Hi Victor,
I am guessing that you are using a Bristle tip brush. For those brush types size jitter is not an available option. The size of the mark is determined by the deformation of the tip with pressure. This is the case for all 3D based brushes. (Bristle, Erodible and Airbrush)

Hope this helps,
