How to use this driveway gravel calculator
Gravel suppliers may quote by cubic yard or by US short ton. The correct order depends on measured area, desired compacted depth and the bulk density of the stone. Use your quarry or supplier's figure for final pricing.
Step-by-step instructions
- Measure the driveway area in feet.
- Set the finished gravel thickness in inches.
- Use your material supplier's density and pricing if available.
Calculation formula
Important assumptions and limitations
Rectangular, even-depth coverage. A compaction multiplier approximates extra loose material; base preparation, drainage and load-bearing design are not calculated.
For material orders, confirm package yields, stock sizes and installation instructions with the actual manufacturer or supplier. Your building department determines the applicable local code; a quantity estimator is not a structural design or permit approval.
Frequently asked questions
How many tons are in one cubic yard of gravel?
It varies by material and moisture. The default 1.4 US short tons per cubic yard is only a planning assumption; confirm with the supplier.
What is a US short ton?
A US short ton is 2,000 pounds. It is different from a metric tonne (1,000 kilograms).
