How it’s calculated

Volume in cubic feet is length × width × depth (in inches ÷ 12); ÷ 27 gives cubic yards.

Most gravel and crushed stone weighs about 1.4 tons per cubic yard (roughly 1.3 to 1.5 depending on the stone).
Before you buy
Order 5 to 10% extra: gravel settles and compacts.
A driveway usually needs a compacted base layer of larger stone under the top layer.
Landscape fabric under paths and patios helps keep weeds down.
