt in cubic yards, and the numbers you hear back depend on the volume of the space you are filling, the type of material, and how much moisture it holds. Weight drives trucking costs, delivery charges, and whether your own truck can carry the load. Before you place an order, the practical breakdown of topsoil costs, coverage, and volume math shows how the same figures play out in real purchases, and the sections below walk through the weights, prices, and calculations you will actually use.
How Much Does a Yard of Dirt Weigh?
A cubic yard of dirt is a cube that measures 3 feet on each side, which works out to 27 cubic feet. The weight of that cube ranges from roughly 2,000 to 3,000 pounds depending on the composition and moisture content of the soil. A ton of dirt weighs 2,000 pounds, so a single dry yard of topsoil lands right around one ton, while wet or sandy loads run heavier.
Different types of dirt sit at different points on that scale. Construction fill runs heavier than loose garden soil, dry sandy material is the heaviest of the common types, and clay soil is lighter than many people expect because its weight depends on how much air the soil structure holds.
Where the one ton figure comes from
The default assumption that a yard of dirt weighs one ton comes straight from the definition of a ton: 2,000 pounds. Suppliers and trucking companies use that figure for quick estimates, and it is accurate enough for dry topsoil. The trouble starts when the same estimate is applied to wet or sandy material, because those loads can exceed a ton by 25 to 50 percent.
Typical weights by soil type
- Loose dry topsoil: 2,000 to 2,200 pounds per yard, about one ton
- Construction fill dirt: around 2,150 pounds per yard
- Clay soil: around 1,700 pounds per yard
- Dry sandy soil: up to 2,600 pounds per yard
- Wet topsoil: 2,500 to 3,000 pounds per yard
If the dirt is heading to a front yard where you plan to remove the grass, keep the soil type in mind before you order. The practical alternatives for a beautiful lawn-free yard usually call for different soil depths than a turf lawn, and the depth you choose changes both the volume and the weight you pay to have delivered.
Wet vs Dry and Heavy vs Light Dirt
Moisture is the single biggest variable in dirt weight. Dry topsoil weighs around 2,000 pounds per cubic yard, and the same yard can gain several hundred pounds after a rain. A load that sits uncovered on a delivery truck picks up moisture, and a load ordered after a wet week arrives heavier than the estimate you planned around. Ordering early in the day and checking the forecast matters more than most buyers realize.
How moisture changes the math
Water adds weight without adding volume, which means the same cubic yard can sit at either end of the 2,000 to 3,000 pound range depending on when it is dug and how it is stored. For projects where the dirt is weighed on a scale, such as landfill cover or trucked fill, wet material costs more per load even when the price per yard looks the same.
A density comparison across materials
Soil sits on the heavy end of the building material scale. Insulation sits at the opposite extreme, which is why the calculations for how much insulation you need look nothing like the cubic yard math for dirt. Density tables are material specific, and mixing them up produces estimates that are off by a factor of ten or more.
| Material | Approximate weight per cubic yard |
|---|---|
| Dry topsoil | 2,000 to 2,200 lbs |
| Wet topsoil | 2,500 to 3,000 lbs |
| Sand | 2,700 to 3,200 lbs |
| Gravel | 2,800 to 3,400 lbs |
| Mulch | 400 to 800 lbs |
| Ready-mix concrete | about 4,000 lbs |
Mulch is the useful contrast for landscaping work: a yard of mulch weighs a fraction of a yard of dirt, so the same truck that carries one yard of wet topsoil can haul three or four yards of mulch.
How Many Cubic Yards of Dirt Do I Need?
Every dirt order starts with the same formula: length times width times depth, converted into cubic yards. One cubic yard equals 27 cubic feet, so the formula is length in feet times width in feet times depth in feet, divided by 27, equals cubic yards.
- Measure the length and width of the area in feet.
- Convert the depth you need from inches to feet by dividing by 12.
- Multiply length x width x depth to get the volume in cubic feet.
- Divide the result by 27 to get cubic yards.
- Add 5 to 10 percent for settling and compaction.
A planting bed that is 10 feet long and 4 feet wide, filled 6 inches deep, works out to 10 x 4 x 0.5, which is 20 cubic feet, or about 0.74 cubic yards. Round up to a full yard when you order, because soil settles after it is spread and watered.
Coverage at common depths
One cubic yard covers a fixed area at each depth, and these figures let you check a supplier quote in seconds.
Coverage per cubic yard
| Depth | Area covered by 1 cubic yard |
|---|---|
| 2 inches | 162 square feet |
| 3 inches | 108 square feet |
| 4 inches | 81 square feet |
| 6 inches | 54 square feet |
| 12 inches | 27 square feet |
Bulk topsoil, sand, and gravel are stocked by garden centers and lumber yards that also run building material operations, and the yard layout at these facilities determines how orders are staged and loaded for delivery.
How Much Does a Yard of Dirt Cost?
Dirt prices vary by region, season, and material quality, but the ranges below cover what most homeowners pay. Fill dirt is the cheapest product, screened topsoil sits in the middle, and premium blended soils run highest. Buying from local suppliers keeps hauling costs down, because the delivery fee often rivals the material price on small orders.
Typical prices per cubic yard
| Product | Price per cubic yard |
|---|---|
| Fill dirt | $5 to $15 |
| Screened topsoil | $12 to $35 |
| Premium blended soil | $20 to $55 |
| Sand | $15 to $40 |
| Delivery fee | $50 to $150 |
Prices also shift with the season. Spring demand pushes topsoil prices up in many markets, while late fall often brings discounts as suppliers clear inventory before winter.
Ways to cut the cost of a dirt order
- Buy from a supplier within a short drive of the job site
- Order the largest quantity you can store, since per yard prices drop with volume
- Pick up with your own truck and trailer instead of paying delivery
- Compare screened and unscreened material, since unscreened fill is much cheaper for grading
- Ask about clean fill from local excavation jobs, which is often free or low cost
Around the house, fresh topsoil is the backbone of most planting projects, and the low-maintenance front yard landscaping design ideas that cut yard work usually start with a few inches of amended soil spread over the planting area.
Can a Yard of Dirt Fit in a Pickup Truck?
A yard of dirt fits in most full-size pickup beds by volume, but volume is not the limiting factor. A standard 6 foot bed with 18 inch sides holds about 1.3 cubic yards, which is more than enough room for a single yard. Weight is the real constraint: a yard of dry topsoil weighs around a ton, and a yard of wet topsoil can weigh 2,500 to 3,000 pounds. Many half-ton pickups carry a payload rating between 1,000 and 1,500 pounds, which means one wet yard exceeds the safe limit.
Volume versus payload
Check the payload rating on the driver side door sticker before you load. The rating covers the truck, the passengers, and the cargo together, so a full cab of passengers leaves even less room for dirt. Keep the load centered over the rear axle and cover it with a tarp before driving.
Hauling checklist
- Confirm the payload rating on the door sticker
- Ask the supplier whether the load is wet or dry
- Keep the pile centered over the rear axle
- Cover the load with a tarp before driving
- Plan a route that avoids steep hills and soft shoulders
The same weight and volume discipline applies to winter materials. Spreading deicing salt on driveways and walkways is a common task where over-ordering is easy, and knowing how much deicing salt is too much keeps both your concrete and your budget intact.
Use the Cubic Yard Formula for Every Bulk Material
The formula that sizes a dirt order works for every bulk material sold by the yard. Gravel, sand, crushed stone, and mulch all use the same length x width x depth calculation, and only the weight per yard changes. Keeping one formula in mind means you can estimate any project without waiting for a quote.
Weights for other bulk materials
- Sand: 2,700 to 3,200 pounds per yard
- Gravel: 2,800 to 3,400 pounds per yard
- Crushed stone: 3,000 to 3,400 pounds per yard
- Mulch: 400 to 800 pounds per yard
Confirm the numbers with your supplier
Every supplier has slightly different density figures for the same material name, so confirm the weight per yard before you commit to a truck size or delivery schedule. The load ticket that comes with your delivery lists the exact weight, which is worth keeping for your records.
For crushed stone projects, the step-by-step example of how much crushed stone you need walks through the cubic yard formula with worked numbers, and the same process transfers directly to dirt, sand, and gravel.
