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 calculator converts the dimensions of your planting area (length, width, depth) into three useful measures: cubic yards, cubic feet, and approximate tons of rock. Knowing the volume helps you order the right amount, avoid costly over‑orders, and ensure the surface is level and stable. Why it matters – Landscape rock is heavy; ordering too little means extra trips, ordering too much wastes money and space. The ton estimate uses the industry standard of 1.4 US tons per cubic yard, giving you a realistic weight for delivery quotes. How to read the results – Cubic yards is the primary unit for most suppliers; cubic feet lets you visualize the pile; tons shows the load weight. Use the numbers to compare quotes and plan delivery logistics.
Pro tips
- Add 5‑10% extra for compaction and breakage.
- Round up to the nearest whole cubic yard for ordering simplicity.
- Order a little more than the ton estimate to cover weight variations.
- Double‑check depth conversion from inches to feet before entering data.
Real-life examples
- A homeowner plans a new rock garden and needs to know how much material to order.
- A contractor is quoting a driveway base and wants accurate volume and weight for delivery costs.
- A landscaper is replacing mulch with rock and must calculate the total load for the truck.
Case study
Sam entered his 12 ft × 8 ft patio dimensions with a 4‑inch depth, got 2.9 cubic yards (≈4.1 tons) and ordered 3 cubic yards, avoiding a second delivery and saving $150.
