Depth moves a topsoil order more than area does. The same 1,000-square-foot lawn needs 12 cubic yards at a 4-inch depth and barely 1.5 yards as a half-inch topdressing. So before anything else, decide what the topsoil is for. This topsoil calculator converts your area and chosen depth into cubic yards (the unit topsoil sells in) and tons, at about 2,200 lb per dry yard. Screened topsoil, which is what we stock, has had rock, roots and clods sifted out; that difference is hours of raking you won't do.

Depth first, then the math

  • Topdressing a lawn: 1/4 to 1/2 inch, raked in so grass tips stay visible.
  • Overseeding prep: 1/2 to 1 inch.
  • New lawn from seed or sod: 4–6 inches over loosened subgrade.
  • Flower beds: 6 inches, worked into the native soil below.
  • Raised vegetable beds: 12 inches, though a garden-soil blend serves beds better (that's the Soil Calculator).
  1. Measure the area in feet and pick the depth from the list above.
  2. Cubic feet ÷ 27 = cubic yards; yards × 1.1 = tons. The calculator does both and adds 5% if you keep the allowance on.
Cubic yards = (Area sq ft × Depth in ÷ 12) ÷ 27
Tons = cubic yards × 1.1

Worked example: 1,000 square feet of new lawn

At 4 inches: 1,000 x 0.333 = 333 cubic feet = 12.3 cubic yards, around 13.5 tons on the truck. Sod crews in our delivery data order this as 12.5 to 13 yards and spread the difference into edges and low corners. If the subgrade also needs building up, do that part with fill dirt first and spend the topsoil budget only on the top 4 inches where roots live.

What screened topsoil is (and how to judge a load)

Topsoil is the upper layer of natural soil, alive with organic matter. Screening passes it over a mesh that pulls out stones, roots and clods. Good screened topsoil is dark, crumbles in your hand, and smells like a forest floor rather than a swamp. Squeeze a moist handful: it should ball up loosely and break apart with a poke. A slick ribbon means heavy clay; refusal to ball at all means it's mostly sand. Gray color or a sour smell means it was stored wet and airless, and visible rhizomes mean you're importing weeds. Photograph anything that looks off before spreading and call us; that's what makes it fixable.

Spreading without regrets

  • Loosen the subgrade an inch before spreading. Four inches of topsoil over sealed clay drains like a bathtub with the plug in.
  • Grade away from the house: a 6-inch fall over the first 10 feet.
  • Firm, don't stomp. A footprint should sink about half an inch in properly settled topsoil.
  • Schedule delivery for the week you'll spread. A rained-on pile weighs a third more per shovel and smears instead of raking.

Topsoil orders, explained

How much topsoil do I need for a new lawn?
Plan 4–6 inches: 1.25 to 1.85 cubic yards per 100 square feet. A 1,000-square-foot lawn lands between 12 and 18 yards; the calculator pins your exact figure.
How much does a yard of topsoil weigh?
About 2,200 lb dry, 1.1 tons. Soaked, the same yard can pass 2,700 lb. You buy volume, so weather changes nothing about how far it spreads.
How much is a yard of topsoil?
The current per-yard price is on our Top Soil product page, delivery included. For scale, one bulk yard replaces about 36 bags at 40 lb each, so compare a delivered yard against the shelf price of 36 bags and decide once.
How much does a yard of topsoil cover?
108 square feet at 3 inches, 81 square feet at 4 inches, 54 square feet at 6 inches. As a half-inch topdressing it stretches to 648 square feet.
What is topsoil?
The top layer of natural soil, roughly the first 5–12 inches, where organic matter and soil life concentrate. It's screened before sale to remove rock and debris. Below it sits subsoil, sold as fill dirt for structural work.
Can I put topsoil over existing grass?
Only as a thin topdressing up to a half inch, which grass grows through. To raise grade more than an inch, strip or kill the turf first. Buried sod rots unevenly and telegraphs lumps into the new lawn for a year.
Topsoil or garden soil for beds?
Beds do better with garden soil, which is topsoil blended with compost. Lawns and grading want straight screened topsoil. The Soil Calculator covers the blended products and raised-bed math.
Do I need to till before adding topsoil?
Scratch the existing surface an inch deep at minimum. It keys the layers together so water and roots cross the boundary instead of stopping at it.
