How Much Gravel for 50 Square Feet?

at 3 inches deep — about 25 bags (0.5 cu ft each) or 0.65 tons

Depth	Cubic yards	Cubic feet	0.5 cu ft bags	Approx. tons
2 in	0.31 yd³	8.3 ft³	17	0.43
3 in (typical)	0.46 yd³	12.5 ft³	25	0.65
4 in	0.62 yd³	16.7 ft³	34	0.86

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: 50 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.
