Gravel Calculator

A typical driveway needs 3-4 inches of gravel depth. Multiply the length by the width by the depth (converted to feet), divide by 27 for cubic yards, then multiply by ~1.35 for tons.

Gravel density varies by type. Pea gravel is about 1.4 t/m³ (2,350 lb/yd³), crushed stone about 1.5 t/m³ (2,500 lb/yd³), and dense-graded aggregate about 1.7 t/m³ (2,850 lb/yd³).

For a pedestrian path, 2-3 inches of gravel on a well-compacted base is sufficient. For a driveway with light vehicle traffic, use 4 inches. For heavy vehicles, 6 inches or more is recommended.

Approximately 1.35 short tons (US) per cubic yard for standard crushed stone or gravel. This varies based on the type and moisture content of the gravel.

One ton of gravel covers approximately 100 square feet at 2 inches deep, or 50 square feet at 4 inches deep.

Crushed stone (#57 or #411) is the most common driveway gravel. It compacts well, drains properly, and provides a stable driving surface. Pea gravel is used for decorative paths but does not compact.
