How It Works

Calculates tons: volume in cubic yards x 1.4 tons/yard (typical for crushed stone). Add 10% for compaction.

Formula

Volume = L x W x D

10×10ft, 4in deep

100×(4/12)/27×1.4

~1.7 tons

Driveway 20×50ft, 3in

1000×(3/12)/27×1.4

~12.96 tons

1 cubic yard gravel

Typical weight

~1.4 tons

✓

Order 10% extra for compaction and waste.

✓

Different gravel types have different densities.

Not accounting for compaction

Gravel compacts 20-30% under weight. Order more than volume suggests.

Same density for all gravel types

Pea gravel: 1.25 tons/yard. Crushed limestone: 1.5 tons/yard.

10x10x(4/12)=33.3 cu ft / 27=1.23 yards x 1.4 = ~1.7 tons.

3/4 inch crushed stone. Use 3 layers: 4 inch base, 3 inch middle, 2 inch surface.
