How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches and click Calculate.

What it does – The calculator turns the dimensions of your gravel area into three practical units: cubic yards, cubic feet, and an approximate tonnage. Why it matters – Knowing cubic yards lets you order the right volume from the supplier; cubic feet helps when you’re comparing different fill depths; tonnage is useful for budgeting since most vendors quote price per ton. How to read the results – The tool converts the yardage into tons using the industry standard of 1.4 tons per cubic yard. The cubic‑foot number is simply the yardage converted to a smaller unit for quick reference. Use these numbers to place an accurate order and avoid costly over‑or under‑ordering. The instant output saves you time on phone calls and prevents guesswork when budgeting.

Pro tips

  • Add 5‑10% extra for compaction and spillage.
  • Round up to the nearest half‑yard for easier ordering.
  • Order a little more than the ton estimate if the supplier only sells in full tons.
  • Double‑check depth measurement; many people mistake inches for feet.

Real-life examples

  • Homeowner laying a new driveway path.
  • Landscape contractor filling a garden bed.
  • DIY enthusiast building a patio base.

Case study

Mike needed a 12 ft × 8 ft patio base 4 in deep. Using the calculator he saw he required 2.7 cubic yards (≈3.8 tons). He ordered 4 tons, avoiding a second delivery and saved $120 compared to over‑ordering.

Frequently asked questions

How do I convert depth from inches to feet?
Enter the depth in inches as prompted; the calculator handles the conversion internally.
Why does the ton estimate differ from the supplier’s quote?
The tool uses a standard 1.4 tons per cubic yard; actual weight can vary slightly with moisture and stone size.
Can I use this for sand or mulch?
The volume calculations are the same, but weight per yard differs; adjust using the material’s specific density.
Do I need to include a waste factor?
Add 5‑10 % to the cubic‑yard result for compaction and spillage before ordering.
Is the result in US tons?
Yes, the calculator reports tons using the US short ton (1 ton = 2000 lb).
