How to use it
- Enter length (ft), width (ft) and depth (in).
- Click “Calculate”.
- Read the cubic feet, cubic yards and ton estimate.
Rock and Gravel Calculator instantly converts your project dimensions into the exact amount of material you’ll need. Enter the length, width and depth of the area, and the tool returns cubic feet, cubic yards, and an approximate tonnage based on the industry standard of 1.4 US tons per cubic yard. Knowing the volume helps you price the job, avoid over‑ordering, and plan delivery logistics. Cubic feet is useful for small‑scale jobs, while cubic yards is the common unit for suppliers. The ton estimate gives you a quick sense of weight for truck capacity and cost. All results appear instantly, so you can adjust dimensions on the fly and see how changes affect material needs. You can also compare multiple scenarios by changing one measurement at a time, which is ideal for budgeting and preventing costly surprises on the job site.
Pro tips
- Add 10% extra for compaction and breakage.
- Round up to the nearest whole cubic yard when ordering.
- Check truck capacity using the ton estimate before delivery.
- Double‑check depth conversion from inches to feet to avoid under‑estimation.
Real-life examples
- A homeowner planning a new driveway needs to know how much gravel to order.
- A landscaper preparing a garden path wants the exact rock volume for budgeting.
- A contractor estimating fill material for a foundation trench.
Case study
Mike needed 10 ft of 4‑in‑deep gravel for his patio. Using the calculator, he entered 12 ft × 8 ft × 4 in and saw 0.99 cubic yards ≈ 1.4 tons. He ordered 1 cubic yard, saved $200, and avoided a half‑load return.
