How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the depth in inches.
- Read the cubic yards, tons and cubic feet results.
What it does The Crushed Rock Calculator turns the length, width and depth of your project into three practical measurements: cubic yards (the standard ordering unit), tons (weight for delivery quotes) and cubic feet (easy on‑site reference).
Why it matters Knowing cubic yards prevents under‑ordering, while the ton estimate helps you compare freight costs. The cubic‑foot figure lets you visualize how deep a layer will sit in your space.
How to read the results
- Cubic yards: total volume you’ll order.
- Tons: multiply cubic yards by 1.4 US tons.
- Cubic feet: raw volume before conversion.
Example: A 10 ft × 5 ft area at 4 in depth yields 0.62 cubic yards, 0.86 tons and 16.7 cubic feet.
Use the ton figure to request quotes from multiple suppliers; most will price per ton. Add a 5‑10% waste factor to ensure you have enough material after compaction.
Pro tips
- Add 5‑10% extra for compaction and breakage.
- Round up to the nearest tenth of a cubic yard for ordering simplicity.
- Check supplier minimums; some sell by the ton, others by the cubic yard.
- Double‑check depth units; the calculator expects inches, not centimeters.

Case study
Maria entered her 12 ft × 8 ft driveway area with a 3‑inch depth and instantly saw she needed 0.78 cubic yards (1.09 tons). She ordered 0.8 cubic yards, avoided a costly over‑order, and completed the job on schedule.
