How to use it
- Enter length (ft), width (ft) and depth (in).
- Click the Calculate button.
- Read the cubic yards, tons (approx) and cubic feet results.
What it does – The calculator turns your garden dimensions (length ft × width ft × depth in) into three practical measures: total cubic feet, cubic yards, and approximate tons of rock. Why it matters – Knowing cubic yards tells you how many bulk deliveries to order; tons helps you compare weight limits for trucks; cubic feet is useful for small‑scale fill. How to read – The cubic‑feet number is the raw volume. Divide by 27 to see cubic yards (the standard bulk unit). Multiply cubic yards by 1.4 to get an approximate tonnage, which matches most supplier estimates. All results update instantly, so you can tweak dimensions and see the impact on cost and material needs right away. Use the cubic‑yard figure to request quotes from local quarries; most price lists are per yard. When ordering, add a 5‑10 % waste factor to avoid shortfalls. The ton estimate is handy for checking crane or truck capacity limits.
Pro tips
- Add 5‑10 % extra volume to cover breakage and compaction.
- Round up to the nearest whole cubic yard for ordering simplicity.
- Check supplier minimum delivery sizes before finalizing the order.
- Confirm truck load limits using the ton estimate to avoid over‑loading.

Case study
Sam needed a new rock border for his backyard. He entered 30 ft × 20 ft × 4 in and the calculator gave 1.78 cubic yards, 2.5 tons (approx), and 48 cubic feet. He ordered 2 cubic yards, added a 10 % waste allowance, and finished on budget without extra trips.
