Frequently Asked Questions
How do I calculate how much gravel I need?
Multiply length × width × depth (in feet) to get cubic feet, then divide by 27 for cubic yards. Multiply cubic yards by the material density (~1.4 for gravel) to estimate tons.
How many tons are in a cubic yard of gravel?
Roughly 1.4 tons per cubic yard for typical gravel, about 1.35 for crushed stone and sand, 1.3 for pea gravel, and 1.1 for topsoil. Wet or compacted material weighs more.
How much extra gravel should I order?
Order 10–15% more than the calculated amount. Gravel compacts and spreads unevenly, and project edges always use more than the flat math suggests - overage avoids a second delivery fee.
How deep should a gravel driveway be?
A new gravel driveway typically wants 4–6 inches over a compacted base; a top-up layer on an existing drive is usually 2–3 inches.
