How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches.
  4. Read cubic yards, tons and cubic feet results.

What it does – The Fill Dirt Calculator takes the length and width of the area you plan to cover and the desired depth, then instantly converts those dimensions into three useful measures: cubic yards, cubic feet, and an approximate tonnage. Why it matters – Contractors, landscapers, and DIY homeowners need accurate volume estimates to order the right amount of material, avoid costly over‑orders, and ensure the ground is properly compacted. How to read the results – Cubic yards is the standard unit suppliers use for pricing; cubic feet helps you visualize the space; tons gives a quick weight estimate using the industry standard 1.3 US tons per cubic yard. For example, a 20 ft × 15 ft area at 6 in depth equals 5.6 yd³, which is about 7.3 tons. Use the numbers to request quotes and plan delivery.

Pro tips

  • Add a 10% waste allowance to cover settling and spillage.
  • Round up to the nearest whole yard when ordering to avoid shortfalls.
  • Confirm your supplier’s tonnage conversion if they use a different weight per yard.
  • Double‑check depth conversion from inches to feet before entering data.

Real-life examples

  • Homeowner leveling a backyard for a new patio.
  • Contractor preparing foundation fill for a deck build.
  • Landscaper estimating soil volume for a garden berm.

Case study

Mike needed to fill a 12 ft × 20 ft area to a 4‑in depth for his new patio. Using the calculator he saw he required 3.6 yd³, roughly 4.7 tons. He ordered 5 tons, avoiding a shortfall and saving a delivery fee, and the patio was ready on schedule.

Frequently asked questions

How do I convert depth in inches to feet for the calculator?
Divide the inches by 12; the tool handles the conversion when you enter the depth in inches.
Why does the calculator show tons?
Suppliers often price fill dirt by weight; the estimate uses the standard 1.3 US tons per cubic yard.
What if my site isn’t a perfect rectangle?
Break the area into smaller rectangles, calculate each section, then add the results together.
Should I order more than the calculated amount?
Add a 5‑10% waste factor to cover compaction and spillage before placing your order.
Can I use this calculator for sand or gravel?
Yes, the volume calculation is the same; just adjust the weight per yard if your supplier uses a different figure.
