The detection of an orientation of a stylus relative to a touch sensitive surface is disclosed. In one example, a touch image of the stylus tip and the hand used to grasp the stylus can be captured by the touch sensor panel and analyzed to determine the stylus' orientation relative to the surface of the touch sensor panel. The analysis can include estimating the size of the user's hand, determining the distance away from the user's hand at which the stylus tip makes contact with the touch sensor panel, and determining an angle of tilt based on the estimated size of the user's hand and the distance between the tip and the user's hand.
