What it does

The Yards Of Dirt Calculator converts your project dimensions into three practical measures: cubic yards, tons (approx.), and cubic feet. Knowing the cubic yards tells you how many truckloads to order, while the ton estimate helps you budget for material cost. Cubic feet is useful for comparing against product specifications.

Why it matters

A mis‑calculated volume can lead to costly over‑orders or a shortage that stalls the job. This tool gives you an instant, reliable snapshot so you can order the right amount the first time.

How to read the results

  • Cubic yards – total volume divided by 27 (the number of cubic feet in a yard).
  • Tons – multiply cubic yards by 1.3 (the constant we use for US tons per cubic yard).
  • Cubic feet – raw volume before conversion.

Pro tips

  • Add a 5‑10% waste allowance for compaction and spillage
  • Round up to the nearest half‑yard for easier truck scheduling
  • Compare the ton estimate with supplier specs before ordering
  • Double‑check depth conversion from inches to feet to avoid errors

Real-life examples

  • Planning a new garden bed and need to know how much topsoil to buy
  • Estimating fill material for a driveway repair project
  • Calculating dirt needed to level a backyard patio area

Case study

Sam needed to fill a 12 ft × 8 ft area to a 4‑inch depth. The calculator showed 1.18 cubic yards, about 1.5 tons. He ordered exactly that amount, avoiding a $200 over‑order and finishing on schedule.

Frequently asked questions

How do I convert depth in inches to feet?
Divide the inches by 12; the calculator does this automatically.
Why is the ton estimate only approximate?
We use a standard weight of 1.3 US tons per cubic yard, which is typical for dry fill dirt.
Do I need to include compaction in the calculation?
Add a 5‑10% waste factor to the cubic yard result to cover compaction.
Can I use this for sand or gravel?
The volume conversion works, but weight per yard differs; use supplier‑specific weights.
Is the calculator really free?
Yes, it’s completely free with no sign‑up required.
