What it does – This free tool converts the dimensions of your garden, driveway, or patio into three practical measures: cubic yards, cubic feet, and an approximate weight in US tons. Knowing the volume helps you order the right amount of pea gravel, avoiding costly over‑orders or frustrating shortfalls. The calculator assumes a standard density of 1.4 tons per cubic yard, a widely accepted industry estimate, so the tonnage figure is a reliable guide for budgeting and delivery quotes. How to read the results – Cubic yards is the primary unit most suppliers quote. Multiply by 1.4 to see the tons (shown automatically). Cubic feet offers a finer‑grain view for small projects or when comparing to other materials. Use these numbers to place an accurate order and keep your project on schedule.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up to the nearest whole cubic yard for supplier quotes.
- Order by weight if the supplier quotes in tons; use the calculator’s ton estimate.
- Double‑check depth; a 2‑inch change can add or subtract a full cubic yard.
Real-life examples
- A homeowner planning a 12 × 15 ft patio with a 3‑inch gravel base.
- A landscaper needing pea gravel for a 500 sq ft garden path, 2 in deep.
- A DIY enthusiast ordering material for a driveway border, 8 × 20 ft at 4 in depth.
Case study
Jane needed pea gravel for a 10 × 12 ft patio at 3 in depth. Using the calculator she saw she required 0.9 cubic yards, about 1.3 tons. She ordered 1 cubic yard, saved $45 on excess material, and the project stayed on schedule.
