How to use it
- Measure and enter the area length in feet.
- Enter the project width in feet.
- Enter your desired coverage depth in inches.
- Review your required volume in cubic yards, cubic feet, and estimated tons.
Buying landscaping rock without exact numbers burns cash. If you guess low, you pay double delivery fees for a second truck. If you guess high, you are stuck with expensive stone you cannot return.
This rock calculator turns your project dimensions into exact volume and weight metrics: cubic feet, cubic yards, and estimated US tons.
Quarries and landscape yards sell rock by volume or weight. Having both numbers prevents costly surprises when you place your order. The calculator converts your dimensions directly into cubic yards, then estimates weight using the standard benchmark of 1.4 US tons per cubic yard.
Take the yardage and tonnage figures straight to your supplier. You will know the exact payload requirements for hauling and the precise budget needed before spending a single dollar.
Pro tips
- Add a 10% buffer to your final volume to account for ground settling and irregular trench depths.
- Check your truck bed or trailer payload rating against the estimated tonnage before choosing pickup over delivery.
- Round your order up to the nearest half-yard or whole ton, as most suppliers will not split fractional amounts.
- Measure depth strictly in inches so your volume calculations remain accurate.
Real-life examples
- Calculating crushed stone tonnage for a new two-car residential driveway.
- Determining river rock cubic yardage to mulch garden beds and stop weeds.
- Estimating gravel volume needed to backfill a backyard French drain.
Case study
Mark needed crushed stone for a 60-foot by 12-foot driveway at a 4-inch depth. Instead of guessing, he entered his measurements and got 8.89 cubic yards and 12.45 tons. He added a 10% buffer for compaction and ordered 14 tons in a single delivery, saving $180 in secondary hauling fees.
