Frequently asked questions
How much soil does a raised bed need?
Multiply the inside length by the inside width and the planned soil depth. The calculator converts the result to cubic metres and litres.
How deep should soil be in a raised bed?
The right depth depends on the plants, the bed construction and the existing ground. Enter the depth you actually plan to fill, then check the plant requirements.
Should I add extra soil for settling?
A modest allowance can cover settling, levelling and small measurement differences. Keep it separate from the planned fill depth so the estimate stays clear.
