How to use it
- Measure the length and width of your area in feet
- Enter the desired gravel depth in inches
- Click Calculate to get cubic yards, tons, and cubic feet
This calculator converts your space dimensions into gravel volume — cubic yards, cubic feet, and estimated tons. Knowing the exact amount prevents over-ordering (wasting money) or under-ordering (delaying your project). The result uses a standard weight estimate of 1.4 tons per cubic yard, which covers most common gravel types. Enter your length and width in feet, then the depth in inches — the tool handles the math instantly. Use the cubic yard figure when ordering bulk deliveries, and the tonnage estimate when comparing supplier quotes. If your area has curves or irregular shapes, break it into rectangles and calculate each section separately, then add the totals.
Pro tips
- Add 10% waste allowance for uneven ground or spillage
- Round up to the nearest half-yard when ordering bulk
- Verify depth with a ruler — guessing leads to over/under orders
- Never confuse cubic yards with tons; they measure different things

Case study
Maria needed gravel for a 20×15 ft driveway at 3 inches deep. The calculator showed 2.8 cubic yards and ~4 tons. She ordered exactly that, avoided a second delivery, and saved hundreds versus her previous 20% overestimate habit.
