How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the depth in inches.
- Read the cubic yards, tons and cubic feet results.
What this calculator does
It converts the dimensions of any gravel project—length, width and depth—into three practical units: cubic yards, tons (approx.), and cubic feet. Knowing the volume in cubic yards lets you order the right amount of material; the ton estimate helps you compare pricing across suppliers; cubic feet is useful for smaller jobs or when the supplier quotes in that unit.
How to read the results
- Cubic yards – the primary measure for bulk gravel.
- Tons – calculated at 1.4 US tons per cubic yard, giving a quick weight estimate.
- Cubic feet – 27 ft³ per yard, handy for verification.
Example: A 10 ft × 12 ft patio 4 in deep equals 40 ft³ → 1.48 yd³ → ~2.07 tons.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up to the nearest whole yard for ordering simplicity.
- Check supplier specifications; some quote weight per cubic yard differently.
- Double‑check depth conversion – inches to feet (divide by 12).
Real-life examples
- Planning a new driveway and need the exact gravel quantity.
- Replacing a garden path and want to budget material costs.
- Estimating fill for a backyard retaining wall project.
Case study
Sam needed a 15 ft × 20 ft patio 3 in deep. He entered the numbers, got 2.78 yd³ and 3.89 tons, ordered 3 yd³, and finished without a single delivery shortfall.
