Why gravel sells by weight

You dig by volume but buy by weight, because a loader bucket's worth of wet crushed stone and dry pea gravel fill the same space and weigh different amounts. The bridge between them is density — around 1.4 tons per cubic yard for common crushed products — which turns your carefully measured depth into the number on the invoice.

Depth choice carries more risk than any other number here: two inches looks great the day it spreads and disappears into mud by spring. Four inches minimum wherever wheels roll.

The truck-load line

A standard single-axle dump delivers about 10 tons; a small trailer tows 2. The estimate above divides your tonnage so you know whether this is one phone call or three weekend hauls.

Questions from the aisle

How much does a cubic yard of gravel weigh?

Roughly 1.4 tons for typical crushed stone — the density this calculator assumes. Pea gravel runs a touch lighter, dense crusher run heavier; the supplier's scale is final.

How deep should a gravel driveway be?

4 inches over stable soil, 6+ inches over soft ground. Driveways also want 3–4 inch stone as a base course with finer gravel on top — calculate each layer separately.

Bags or bulk?

Bulk, almost always. A half-ton pickup hauls maybe a third of a yard legally, and 0.5 cu ft bags mean forty trips to the parking lot for one yard.

Does gravel compact or settle?

Yes — crushed stone with fines compacts to near its ordered volume; rounded pea gravel settles and scatters. Order 10% extra on soft subgrade to stay level after the first winter.
