Raised Bed Soil Calculator
Calculate soil volume for raised beds, in litres, cubic metres and bags.
What this page needs from you
This page asks for bed length in cm, bed width in cm, soil depth in cm and number of beds. From those it returns soil needed in L, together with in cubic metres, bags at 50 l, per bed and weight when moist. Every figure updates as you type, and nothing you enter leaves your browser.
Rates are regional, and local advice beats a general figure
Soil type, rainfall, variety and season change the right answer more than the arithmetic does. Use this to plan and to check an order, and check the figure against your local extension service, agronomist or supplier before committing to a whole field.
The formula
Volume = length × width × depth × number of beds
Every result on this page comes from this formula. Nothing is rounded until the final display, so figures match a spreadsheet to the cent.
