How it works
Cubic yards = area (sq ft) × depth (in) ÷ 324Frequently Asked Questions
How much topsoil do I need?
Area × depth: a 200 sq ft bed filled 6 inches deep needs about 3.7 cubic yards. For raised beds, use the bed's length × width × fill depth.
How many bags of topsoil in a cubic yard?
About 27 of the common 1 cubic-foot bags, or roughly 13.5 of the 2 cubic-foot bags. Bulk delivery is far cheaper beyond a yard or two.
How deep should topsoil be for a lawn or garden?
4–6 inches for new lawns and most planting beds; 8–12 inches for vegetable beds and deep-rooted plants. Enter your target depth for an accurate volume.
