Calculate topsoil volume in cubic yards and tons for gardens, lawns, and raised beds. Enter area and depth to get accurate material estimates.
Topsoil is the foundation of any successful landscaping, gardening, or lawn renovation project. This nutrient-rich upper layer of soil is what plants actually grow in, and getting the right amount is essential. Too little and your plants will struggle; too much and you've wasted money and changed your grades.
This calculator takes your project area and desired topsoil depth, then tells you exactly how many cubic yards and tons to order. Topsoil typically weighs 1.0 to 1.3 tons per cubic yard depending on moisture and composition. Screened topsoil is lighter and fluffier, while unscreened topsoil is denser and less uniform.
Whether you're building garden beds, establishing a new lawn, topdressing an existing yard, or filling raised planters, having an accurate material estimate saves time, money, and multiple trips to the landscape supply yard.
Precise calculations are essential for meeting regulatory requirements, passing inspections, and ensuring the long-term structural integrity and safety of the completed project.
Topsoil is sold by the cubic yard (bulk delivery) or by the bag at retail. Bulk is far cheaper per unit, but you need to know how much to order. This calculator eliminates guesswork and helps you compare bulk vs. bagged prices so you pick the most cost-effective option for your project size.
Volume (ft³) = Area (ft²) × Depth (in) ÷ 12 Volume (yd³) = Volume (ft³) ÷ 27 Weight (tons) = Volume (yd³) × Density (tons/yd³) Bags (40 lb) = Weight (lbs) ÷ 40
Result: 24.69 CY / 27.16 tons
A 2,000 sq ft lawn at 4 inches of topsoil needs 666.67 ft³, which is 24.69 yd³. At 1.1 tons per cubic yard, that's 27.16 tons — about 2 large dump truck loads. Buying this in 40-lb bags would require over 1,300 bags, making bulk delivery the clear choice.
The formula is simple: multiply area in square feet by depth in feet, then divide by 27 to convert to cubic yards. The key is choosing the right depth for your application. Lawns need 4–6 inches, gardens 6–12 inches, and topdressing just 1–2 inches.
For projects under 2 cubic yards, bagged topsoil from a home center may be convenient. For larger projects, bulk delivery saves 60–80% per yard. Most landscape suppliers deliver by the truck load (10–16 CY per load).
Good topsoil is dark, crumbly, and free of debris, large rocks, and weed seeds. Screened topsoil has been processed to remove lumps and is easier to spread. Ask your supplier about organic content and pH levels if you're planting sensitive species.
Spread topsoil evenly using a landscaping rake. Use a roller to lightly compact the surface for lawns. Ensure the final grade slopes away from buildings at a minimum of 1–2% for drainage. Water the topsoil lightly before seeding or sodding to help it settle into the subgrade.
A new lawn needs 4–6 inches of topsoil for healthy root development. For overseeding or topdressing, 1–2 inches is sufficient. Garden beds benefit from 6–12 inches of quality topsoil.
Topsoil typically weighs 1.0–1.3 tons (2,000–2,600 lbs) per cubic yard. Dry screened topsoil is closer to 1.0 ton, while wet or unscreened topsoil can be 1.3+ tons per yard.
Topsoil is the natural top layer of earth, screened to remove debris. Garden soil (or planting mix) is topsoil blended with compost, peat, and other amendments for better drainage and nutrient content. Garden soil costs more but performs better for planting.
Bulk topsoil costs $15–$50 per cubic yard depending on quality and location. Screened topsoil is $25–$50/yd³, while unscreened is $15–$30/yd³. Delivery typically adds $50–$100 per trip.
It takes roughly 36 bags (40 lbs each) or 27 bags (1 cubic foot each) to equal one cubic yard. Bulk delivery is far more economical for anything over 2–3 cubic yards.
You can topdress existing grass with up to 1 inch of topsoil at a time. Thicker layers will smother the grass. For deeper application, remove or till the existing turf first.
Yes, freshly spread topsoil typically settles 10–20% over the first few weeks, especially after watering and rain. Order extra to compensate, particularly for areas that need a precise final grade.
Spring and early fall are ideal for adding topsoil. Avoid spreading during heavy rain or extreme heat. For new lawns, time your topsoil delivery with your planned seeding or sodding date.
