Garden Soil
Find soil volume and bags needed for a raised garden bed.
About Garden Soil
Length, width and depth in feet give cubic feet of soil, which converts to yards and to the number of bags needed. Buying soil for a raised bed is easy to overshoot or undershoot, and volume math keeps the order right-sized.
Formula
Garden Soil
Volume = L x W x depth(ft); cubic yards = volume / 27; bags = volume / bag size
- bag size
- Volume of soil in a single retail bag

Assumptions and limits
- The result is derived only from the 4 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.
