Gravel Calculator
Gravel is ordered by weight, but you measure the space by volume. Enter the area and depth to get the cubic yards and the approximate tonnage to buy for a path, driveway or drainage bed.

From area to tons
First the volume: cubic feet = area (sq ft) × depth (in) ÷ 12, then ÷ 27 for cubic yards. Gravel is sold by weight, and a cubic yard of dry gravel weighs about 1.4 tons, so multiply the yards by 1.4. A 200 sq ft area at 3 inches is about 1.85 cubic yards, or roughly 2.6 tons.
How deep for the job
Depth depends on use: 2–3 inches for garden paths and decorative beds, 4 inches or more for a driveway (often in layers — a coarse base under a finer top). Heavier traffic needs a deeper, compacted base. Order a little extra, since gravel settles and compacts once it is spread and driven on.
Weight varies by type
The 1.4 tons-per-cubic-yard figure is an average for dry gravel. Wet gravel, crushed stone and sand weigh more; some decorative rock weighs less. When precision matters, ask your supplier for the density of the specific product — they quote it per cubic yard or per ton.
