It depends on the depth you need. For a 10×10 foot area (100 sq ft) at a 4-inch depth  suitable for lawn seeding  you need (10 × 10 × 0.333) ÷ 27 = approximately 1.23 cubic yards. At 6 inches deep, that rises to 1.85 cubic yards. At 1 inch (light topdressing), you'd need just 0.31 cubic yards  around 8.3 cubic feet, or roughly 11 standard 0.75 cu ft bags. Use the calculator above and enter your actual depth for a precise result.

For a new lawn seeded from scratch, aim for 4 to 6 inches of topsoil. This depth gives grass roots enough fertile soil to establish before hitting lower-quality subsoil. Anything less than 3 inches will produce a lawn that struggles in dry weather and looks stressed during summer. If you're overseeding an existing lawn or topdressing bare patches, 1 to 2 inches is generally sufficient. For sod installation, 4 to 6 inches is ideal  sod needs a firm, nutritious base to root within the first few weeks after laying.

One cubic yard equals 27 cubic feet. The number of bags depends on the bag size: 0.75 cu ft bags require 36 bags, 1 cu ft bags require 27 bags, and the larger 1.5 cu ft bags require 18 bags to fill one cubic yard. For any project exceeding 0.5 cubic yards, buying in bulk is almost always more economical. At typical retail prices, bagged topsoil can cost 3 to 5 times more per cubic foot than bulk delivery once you factor in the convenience premium. Our calculator shows both cubic yards and bag count so you can compare options instantly.

A cubic yard of topsoil typically weighs between 1,800 and 2,200 pounds, with the average around 2,000 lbs (roughly one ton). Moisture content is the biggest variable  a cubic yard of saturated topsoil can weigh significantly more than dry topsoil. This matters enormously for transport planning. A standard half-ton pickup truck has a payload capacity of around 1,000–1,500 lbs, meaning it can safely carry approximately 0.5 to 0.75 cubic yards. Overloading damages your suspension and is a safety hazard. For anything over 1 cubic yard, arrange for professional delivery.

Yes, in thin layers  this is called topdressing. Applying 0.5 to 1 inch of topsoil over existing lawn can improve soil structure, fill low spots, and encourage denser growth. However, if you apply more than 1 to 1.5 inches at once, you risk smothering the grass and killing it. For a major lawn renovation where you want to add 4+ inches of new topsoil, it's better to scalp the existing grass first, till the ground, and then apply your new topsoil layer before reseeding or laying sod. Never dump several inches of topsoil over a healthy lawn and expect it to survive.

Topsoil is natural soil taken from the upper layer of the ground  it's your general-purpose landscaping material used for filling, grading, and establishing lawns. Garden soil is a premium blend that combines topsoil with compost, peat moss, or other organic amendments. Garden soil has a higher nutrient content and better moisture retention, making it ideal for vegetable beds and flower borders. It's also more expensive and not practical for large fill volumes. For raised beds or containers, garden soil or a custom mix is the better choice. For large lawn areas, screened topsoil is more cost-effective.

Spring and early fall are the best times to add topsoil, for different reasons. Spring applications benefit from warming temperatures and natural rainfall, giving seeds or transplants the best start. Fall is excellent for lawn topdressing  cool temperatures reduce transplant stress, and rain helps topsoil settle and integrate before winter. Avoid adding topsoil in the height of summer heat, as it can dry out rapidly before plants establish. In winter, frozen ground makes spreading difficult and the material won't integrate properly until the soil thaws. For vegetable gardens, adding topsoil in fall and letting it rest over winter is ideal  it gives organic matter time to break down.

Bulk topsoil typically costs to per cubic yard depending on type and your location, with screened topsoil averaging – per cubic yard before delivery. Delivery charges vary widely  expect –0 for a standard truckload depending on distance. Premium garden mix or organic-enriched topsoil can run –0 per cubic yard. Bagged topsoil at garden centers costs – per bag, which translates to roughly 5–0 per cubic yard  three to five times the cost of bulk. Always get at least two quotes from local suppliers. Prices vary significantly by region and season, with spring prices often higher due to demand.
