Calculate the compost needed for a measured area at a chosen application depth.
Use this as a planning estimate. Verify product labels, local conditions and supplier packaging before buying or applying materials.
Compost volume = garden area × application depth ÷ 12. The result is shown as cubic feet, cubic yards and whole bags.
SproutScale preserves full precision while calculating and rounds only the displayed result or the final purchasable unit.
A 1-inch layer over 100 square feet equals about 8.33 cubic feet, or 0.31 cubic yards.
Usually no. Compost is an amendment; most beds perform better with a balanced mineral soil and organic matter blend.
