How the Gravel Calculator Works

This gravel calculator converts your area dimensions and depth into volume and weight. It multiplies length by width by depth (converted from inches to feet) to get cubic feet, then divides by 27 to convert to cubic yards — the standard unit for bulk material orders. Weight is calculated by multiplying cubic yards by the tons-per-yard for your chosen gravel type. Crushed stone averages 1.4 US tons per cubic yard; pea gravel and river rock are slightly lighter at 1.35 tons; dense limestone runs about 1.45 tons. Always add 10% to account for compaction and settling, especially for driveways. Metric tonnes are provided for international reference (1 US ton = 0.907 metric tonnes).

Frequently Asked Questions

How many cubic yards of gravel do I need?
Multiply length × width × depth (in feet), divide by 27 to get cubic yards. Add 10% for compaction.
How deep should gravel be for a driveway?
4–6 inches of compacted gravel is recommended for residential driveways. Use a 4-inch base of larger stone topped with 2 inches of pea gravel.
How much does a yard of gravel weigh?
Approximately 1.4 US tons (2,800 lbs) for crushed stone. Lighter stone types average 1.35 tons per cubic yard.
How much gravel do I need for a 10×10 area?
A 10×10 area at 4-inch depth = 1.23 cubic yards ≈ 1.7 tons. At 6 inches = 1.85 cubic yards ≈ 2.6 tons.
