Gravel Driveway Calculator

Measure the driveway

Measure the driveway length and average width. If it widens, narrows or curves, split it into manageable sections and add the areas. Record the measurements in feet.

Choose a planning depth

Enter the intended aggregate depth in inches. Depth is a project decision, not just a calculator input; it can depend on the existing base, traffic, drainage and aggregate type. Use project specifications or local professional guidance where appropriate.

Why gravel weight is approximate

Volume is geometric. Weight depends on bulk density, which changes with rock type, particle size, moisture and compaction. That is why the calculator asks for density and labels the tonnage as approximate.

Example

A 60 ft × 10 ft driveway at 4 inches deep has 600 square feet. Converting 4 inches to one-third of a foot gives roughly 200 cubic feet, or 7.41 cubic yards before an allowance. The tonnage depends on the selected density.

Before you order

Ask the supplier for the product’s typical bulk density or delivery basis, confirm the depth and account for the condition of the existing base. Delivery may be sold by the ton, cubic yard or truckload depending on the supplier.

These estimates are for general planning. Product specifications, site conditions, local requirements and professional recommendations should take priority where applicable.
