How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches and hit Calculate.
The Gravel Shop Calculator lets you turn simple length, width, and depth measurements into the exact volume of material you’ll need. By converting feet and inches to cubic yards, the tool also shows the equivalent in cubic feet and an estimated weight in tons (using the industry standard 1.4 US tons per cubic yard). Knowing these numbers helps you budget accurately, avoid costly over‑orders, and communicate clear specifications to suppliers. The calculator automatically converts depth from inches to feet before multiplying, then divides by 27 to turn cubic feet into cubic yards. The result panel displays three values: Cubic Yards – the primary ordering unit, Tons (approx) – useful for freight and cost estimates, and Cubic Feet – handy for on‑site calculations. Simply enter your dimensions, click Calculate, and you get an instant, free readout ready for quotes or purchase orders.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up to the nearest whole cubic yard for easier ordering.
- Check supplier’s density; 1.4 tons per cubic yard is a typical estimate.
- Verify depth conversion from inches to feet before input.
Real-life examples
- Homeowner installing a 6‑ft wide driveway.
- Landscaper planning a garden path 4 ft by 10 ft at 2 in depth.
- DIY backyard patio needing 8 ft by 12 ft area with 3 in gravel base.
Case study
Mike needed a 6 × 12 ft patio with a 2‑in gravel base. Using the calculator he saw he required 0.44 cubic yards ≈ 0.62 tons. He ordered 1 cubic yard, saved a delivery fee and avoided ordering excess material.
