Soil & bag calculator
Turn bed dimensions into cubic feet, cubic yards, and a bag count.
1.19 cubic yards · 906.14 litres
16 bags at 2 cubic feet each, including your 0% allowance.
Formula: length × width × depth ÷ 12. Bag counts round up after adding your allowance. This assumes a rectangular area. Depth is your input, not a crop recommendation. Subtract existing fill before measuring your required depth. Soil settling and supplier measurements vary; this tool estimates quantity, not soil composition.

Keep your plan grounded.
Use the result as a starting point. Crop spacing, fill depth, sowing windows, and care needs depend on the crop and your conditions. University of Maryland Extension’s beginner guidance is a useful companion.
