New garden beds typically need 4–6 inches of topsoil, raised-bed topping 2–4 inches, and lawn leveling only ½–1 inch. Topsoil is heavy — about 1.1 tons per cubic yard — so plan delivery for anything over a yard.
The math: 300 sq ft × depth in feet ÷ 27 = cubic yards. One cubic yard of topsoil covers 162 sq ft at 2" · 81 sq ft at 4" · 54 sq ft at 6".
For lawn top-dressing at ½ inch, divide the ½-inch numbers from the 1-inch figure — or use the calculator with a custom depth.
