Gravel calculator
Area and depth to cubic yards and tons — crushed stone, driveway gravel, or pea gravel, with the weight shown as an honest range.
Pre-filled example: a 10 × 10 ft area at 3 inches. The tons figure uses a typical 2,800 lb/yd³ with the published 2,600–3,000 range.
Yards first, then tons
Your project defines a volume — length × width × depth. Weight is derived from it, and it moves with moisture and stone type: published construction charts list dry gravel around 2,970 lb/yd³, crushed stone at 2,700, and a government volume-to-weight table puts “stone or gravel” at 2,632 lb/yd³. That spread is why this page shows tons as a range rather than one falsely precise number.
Pea gravel estimates identically — same density band. The practical difference is shape: rounded pea gravel stays loose (paths, play areas, drainage), while angular crushed stone compacts into a stable base. If you’re building a paver base, the paver calculator sizes the base and bedding sand to the industry install spec.
