Calculate Your Soil Volume

Shape

Units

Length (ft)

Width (ft)

Fill depth (in)

Typical raised bed: 6–12″. New lawn: 4–6″.

The math:

Cubic Feet = Length × Width × (Depth ÷ 12)

Liters = Cubic Feet × 28.32 · Cu Yd = Cubic Feet ÷ 27

You need approximately

cubic feet of soil

That's about

453.1 L

(0.59 cu yd)

Liters useful for bag shopping

Or buy in bags (standard retail potting mix sizes)

× 8 qt bags

× 16 qt bags

× 25 qt bags

~640 lbs / ~290 kg (est. weight at 40 lbs/cu ft). Add 10–15% for settling.
