  4. Click Calculate to see cubic yards, tons and cubic feet.

What this calculator does

It turns the three dimensions of your project—length, width and depth—into three useful measures: cubic yards, approximate tons, and cubic feet. Knowing the yardage tells you how much material to order, while the ton estimate helps you compare pricing across suppliers that quote by weight. The cubic‑foot figure is handy for checking against local building codes or for mixing with other materials.

How to read the results

  • Cubic yards – the standard unit for bulk gravel deliveries.
  • Tons (approx) – calculated at 1.4 US tons per cubic yard, giving a quick weight estimate.
  • Cubic feet – the raw volume before conversion, useful for on‑site calculations. Use these numbers to avoid over‑ordering, stay within budget, and keep your project on schedule.

Pro tips

  • Add 5‑10% extra for compaction and spillage.
  • Round up to the nearest whole yard for ordering convenience.
  • Check supplier weight limits; some deliver by ton, others by yard.
  • Double‑check depth conversion from inches to feet before entering data.

Real-life examples

  • A homeowner planning a new driveway needs to know how many yards of gravel to order.
  • A landscaper estimating material for a garden path wants both volume and weight for pricing quotes.
  • A contractor preparing a base for a patio calculates cubic feet to verify compliance with local regulations.

Case study

Sam entered a 12 ft × 8 ft area with a 4‑inch depth. The calculator returned 0.89 yd³ (≈1.25 tons) and 24 ft³, letting him order the exact amount and avoid a costly over‑order.

Frequently asked questions

How do I convert depth from inches to feet?
Divide the inch value by 12; the calculator does this automatically.
Why is the ton estimate only approximate?
It uses a standard density of 1.4 US tons per cubic yard, which varies slightly with gravel type.
Do I need to round the results?
Round up to the nearest whole yard or ton to ensure you have enough material.
Can I use the calculator for sand or mulch?
The volume conversion works, but weight estimates will differ; use the appropriate density for those materials.
Is there a limit to the size of the project I can calculate?
No; enter any length, width and depth values the tool can handle.
