How to use it
- Enter length, width, and depth.
- Click Calculate.
- Review cubic yards, tons, and cubic feet.
- Add waste allowance before ordering.
This calculator estimates how much crushed stone you need for any rectangular area. Enter the length in feet, width in feet, and depth in inches — it returns cubic yards, tons, and cubic feet instantly.
Why it matters: ordering too little means delays and extra trips; ordering too much wastes money. The tonnage uses the standard industry estimate of 1.4 US tons per cubic yard, so you get a realistic weight figure for hauling and budgeting.
How to read it: cubic yards tell your volume, tons tell your load weight, and cubic feet help if you're buying by the bag. Use the tonnage to confirm your truck or dumpster can handle the load before you commit.
No invented formulas here — just the constants you need to plan confidently and avoid costly mistakes on-site.
Pro tips
- Add 10% waste allowance for settling and cuts.
- Round up to the nearest half-yard when ordering.
- Confirm truck weight limits before hauling.
- Never confuse cubic feet with cubic yards.
Real-life examples

Case study
Before: Mark ordered 5 yards without calculating and ended up 1.5 yards short, delaying his patio by two weeks. After: He used the calculator, entered 40ft × 20ft × 4in depth, got 9.9 cubic yards and 13.9 tons, ordered correctly, and finished on schedule.
