Figuring Gravel Calculator

How to use it

1. Measure and enter your project's length and width in feet.
2. Enter the target gravel depth in inches.
3. Review your total cubic feet, cubic yards, and required tons instantly.

Buying gravel without exact numbers leads to two expensive mistakes: paying for a second delivery fee or sitting on an unusable pile of stone. This tool converts your surface area and planned depth directly into cubic feet, cubic yards, and total weight in US tons.

Quarries and landscape suppliers sell gravel by weight, not volume. This calculator uses the industry standard benchmark of 1.4 tons per cubic yard. For example, an area measuring 20 feet by 10 feet at 3 inches deep requires 50 cubic feet of material. That equals 1.85 cubic yards, translating directly to 2.59 tons.

Use the cubic yard figure when dealing with bulk dirt or compost suppliers, and use the tons metric when placing your gravel haul order. You walk into the landscape yard knowing the exact tonnage you need, keeping your job on schedule and your budget locked in.

Pro tips

• Add a 10% waste buffer to account for ground compaction, slope variations, and wheelbarrow spill.
• Always round up your final weight to the nearest half-ton or ton, as commercial quarries load via heavy bucket scales.
• Confirm delivery access before ordering; a split tandem truck requires solid ground and overhead clearance.
• Measure depth in multiple spots across uneven ground to avoid underestimating your true volume.

Real-life examples

• Building a 4-inch deep gravel base for a backyard shed or patio paver foundation.
• Resurfacing an existing driveway that has developed low spots, ruts, and washed-out edges.
• Installing pea gravel borders and walkways around raised garden beds.

Case study

Marcus planned a 50-foot gravel parking strip and guessed he needed three truckloads. Instead of guessing, he entered 50 feet by 12 feet at 4 inches deep. The calculator showed 7.41 cubic yards, or 10.37 tons. Marcus ordered 11.5 tons with a waste margin, saved a $150 second delivery charge, and finished the installation in one afternoon without excess material.
