About Gravel Calculator
Enter length, width, and depth and get the gravel volume in cubic yards plus its weight in tons. Density defaults to 1.4 tons per cubic yard — a common figure for crushed stone — and is editable for pea gravel, river rock, or whatever your supplier quotes.
Common uses
- Order the right number of tons for a gravel driveway top-up
- Size a base layer for a shed or patio
- Convert a landscaper's cubic-yard quote into delivery tons
Example
Input
20 × 10 ft at 3 in deep, 10% waste
Output
1.85 yd³ exact → order 2.04 yd³ ≈ 2.85 tons
Limitations
- Density varies with stone type and moisture — confirm the tons-per-yard figure with your supplier
Frequently asked questions
How many tons of gravel do I need for my driveway?
Multiply length × width × depth to get cubic yards, then multiply by about 1.4 tons per yard for crushed stone. A 50×10 ft driveway topped up 2 in deep works out to about 3.1 cubic yards, or roughly 4.3 tons.
How much does a cubic yard of gravel weigh?
Crushed stone commonly weighs about 1.4 tons (2,800 lb) per cubic yard, which is this calculator's default. Actual density ranges from roughly 1.2 to 1.7 tons per yard depending on stone type, size, and moisture, so use your supplier's quoted figure.
How deep should gravel be on a driveway?
A total of 4–8 in is typical for a residential driveway, built in compacted layers, while a top-up of an existing surface may only need 1–2 in. Deeper isn't automatically better — a proper base layer matters more than extra surface stone.
Is any of my project data uploaded when I use this?
No. The area, depth, and density math runs locally in your browser; your measurements are never sent to a server or saved anywhere.
