How to use it
- Enter the length of the area in feet
- Enter the width in feet
- Enter the depth in inches
- Click Calculate to see cubic yards, tons, and cubic feet
This crusher run calculator tells you exactly how much material you'll need for driveways, paths, or base layers. Just enter your length, width, and depth, and it instantly converts everything into cubic yards, cubic feet, and approximate tons using a standard weight of 1.4 US tons per cubic yard. That tonnage matters because suppliers sell crusher run by the ton, not by volume. The calculator also gives you cubic yards, which is what you'll use to compare with dump truck capacity or bulk bag sizes. Reading the results is simple: use the cubic yard figure to plan the order, use the tonnage to estimate cost and trucking, and use cubic feet if you're comparing with smaller deliveries. Depth is the trickiest input — the difference between 3 and 4 inches may not look like much, but it changes your total by over 30%. This tool takes the guesswork out, so you order the right amount the first time.
Pro tips
- Add 10% waste for compaction and spillage — crusher run settles and you don't want to run short
- Round up to the nearest half ton when ordering — trucks don't deliver partial bags
- Use the cubic yard result to confirm your supplier's minimum — many charge extra for small loads
- Measure depth after grading, not before — a 4-inch compacted base needs more material than 4 inches of loose fill
Real-life examples
- Filling a 12x20 gravel driveway base with 4 inches of crusher run
- Creating a stable sub-base for a 10x12 garden shed on compacted soil
- Laying a 3-inch crusher run bed for a paver patio project
Case study
Mark prepped a 10x14 shed base with 6 inches of crusher run. He guessed he needed 3 tons, but the calculator said 2.6 cubic yards — about 3.7 tons. He ordered 4 tons, saved a second delivery fee, and finished the base in one afternoon.
