The standard GameCube controller has a wing grip design, and was designed to fit well in the player's hands. It includes a total of eight buttons, two analog sticks, a D-pad, and an internal rumble motor. The primary analog stick was on the left, with the D-pad below it. On the right are four buttons; a large green "A" button in the center, a smaller red "B" button to the left, an "X" button to the right and a "Y" button to the top. Below those, there was a yellow "C" stick, which often serves different functions, such as controlling the camera. The Start/Pause button was located at the middle of the controller face, and the rumble motor was encased within the center of the controller.

On the top of the controller there are two analog shoulder buttons marked "L" and "R," as well as one digital button marked "Z." The "L" and "R" shoulder buttons feature both analog and digital capabilities. Each of these buttons behaves as a typical analog button until fully depressed, at which point the button "clicks" to register an additional digital signal. This method effectively serves to provide two functions per button without actually adding two separate physical buttons.
