How to use it

  1. Enter the length in feet.
  2. Enter the width in feet.
  3. Enter the depth in inches.
  4. Click Calculate to see cubic yards, cubic feet, and tons.

What it does – The Fill Dirt Calculator takes the length and width of your area in feet and the desired depth in inches, then instantly returns three values: volume in cubic yards, volume in cubic feet, and an estimated weight in US tons. Why it matters – Knowing the exact amount of fill prevents over‑ordering, which saves money and reduces truck trips, or under‑ordering, which can delay a project. Reading the results – Cubic yards is the standard unit for ordering bulk fill. Cubic feet helps you visualize the space on‑site. Tons uses the industry‑standard estimate of 1 cubic yard ≈ 1.3 US tons, so you can compare material weight to truck capacity. Enter your dimensions, click Calculate, and you’ll have the numbers you need to place an accurate order right away.

Pro tips

  • Add 5‑10% extra for compaction and waste.
  • Round up to the nearest whole cubic yard for easier ordering.
  • Check truck load limits before ordering by weight (tons).
  • Double‑check that depth is entered in inches, not feet.

Real-life examples

  • A homeowner preparing a backyard garden bed needs to know how much fill to order.
  • A contractor leveling a driveway wants precise volume to avoid delays.
  • A landscaper estimating material for a park pathway grading project.

Case study

Sam entered his patio dimensions (12 ft × 8 ft × 4 in) and instantly saw 1.2 cubic yards, 32 cubic feet, and 1.6 tons. He ordered exactly that amount, saved $200 on excess fill, and completed the project on schedule.

Frequently asked questions

Should I order extra?
Yes — add about 10% for settling, spillage and uneven ground. Weights are approximate and rise when the material is wet.
