Calculate gravel volume and weight needed

How Gravel Calculation Works

Formula

Volume = Length × Width × Depth; Tons = Cubic Yards × 1.4

  1. 1Enter the length and width of the area in feet.
  2. 2Enter the desired depth of gravel in inches.
  3. 3The calculator converts depth to feet and computes cubic feet.
  4. 4Cubic feet are converted to cubic yards (divide by 27).
  5. 5Weight in tons is estimated using average density of 1.4 tons per cubic yard.

Frequently Asked Questions

How deep should gravel be for a driveway?

A standard gravel driveway needs 4-6 inches of gravel. Use larger stone (2-3 inches) for the base and smaller stone (3/4 inch) for the top layer.

How much does a cubic yard of gravel weigh?

Most gravel weighs about 1.4 tons (2,800 lbs) per cubic yard. This varies by type: pea gravel is lighter (~1.35 t/cy) while crushed stone is heavier (~1.5 t/cy).

How much extra should I order?

Order 10% more than calculated to account for compaction, spreading losses, and uneven ground. Gravel compacts about 10-15% after settling.
