How much topsoil for a new 1,000 sq ft lawn?
Four inches of firmed topsoil over a new 1,000 sq ft lawn is 12.3 cubic yards in place. With 20% for settling, order about 14.8 cubic yards (400 cubic feet), which weighs roughly 17.8 tons at average moisture; a yard selling in half-yard steps will round it to 15 cubic yards.
How to work it out
- Area: 1,000 sq ft
- 1,000 sq ft × 4 in ÷ 12 = 333 cu ft ÷ 27 = 12.3 cu yd
- 12.3 cu yd + 20% for settling = 14.8 cu yd
- 14.8 cu yd × 1.2 tons/cu yd ≈ 17.8 tons
- Bulk: 14.8 cu yd rounded up to the next ½ cu yd = 15 cu yd
Penn State Extension’s lawn-establishment guide asks for a minimum of 4 to 6 inches of good topsoil under new turf, measured after it has been firmed. Loose soil straight off the truck settles, which is why this page adds 20%: spread about 4.8 inches loose to end up with 4 inches once it is rolled and watered. If your ground was scraped bare by construction, lean toward the deeper end of that range.

- That many bags is a lot of carrying. Bulk topsoil is usually far cheaper at this volume — ask about delivery and whether it is screened.
- Hauling it yourself? At roughly 1,500 lb per load — a typical half-ton pickup payload; check the sticker in your door jamb — that is about 24 trips. Soil fills the payload long before it fills the bed.
- Spread it about 20% deeper than the finished depth: 4 in firmed is about 4.8 in loose. Water or roll it, then fill any dips before seeding.
Weight of 1,000 sq ft of topsoil 4 in deep, by moisture

|---|---|---|
| Dry, loose topsoil | 14.8 cu yd | 14.8 tons |
| Topsoil, average moisture | 14.8 cu yd | 17.8 tons |
| Wet topsoil | 14.8 cu yd | 20.7 tons |
What to know about topsoil for a 1,000 sq ft lawn
Fifteen yards is a truck delivery, not a trailer job. At close to eighteen tons it is more than one load for a small single-axle truck (the calculator’s default shows three), while a bigger tri-axle may bring it in one, so ask the supplier and tell them where it can be tipped: a pile this size covers a good part of a driveway, and that weight can crack thin asphalt or pavers. Put a tarp down if it has to sit on a lawn you want to keep.
Moving it is most of the work. A wheelbarrow carrying 5–6 cubic feet at a time needs something like 65–80 trips to shift 400 cubic feet, which is a long weekend for two people. On an open site, renting a compact loader for a day is often worth pricing.
Don’t just lay the new soil on top of hard subsoil. Penn State suggests working about 2 inches of the topsoil into the top 2–3 inches of the ground below, so roots and water don’t stall at a sharp boundary. Rough-grade so water runs away from the house, roll it lightly, then rake out the high and low spots before seeding.
If you plan to lay sod rather than seed, finish the soil roughly the thickness of the sod below paths and driveway edges so the turf ends up flush. The 1,000 sq ft sod and 1,000 sq ft tall fescue seed pages cover the next step.

What you’ll need
- Wheelbarrow (6 cu ft class)Mid-range price
Most home wheelbarrows hold 4–6 cubic feet — so a cubic yard of mulch is five or six trips. Two wheels are steadier on soft ground.

A wide, flat head for dragging topdressing and sand into low spots without burying the grass.
See options on Amazon (opens in a new tab) - Lawn roller (fill with water)Mid-range price
Presses new sod and seed into the soil. Fill it partway — you want contact, not compaction.

Frequently asked questions
How much topsoil for 1,000 sq ft at 6 inches (the deep end for sod)?
About 22.2 cubic yards, roughly 26.7 tons at average moisture. That is the top of the 4 to 6 inch range, and half as much again as the 4 inch figure.
How much topsoil to level 1,000 sq ft of existing lawn at 1/2 inch?
About 1.62 cubic yards with 5% extra (a thin layer barely settles), or 59 bags of 0.75 cu ft. Spread it thin enough that the grass blades still show; for deeper dips, fill in two or more passes.
How many 2 cu ft bags of topsoil would cover 1,000 sq ft at 4 inches?
200 bags of 2 cu ft (or 534 of the common 0.75 cu ft size). At that count, a bulk delivery of 15 cubic yards is the practical way to buy it.
