Not all rock needs to be larger than the 3" x 3" mesh size

Gabion fill shall be hard and durable and non frost susceptible (rock or stone type) having a minimum dimension not less than 80% of the mesh opening and a maximum dimension of 8 inches.

Gabion rock fill weighs approx 2700lbs per cubic yd or 100lbs per cubic ft

Decorative square split rock face, with cheap railway ballast behind

Angular rock is the best gabion fill as it provides a good interlock and therefore less deformation of the face occurs. When using rounded river rock as gabion fill, it is recommended that you use the heavier 3/16th gabion baskets, which are less likely to deform under load. Also 3/16th wire is the preferred choice where an uniform architectural look is required.
