Frequently asked questions
Why is gravel sold by weight and not volume?
Gravel suppliers typically price and deliver by the ton rather than the cubic yard, since trucks are weighed — this calculator converts your area and depth straight into tons using a standard gravel density (about 1.4 tons per cubic yard) so you can order directly.
How deep should a gravel driveway base be?
4 inches is a common base-layer depth for a driveway; 2 inches is more typical for topping up an existing path. Depth needs vary by use and local soil conditions.
