How Much Gravel for 150 Square Feet?

at 3 inches deep — about 75 bags (0.5 cu ft each) or 1.94 tons

Depth	Cubic yards	Cubic feet	0.5 cu ft bags	Approx. tons
2 in	0.93 yd³	25 ft³	50	1.3
3 in (typical)	1.39 yd³	37.5 ft³	75	1.94
4 in	1.85 yd³	50 ft³	100	2.59

Walkways and decorative areas need 2–3 inches of gravel; driveways need 4 inches or more, usually in two compacted layers over a base. Gravel weighs about 1.4 tons per cubic yard.

The math: 150 sq ft × depth in feet ÷ 27 = cubic yards. One cubic yard of gravel covers 162 sq ft at 2" · 108 sq ft at 3" · 81 sq ft at 4".

For driveways, order crushed stone with fines (e.g. #57 over a crusher-run base) rather than round pea gravel, which never locks in place.
