Systems and methods are disclosed for adjusting parallax for a 3D object appearing on a display. One such method includes selecting a target 3D object, calculating an adjusted parallax position, calculating a z-axis offset based at least in part on the adjusted parallax position, adjusting a first z-axis position of the target 3D object by the z-axis offset, and rendering the target 3D object on the display at the adjusted first z-axis position. The adjusted parallax position is based at least in part on a maximum user reach, a comfortable viewing distance, and a distance between a user and the display. The z-axis offset is set to a difference between the adjusted parallax position and a parallax for a 3D object which is farthest from the user.
