Raised Bed Soil
Estimate soil mix volume and bags to fill a raised bed.
About Raised Bed Soil
A raised bed's soil volume is its footprint times the fill depth. Bulk soil is sold by the cubic yard while small bags are sold per bag, so both figures help ordering. Buying the right volume avoids expensive surplus and prevents a bed from settling below a workable depth within the first season.
Formula
Raised Bed Soil
Volume = length x width x depth; yards = feet ÷ 27
- depth
- How deep the growing mix is filled
Worked example
With the default values below, Raised Bed Soil returns Soil in Cubic Feet of 32.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
