Gravel for a Driveway

Describe the gravel layer you have chosen, then confirm the supplier’s purchasing unit.

Enter the measurements and product details, then calculate.

These tools estimate material quantities from dimensions you choose. They do not specify structural depth or load capacity.

Measure the area that will receive gravel

Break the driveway into non-overlapping rectangles and exclude existing islands or surfaces that will not receive this layer. A single bounding rectangle can include more ground than the material will cover. Keep each area named so it can be checked against your measurements.

Enter the depth already chosen for the project. This calculator does not recommend a driveway depth, assess vehicle loads or apply a generic compaction adjustment.

Example with an uncovered end section

An illustrative driveway footprint is 12 m long and 3 m wide, with a 2 m by 1 m rectangular notch at one end left uncovered. Enter the included parts as a 10 m by 3 m rectangle and a 2 m by 2 m rectangle. Their total is 34 m². At a user-selected depth of 0.1 m, net volume is 3.4 m³. A chosen 5% allowance gives 3.57 m³.

((12 × 3) − (2 × 1)) × 0.1 × 1.05 = 3.57 m³.

Leave weight unknown until density is known

The 3.57 m³ result is valid without a density. If the supplier quotes a mass, ask for an appropriate density and the basis it describes. Do not assume that this volume equals 3.57 tonnes. If a mass is calculated, select the exact unit used by the supplier: kilograms, metric tonnes or US short tons.

Review the order as a material specification

Keep the gravel description, entered depth, allowance and density basis with the project. A separate layer of another material belongs on another line even when it covers the same footprint.

The calculated volume does not include an unknown delivery minimum or supplier rounding increment. Confirm those purchasing details before turning the estimate into an actual order.

Frequently asked questions

Does PackLedge account for compacted depth automatically?

No. It uses the dimensions and material basis you enter. Confirm how your selected specification and supplier quantities relate before comparing them.
