How to use it
- Enter length in feet
- Enter width in feet
- Enter depth in inches
- Read cubic yards, tons and cubic feet results
Enter the length, width, and desired depth of your gravel area and the calculator instantly returns three key figures: total cubic feet, cubic yards, and an approximate tonnage. Knowing cubic yards tells you how many bulk bags to order, while cubic feet helps with smaller projects or when comparing to patio tile volumes. The ton estimate uses the industry‑standard 1.4 US tons per cubic yard, giving you a realistic shipping weight for truck quotes. Results appear in clear units, so you can match them to supplier specifications without extra conversions. Use the numbers to budget material costs, avoid under‑ordering, and plan delivery logistics with confidence. You can also compare different depth options side‑by‑side to see how material needs grow, making it easy to choose the most cost‑effective design.
Pro tips
- Add 5‑10% extra for compaction and spillage
- Round up to the nearest whole cubic yard for ordering
- Check supplier minimum tonnage before finalizing
- Verify depth measurement in inches, not feet
Real-life examples

Case study
Mike needed 500 sq ft of driveway gravel 3 in deep. Using the calculator he saw he required 1.85 cubic yards, about 2.6 tons. He ordered 2 tons plus a 10% waste allowance, saved $150 by avoiding an extra truck, and his project finished on schedule.
