What the Gravel Estimate Calculator does
The tool converts the dimensions you provide—length, width, and depth—into three practical measures: cubic feet, cubic yards, and an approximate weight in US tons. Knowing the cubic footage tells you how much space the material will occupy, while cubic yards are the standard unit suppliers use for pricing and delivery. Multiplying the cubic yards by 1.4 tons gives a quick weight estimate, helping you verify that your truck or crew can handle the load. Simply input the numbers and the calculator instantly shows the three results, so you can order the right amount, avoid costly over‑orders, and keep your project on schedule. The calculator also displays the volume in cubic feet, which is useful when you need to compare against existing material on site or calculate the fill needed for a specific pit. Because the weight estimate uses a fixed 1.4 tons per cubic yard, it works well for typical crushed stone, limestone, and pea gravel.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up to the nearest half‑yard for easier ordering.
- Check supplier minimum loads before finalizing quantity.
- Measure depth in inches accurately; a 1‑inch error changes volume by ~0.04 yd³.
Real-life examples

Case study
Mike needed about 5 cubic yards for his driveway. Using the calculator he entered 12 ft × 20 ft × 4 in, got 5 yd³, added a 5% waste factor, and ordered 5.3 yd³, saving $150 by avoiding an over‑order.
