How this is calculated
volume ft³ = area × (depth ÷ 12); cubic yards = ft³ ÷ 27; tons ≈ yd³ × 1.1
- Screened topsoil weighs roughly 1.1 US tons per cubic yard; wet soil is heavier.
- Allow 4–6 in for a new lawn, 2 in for top-dressing an existing one.
Häufig gestellte Fragen
How does the Topsoil Calculator work?
It applies the formula volume ft³ = area × (depth ÷ 12); cubic yards = ft³ ÷ 27; tons ≈ yd³ × 1.1. Enter your measurements and the result updates instantly in your browser — nothing is uploaded and no sign-up is needed.
Why should I include a waste allowance?
Offcuts, spillage, breakage and an uneven sub-base all consume material that the raw geometry does not account for. The default allowance is deliberately modest; increase it for complex layouts, and remember that running short usually costs more in a second delivery than the surplus did.
Are the results exact?
They are a close estimate, not a guarantee. Screened topsoil weighs roughly 1.1 US tons per cubic yard; wet soil is heavier. Real materials vary by supplier, moisture content and compaction, so confirm the rate with your supplier before placing a large order.
Is this tool free?
Yes, completely free with no registration. All calculations happen client-side in your browser.
Does it work on mobile?
Yes. The calculator is fully responsive and works on phones and tablets in any modern browser — useful when you are measuring on site.

About the Topsoil Calculator
The Topsoil Calculator estimates the topsoil required to fill or top-dress an area, in cubic yards for bulk orders and in US tons for weight-based pricing. Enter your measurements and the result updates as you type — there is nothing to submit and nothing to wait for.
Everything runs in your browser. Nothing you enter is sent to a server, there is no sign-up, and there is no usage limit.
Who it's for
Anyone levelling a garden, starting a lawn, or filling raised beds.
How the calculation works
volume ft³ = area × (depth ÷ 12); cubic yards = ft³ ÷ 27; tons ≈ yd³ × 1.1
The result depends on a few standard constants, which are stated on the page rather than hidden:
- Screened topsoil weighs roughly 1.1 US tons per cubic yard; wet soil is heavier.
- Allow 4–6 in for a new lawn, 2 in for top-dressing an existing one.
Getting an accurate estimate
Measure twice. Small errors in a linear dimension compound, because material volume scales with two or three of them at once — a 6-inch error across a 20-foot run is over a cubic foot of material on a 4-inch pour.
Keep the waste allowance. The default is deliberately conservative: offcuts, spillage, uneven sub-base and breakage are all real, and running short mid-job usually costs more in a second delivery than the surplus did.
Round up when you order. Suppliers sell in fixed increments — quarter yards, whole bags, full boxes — so treat the figure here as the minimum you need rather than the exact amount to buy.
