Compact Soil / Clay – ~3,000 lbs/yd³
Topsoil & Compost Mix – ~2,700 lbs/yd³
Sandy Loam – ~2,200 lbs/yd³
Different soil compositions have different densities.

Calculation Logic: We calculate volume in cubic feet (L × W × D), convert to cubic yards (÷ 27), multiply by the specific soil density to get total pounds, and finally divide by 2,000 to get Tons.

What is How to Calculate Weight of Top Soil?
Understanding how to calculate weight of top soil is a fundamental step in construction, landscaping, and gardening projects. While volume (measured in cubic yards) tells you how much space the soil will fill, weight (measured in tons) dictates the logistics of transport, the type of truck needed, and often the final cost of the material.
Many homeowners make the mistake of ordering soil purely by volume without realizing that wet topsoil can weigh significantly more than dry topsoil. This oversight can lead to overloaded trailers, broken suspension, or unexpected delivery surcharges. This tool allows professionals and DIY enthusiasts to estimate the tonnage required accurately.
Top Soil Weight Formula and Mathematical Explanation
To calculate weight of top soil, we must first determine the volume of the area and then apply the density factor of the specific soil type. The math involves three distinct steps: finding cubic feet, converting to cubic yards, and then calculating tonnage.
The Core Formula:
Weight (Tons) = (Volume in Cubic Yards × Density in lbs/yd³) ÷ 2,000
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Length (L) | Distance of the area | Feet | Any |
| Width (W) | Breadth of the area | Feet | Any |
| Depth (D) | Thickness of soil layer | Inches | 2″ – 12″ |
| Density | Weight per unit volume | lbs/yd³ | 2,000 – 3,000 |
Practical Examples (Real-World Use Cases)
Example 1: The Raised Garden Bed
A gardener wants to fill a raised bed that is 8 feet long, 4 feet wide, and 12 inches deep with standard moist topsoil.
- Volume (cu ft): 8 × 4 × (12/12) = 32 cubic feet.
- Volume (cu yds): 32 ÷ 27 ≈ 1.19 cubic yards.
- Weight: 1.19 yds × 2,500 lbs/yd = 2,975 lbs.
- Final Tonnage: 2,975 ÷ 2,000 = 1.49 Tons.
- Financial Impact: At $40/ton, this project costs roughly $59.60 in material.
Example 2: The Front Lawn Leveling
A homeowner needs to level a depression in their lawn. The area is roughly 20 feet by 20 feet, requiring an average depth of 3 inches. They are using a sandy loam mix.
- Volume (cu ft): 20 × 20 × (3/12) = 100 cubic feet.
- Volume (cu yds): 100 ÷ 27 ≈ 3.70 cubic yards.
- Weight: 3.70 yds × 2,200 lbs/yd (lighter density) = 8,140 lbs.
- Final Tonnage: 8,140 ÷ 2,000 = 4.07 Tons.
- Logistics: This weight exceeds the payload of most pickup trucks (usually 0.5 to 1 ton), requiring a dump truck delivery.
How to Use This Top Soil Calculator
- Measure Dimensions: Measure the length and width of your project area in feet.
- Determine Depth: Decide how deep the soil needs to be. For new lawns, 4-6 inches is standard; for top-dressing, 0.5-1 inch is common.
- Select Soil Type: Choose the soil type from the dropdown. If you are unsure, "Standard Topsoil (Moist)" is the safest bet for weight estimation.
- Enter Price (Optional): If you know the price per ton from your local supplier, enter it to get a cost estimate.
- Review Results: The calculator will display the total tons needed. Use the "Copy Estimation" button to save these numbers for your supplier.
Key Factors That Affect Soil Weight Results
When you calculate weight of top soil, several physical and financial factors can alter the final numbers:
- Moisture Content: Water is heavy. Soil that has been sitting in the rain can weigh 20-30% more than dry soil. A cubic yard of dry topsoil might weigh 2,000 lbs, while the same volume saturated could weigh 2,700 lbs.
- Compaction: Loose soil fluffs up and takes up more space. Once installed and compacted (stepped on or rolled), the volume decreases, effectively increasing the density per cubic foot required to fill the original space.
- Composition: Soil with high sand content is generally heavier than soil with high organic matter (compost) content. Rock and gravel mixed in will drastically increase the weight.
- Buy-in-Bulk vs. Bagged: Bagged soil is often sold by volume (cubic feet) rather than weight, whereas bulk soil at landscape supply yards is almost always sold by the ton.
- Delivery Fees: The weight of the soil determines the size of the truck needed. Exceeding a truck's weight limit will require a second trip, doubling your delivery fee.
- Wastage Factor: It is standard practice to order 5-10% more material than calculated to account for spillages, uneven subgrade, and compaction during installation.
Frequently Asked Questions (FAQ)
Q: How many cubic yards are in a ton of topsoil?
A: It depends on density, but typically 1 ton of standard topsoil equals approximately 0.7 to 0.8 cubic yards. Conversely, 1 cubic yard weighs about 1.2 to 1.4 tons.
Q: Should I buy soil by the ton or by the yard?
A: Most bulk suppliers sell by the ton because they weigh the truck before and after loading. Knowing how to calculate weight of top soil ensures you convert your required volume (yards) into the billing unit (tons) correctly.
Q: Can I pick up 1 yard of soil in my pickup truck?
A: Likely not. A full cubic yard of topsoil weighs about 2,500 lbs. A standard half-ton pickup has a payload capacity of roughly 1,000-1,500 lbs. You would need a heavy-duty (1-ton) truck or a trailer.
Q: Does wet soil cost more?
A: If you are paying by the ton, yes. You are paying for the water weight. It is financially advantageous to buy soil during dry spells if possible.
Q: How deep should topsoil be for grass?
A: For a new lawn, a depth of 4 to 6 inches is recommended to encourage healthy root growth.
Q: What is the difference between topsoil and garden soil?
A: Topsoil is the upper layer of earth, often screened for rocks. Garden soil is usually topsoil enriched with compost and organic matter, making it lighter and more nutrient-rich.
Q: How do I measure an irregularly shaped area?
A: Break the area down into smaller rectangles or squares, calculate the volume for each, and add them together.
Q: What is the density of clay vs. sandy soil?
A: Clay is dense and heavy (approx 2,700-3,000 lbs/yd³ when wet), while sandy soil is also heavy due to silica (approx 2,600 lbs/yd³). Soil with high organic matter is lighter (1,500-2,000 lbs/yd³).
