How to calculate gravel
- Measure the length and width of the area in feet.
- Choose a depth — 2–3 inches for paths, 4+ inches for driveways.
- Volume = length × width × depth (in feet), divided by 27 for cubic yards.
- Multiply volume by the gravel's density to get weight in tons.
How much does a yard of gravel weigh?
Most gravel weighs roughly 1.4 tons per cubic yard, though it varies by stone type and moisture. Suppliers often sell gravel by the ton rather than by volume, so it helps to know both numbers. This calculator gives you cubic yards and an estimated weight in tons so you can order in whichever unit your supplier uses.
Frequently asked questions
How deep should gravel be for a driveway?
A gravel driveway usually needs 4–6 inches total, often in layers — a coarse base layer topped with finer gravel. For walking paths, 2–3 inches over landscape fabric is enough.
Is gravel sold by weight or volume?
Both. Bulk suppliers often price by the ton, while some sell by the cubic yard. Knowing both figures lets you compare prices and order the right amount regardless of how it's listed.
Should I add extra for compaction?
Yes — gravel settles and compacts, especially on driveways. Ordering about 10% extra is sensible, and you'll want a bit spare to top up low spots later.
