How much gravel does your driveway need?
Calculate driveway gravel in cubic yards and US tons using your supplier’s density.
Enter your measurements
The density field begins with an example assumption—not a certified value. Ask your supplier about stone type, compaction and moisture.
Your estimate
Enter your dimensions to see your material estimate.
Calculate first. Order with confidence.
Length × width × depth (in feet) ÷ 27 = cubic yards. Apply extra-material and compaction allowances; multiply cubic yards by supplier tons/yd³ for US short tons.
Results are estimates, not a substitute for checking on-site dimensions, local requirements, packaging labels, or supplier specifications. Cost fields do not include delivery, taxes or labor unless you incorporate them into your entered price.
Understand the calculationsKnow what is included
Volume conversions use 27 cubic feet per cubic yard. Concrete bag-yield presets come from the QUIKRETE Concrete Mix No. 1101 data sheet. Gravel bulk-density values are editable examples—not universal constants.

How many tons of gravel do I need for my driveway?
First calculate cubic yards from area and depth. Then multiply by the supplier’s tons-per-cubic-yard figure for that specific gravel.
Does gravel have one standard density?
No. Aggregate grading, rock type, moisture and compaction all affect bulk density. Confirm the value before ordering by weight.
Does the calculator include compaction?
Yes. You can edit a separate compaction allowance and an extra-material allowance. Both are planning assumptions, not structural specifications.
