Contrary to popular belief, both the PS3 dualshock 3 (DS3) and the Xbox 360 gamepad are quite similar in size. With both controllers laid out, the dimensions of the controllers are roughly 6 x 3.5 x 2 inches. There is a misconception that the Xbox 360 controller is bigger than the PS3 controller which is false. The Xbox 360 controller however does have slightly more girth around the handle area causing you to cradle the controller instead of grasping it like the DS3.
