How much topsoil do I need?
Multiply the area by the depth you want to fill. For a new lawn, 4–6 inches (10–15 cm) of good topsoil gives grass roots space to establish; raised vegetable beds usually need 8–12 inches (20–30 cm).
Weight is estimated at 1.4 tonnes per cubic metre, a typical figure for moist screened topsoil. Wet or clay-heavy soil weighs more.
