Joe, that one is considered 3/4 size. The full size White is even larger! I know it doesn't seem 3/4 size when sitting next to other machines. It's more that it is not as long, the light fixture takes up the full distance between head and pillar. With the larger size, there is more room under the arm.
this is the full size version
