The JP section of The Winston Effect labels their full scale rex sculpt to be 20ft tall on p.168 and the collector's card's state that the rex is 46ft in length: here The Stan Winston sculpt was also what was used to mold the skins they stuck over the animatornic. Since the skins for their animatronic hang tightly to the robotics beneath, there would be a very small differentiation between the scult size and animatronic size, which in turn would equal the animtronic within the film; within a few inches at the most.
