How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read the cubic yards, tons, and cubic feet results.
The Gravel Area Calculator turns the three dimensions you input—length (ft), width (ft) and depth (in)—into three useful measures: cubic feet, cubic yards, and an approximate tonnage. Knowing the cubic feet helps you see the raw volume, while cubic yards is the standard unit suppliers use for pricing. Multiplying the cubic yards by 1.4 gives an estimate of how many US tons you’ll need, which is handy for budgeting and truck load planning. The results appear instantly, so you can compare different depths or project sizes without guesswork. No registration is required, and you can copy the numbers directly into a quote request or material list. Cubic yards appear first, followed by tons in parentheses, and cubic feet at the bottom. Because the calculator uses the industry‑standard conversion of 1.4 tons per cubic yard, the ton estimate is close enough for most residential projects.
Pro tips
- Add a 10% waste allowance to avoid shortfalls.
- Round up to the nearest whole yard for easier ordering.
- Order a little extra to cover compaction and uneven sub‑grade.
- Double‑check depth measurement; a 1‑inch error changes volume noticeably.
Real-life examples
- A homeowner planning a 12 ft × 8 ft patio with 3‑inch gravel depth.
- A landscaper estimating material for a 20 ft × 15 ft driveway overlay.
- A DIY gardener calculating gravel for a raised bed garden walkway.
Case study
Sam entered his 10 ft × 6 ft patio dimensions with a 2‑inch depth, got 0.44 cubic yards (≈0.62 tons) and ordered 0.5 yd³. The job finished on schedule without extra trips, saving time and money.
