How Much Topsoil Do I Need?

For a new lawn, 4–6 inches of topsoil over existing subsoil is typical. For a raised garden bed, plan for 6–12 inches depending on what you're planting — root vegetables and larger plants need more depth.

Topsoil settles after the first watering, so many gardeners order slightly more than the bare calculation and top off later rather than under-filling the bed.

Measure your bed or lawn area, pick a depth, and the Topsoil Calculator will give you cubic yards and estimated weight.
