How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the desired depth in inches.
- Read the cubic yards, tons, and cubic feet results.
What it does – This free tool takes the length, width and desired depth of a pea‑gravel project and instantly returns three useful measures: cubic yards (the standard ordering unit), the equivalent weight in US tons, and the raw cubic‑feet volume. Why it matters – Knowing the exact yardage prevents costly over‑ordering and ensures you have enough material for a stable surface. How to read the results – Cubic yards is what suppliers quote; multiply by 1.4 to see the approximate tons. Cubic feet shows the raw space you’ll fill. Example: a 10 ft × 10 ft patio at 2 in depth yields 0.62 yd³ (≈0.86 tons) or 16.7 ft³.
Pro tips
- Add 5‑10% extra for compaction and breakage.
- Round up to the nearest whole yard because most suppliers sell by the yard.
- Order a little more if you plan multiple layers or a sloped surface.
- Double‑check depth conversion (inches to feet) before entering.
Real-life examples
- Planning a new garden pathway and need the exact amount of pea gravel to order.
- Replacing driveway base material and want to avoid ordering too much.
- Estimating material for a backyard fire pit surround to stay within budget.
Case study
John wanted a 12 ft × 8 ft patio with 2 in depth. Using the calculator he saw he needed 0.71 yd³ (≈1.0 ton) or 19.2 ft³, ordered exactly that amount, saved $120 on excess material, and completed the project on schedule.
