How much does a yard of topsoil cover?

Cubic yards = area (sq ft) × depth (in) ÷ 12 ÷ 27. The calculator then adds the buffer for compaction and spreading and rounds up.

Topsoil mistakes to avoid

Topsoil too shallow

A 1-inch layer over compacted clay fails. Roots cannot establish. Plan 4–6 inches for new lawns, more for beds.

Skipping the subgrade prep

Topsoil on top of compacted construction subsoil drains poorly. Loosen the top 4 inches of subgrade before spreading topsoil.

Wrong soil type

Florida "screened topsoil" is mostly sand. For vegetable gardens you want a garden soil mix with compost — see related calculators.

Forgetting settlement

Topsoil settles 10–20% in the first month after watering. Order to your finished grade, not the freshly dumped pile.

Topsoil calculator questions

Length × Width × Depth ÷ 27 (depth in inches divided by 12). A 1,000 sq ft lawn at 4 inches needs about 13 cubic yards.
