How it works

How to calculate it

The calculator applies the values you enter to this formula:

Cubic yards = length × width × (depth ÷ 12) ÷ 27; tons = cubic yards × density.

How to use this calculator

Measure the finished gravel area.
Enter compacted depth and product density.
Use the supplier's price and tons-per-yard figure.

Worked example

A 20 × 15 ft area at 3 inches deep needs about 2.8 cubic yards, or roughly 3.9 tons at 1.4 tons per yard.

Important assumptions

Density varies by stone type, size, and moisture.
The base is level and already compacted.
Delivery, fabric, edging, and labor are excluded.

Common mistakes to avoid

Using a generic density for every stone.
Ignoring base layers and compaction.
Assuming truck capacity equals the quantity delivered.
