- Surfaces and depths are uniform unless you divide the project into separate sections.
- Waste allowance, manufacturer coverage, and package sizes should be checked before purchasing.
- Site conditions and installation requirements can change the final quantity.
Sources and references
No external data source is required: this calculator uses standard geometry formulas and the measurements you enter.
Worked example
A 20 × 10 ft bed filled 3 inches deep, with 1.5-cu-ft bags at $5.98 each
Needs about 1.85 cubic yards, or 34 1.5-cu-ft bags.
Frequently asked questions
How deep should topsoil be?
For overseeding or leveling, 1 to 2 inches is common. New planting beds often need 3 to 6 inches; follow the needs of your plants and existing soil.
Should I order bags or bulk soil?
Bags are convenient for small jobs. Compare the rounded bag cost with a bulk-delivery quote for larger areas, including delivery and a little extra for settling.
