Gravel Calculator
Estimate gravel in cubic yards and tons from the area and depth. The default weight is 1.4 tons per cubic yard.
Use it before you order a path or driveway base, when you need tons and yards.

How we calculated this
The area and depth become cubic yards. Tons equal cubic yards times the density you enter. A common planning density for gravel is 1.4 tons per cubic yard.
What does this mean?
You need about 6.22 tons, which is 4.44 cubic yards at this depth.

How the estimate is calculated
Yards come from the area and the depth in inches.
Tons are yards times the density. Edit the density if your supplier prints a different weight.
Gravel weight
Tons = length × width × (depth ÷ 12) ÷ 27 × tons per cubic yard.
Example
- Measure the driveway or path in feet.
- Choose a depth. Two to four inches is a common top-up range.
- Order by the ton or the yard, whichever the supplier uses.
With the numbers filled in on this page, the estimate is 6.22 tons.
What changes the result
Density
Wet stone and crushed rock do not weigh the same. 1.4 tons per yard is a planning default.
Compaction
Gravel settles. A finished depth of 3 inches may need more than 3 inches loose.
Coverage
This is volume, not a landscape design.
Questions
How deep should gravel be?
Paths are often a couple of inches. Driveways are often thicker. Enter the depth you intend to install.
Why tons and yards?
Suppliers sell both ways. The page shows both.
Does this include edging?
No.
