Calculate how much gravel you need in cubic yards, tons, and bags. Perfect for driveways, paths, and landscaping.
Step 1: Calculate volume. Volume (cu ft) = Length (ft) x Width (ft) x Depth (ft)
Step 2: Convert to cubic yards. Cubic yards = Cubic feet / 27
Step 3: Convert to weight. Multiply cubic yards by the density of your gravel type (typically 1.3-1.5 tons per cubic yard).
Depth recommendations: Driveways: 4-6 inches. Walkways: 2-3 inches. Landscaping beds: 2-4 inches. French drains: 12 inches.
A ton of gravel covers approximately:
2 inches deep: ~100 sq ft. 3 inches deep: ~65 sq ft. 4 inches deep: ~50 sq ft. 6 inches deep: ~35 sq ft.
These are estimates for standard gravel at ~1.4 tons per cubic yard. Actual coverage varies by material type and compaction.
