Quick Summary & Key Answer

To calculate gravel, multiply length × width × depth (in feet), divide by 27 to find cubic yards, and multiply by 1.4 to convert to US tons. For example, a 12' × 50' driveway at 4 inches deep requires 7.41 cubic yards, or approximately 10.75 tons (11.8 tons with 10% compaction).

1 Cubic Yard of crushed gravel weighs approximately 2,800 lbs (1.4 tons).
Recommended gravel driveway thickness is 4 inches over a compacted sub-base.
Geotextile fabric under gravel prevents rock from sinking into subgrade soil.

Net Volume in Cubic Yards: 7.41 cu yd
Net Weight without Waste: 10.74 Tons
Standard Dump Truck Loads (12 ton cap): 1 trucks
Total Surface Area Covered: 600 sq ft

Note: Gravel compacts by 10-15% when rolled or plate-compacted. Always order a 10% safety buffer.

Driveway Gravel Selection

Crushed base with fines (D-1 or 3/4" minus) compacts into a tight hard surface that resists washboarding.
