If you write real small a small one might sute you.. if you have a good space or are willing to make the room I would get one of the 12x9's, especaly if you are use to paining on canvase.. closer to a 1 to 1 ratio to the screen helps.. unless your hand motions are small and not fluid. Ei, like the mouse alot and really in to 3d and not much other art.
