- Click Calculate to see cubic yards, tons and cubic feet.
What it does – The Bluestone Gravel Calculator turns the dimensions of your project into three practical measures: cubic feet, cubic yards and an approximate tonnage. Knowing the cubic yards tells you how many bulk bags or truckloads to order; the ton estimate helps you compare pricing per ton and avoid over‑paying; cubic feet is useful for smaller jobs or when you need to fill a container. The tool uses the standard conversion (1 cubic yard = 27 cubic feet) and a weight factor of 1.4 US tons per cubic yard. Simply input length, width and depth, and the results appear instantly. Read the cubic yard number for bulk orders, the ton figure for budget planning, and the cubic foot value for precise fill calculations.
Pro tips
- Add 5‑10% extra volume for compaction and breakage.
- Round up to the nearest half‑yard to simplify ordering.
- Check the supplier’s ton rating; adjust if they use a different weight per yard.
- Measure depth in inches, then convert to feet (divide by 12) before entering.
Real-life examples
- A homeowner planning a 12 ft × 8 ft patio with 3 in depth gravel.
- A landscaper estimating material for a 20 ft × 15 ft driveway at 4 in depth.
- A DIYer needing the exact tonnage to order from a supplier who sells by the ton.
Case study
Sarah needed a 10 ft × 12 ft patio with 4 in depth. Using the calculator she saw she required 1.5 cubic yards, about 2.1 tons. She ordered that amount, avoided a costly second delivery, and completed the patio on schedule.
