How to estimate gravel for your project

Gravel is usually delivered in bulk and sold by the ton, but it is measured by volume. Enter your area and depth to get cubic yards, then this calculator converts to tons so you can order by weight, plus a bag count for small top-ups.

Gravel weighs roughly 1.4 tons per cubic yard, though exact weight varies with stone size and moisture. For a driveway, plan a 3 to 4 inch depth over a compacted base; for paths and drainage, 2 to 3 inches is usually enough.

Frequently asked questions

How many tons of gravel are in a cubic yard?
Gravel runs about 1.4 tons per cubic yard on average, so a 3-yard order weighs roughly 4.2 tons. Weight shifts a little with stone size and how wet it is, so treat it as a close estimate.
How deep should gravel be for a driveway?
For a residential gravel driveway, plan 3 to 4 inches of surface gravel over a compacted crushed-stone base. Enter 4 inches above to size the top layer, and add a base calculation separately.
