Soil Calculator
Calculate soil volume required for a garden or planting area.
Calculation example
Inputs: Length: 10 ft, Width: 10 ft, Depth: 0.5 ft
Result: 50 cubic units
A 10 ft by 10 ft bed with a 0.5 ft depth needs 50 cubic feet of soil.
Formula
Soil volume = length × width × depth.
How to use this calculator
Multiply length by width by depth using consistent units.
Before you calculate
Measure the project dimensions as accurately as practical and keep all measurements in compatible units. For material products, use the coverage, yield, density, or package size stated by the manufacturer or supplier rather than a generic assumption.
Choose the waste allowance based on the project shape, installation method, cutting requirements, and material characteristics. A simple rectangular estimate may need adjustment for openings, corners, slopes, joints, patterns, compaction, or other site conditions.
Understanding the result
The calculator provides a planning estimate based on the inputs shown above. It is not a substitute for project drawings, structural design, manufacturer instructions, or local requirements. Before ordering, compare the calculated quantity with the supplier's package sizes and ordering units.
Tips
- Account for settling and the finished grade when choosing an order quantity.
Frequently asked questions
