What it does – The Landscaping Rock Calculator turns the dimensions of your project (length, width, depth) into three useful measures: cubic yards, cubic feet, and an approximate tonnage. Why it matters – Knowing cubic yards tells you how many rock bags or deliveries to order; cubic feet helps when you’re filling a container or comparing to other materials; tons give you a realistic weight for transport and cost estimates. How to read the results – The cubic‑yard value is the standard volume used by suppliers. Multiply by 1.4 (the constant) to get tons – the tool does this for you. The cubic‑foot figure is simply the volume in a more familiar unit for DIY checks. Use the numbers to order the right amount without costly over‑ or under‑ordering.
Pro tips
- Add 5‑10% extra volume for compaction and breakage.
- Round up to the nearest 0.1 cubic yard for ordering.
- Confirm the supplier’s weight per cubic yard matches 1.4 tons before final quote.
- Measure depth at several points and use the average to avoid under‑estimation.
Real-life examples
- A homeowner planning a 200‑sq‑ft patio wants to know how many tons of river rock to order.
- A landscape contractor estimating rock for a drainage swale needs cubic feet to match excavation plans.
- A DIY gardener filling raised beds with decorative stone checks the cubic yards to compare bulk prices.
Case study
Mike wanted a 10 ft × 12 ft × 4 in rock border. Using the calculator, he saw he needed 1.33 cubic yards, about 1.86 tons. He ordered 2 tons, saved a delivery fee, and finished the project on budget.
