Driveways typically need a deeper gravel bed than a garden path — commonly 4–6 in of base gravel topped with 2 in of finer surface stone, or 6+ in in a single layer on soft ground. Run this once per layer if you're building a two-layer driveway, using each layer's own depth and density.

Enter the driveway's length, width, and depth to calculate gravel volume, weight, and cost.

How to Use the Gravel Driveway Calculator

Enter the driveway's length and width, set a depth and density for the layer being ordered, and add a price per ton for an estimated cost.

cubic feet = length (ft) × width (ft) × (depth (in) ÷ 12)
weight = cubic feet × density (lb/ft³)

This runs the same volume-and-weight math as the standalone Gravel Calculator, sized for driveway-scale inputs and a deeper default depth — driveways generally need more gravel than a garden path or drainage bed, both because vehicle weight demands a sturdier base and because the surface layer compacts and needs occasional top-ups over the years.

Many gravel driveways are actually built in two layers: a coarser 4-6 in base for structure, topped with a thinner 2 in layer of finer, more walkable surface stone. If that's the plan, run this calculator twice — once per layer, each with its own depth and density — rather than trying to average the two into one number.

Gravel driveways also aren't a one-time purchase the way a concrete slab is; expect to add a thin top-up layer every few years as loose stone migrates to the edges and settles into the base beneath it.
