Perspective of first player VR character

The camera makes my character feel way too tall? What do I need to adjust so the height feels normal.
Right now for example, when I hit play, I see the tops of the trees and my feet don’t feel like they are on the ground.

I detached the camera rig from the VRTK and then could move it up and down.
