Frequently Asked Questions

How much does a cubic yard of gravel weigh?

Most gravel types weigh between 1.2 and 1.5 tons per cubic yard. Crushed stone and pea gravel average about 1.4 tons per cubic yard, while lighter river rock is closer to 1.2 tons. Always confirm with your supplier.

How deep should a gravel driveway be?

A standard residential gravel driveway needs 4-6 inches of compacted gravel. The base layer is usually 4 inches of larger crushed stone, topped with 2 inches of finer gravel. High-traffic areas may need up to 8 inches total.

What type of gravel should I use?

Crushed stone (angular edges) is best for driveways and paths because it locks together. Pea gravel (smooth, rounded) works well for walkways and drainage. River rock is decorative and good for landscaping but shifts underfoot.

How do I convert cubic yards of gravel to tons?

Multiply cubic yards by the density factor for your gravel type. Crushed stone is roughly 1.4 tons per cubic yard. Pea gravel is similar at 1.4. River rock is lighter at about 1.2 tons per cubic yard. Suppliers typically sell by the ton.
