Gravel calculator
Estimate gravel for driveways, paths or pads. Returns cubic yards, tons and cost.
Inputs
The formula
cu yd = (L × W × depth/12) ÷ 27. Tons = cu yd × 1.4 (typical gravel).
Worked example
30 × 10 ft × 4" = 3.7 cu yd ≈ 5.2 tons.
Frequently asked
›How many tons of gravel in a cubic yard?
Most landscape gravel is 1.3–1.5 tons/yd³; we use 1.4 as a safe average.
›How thick should a gravel driveway be?
4–6" over a compacted base is standard; heavy vehicles need more.
