How to use it
- Enter length in feet
- Enter width in feet
- Enter depth in inches
- Read cubic yards, tons and cubic feet results
What it does The Rip Rap Rock Calculator turns the length, width and depth of your project into three key numbers: cubic yards, tons (approx) and cubic feet. Knowing the cubic yards tells you how many truckloads to order; the ton estimate helps you budget for material cost; cubic feet is useful for comparing with other site‑specific measurements. The tool uses the standard conversion that 1 cubic yard of rip‑rap weighs about 1.4 US tons. Simply input your dimensions and the calculator instantly returns the three results, so you can order the right amount without costly over‑ or under‑estimates.
Pro tips
- Add 5‑10% extra for spillage and compaction
- Round up to the nearest whole cubic yard when ordering
- Verify your local supplier’s ton‑per‑cubic‑yard rating; 1.4 tons is typical
- Double‑check depth units; inches must be entered, not feet
Real-life examples
- A homeowner planning a 150‑ft retaining wall needs to know rock quantity
- A landscaper estimating material for a 30‑ft garden stream bed
- A contractor sizing rip‑rap for a storm‑drain outlet
Case study
Sam entered a 120 ft length, 15 ft width and 8 in depth; the calculator showed 53 cubic yards (≈74 tons). He ordered 55 yards, avoided a short‑fall and saved $300 on extra truck trips.
