The dimensions for me are always a function of the aspect ratio. I always use the aspect ratio that I deem works best with that particular image, not what the camera manufacturer decided it should be, nor what the paper manufacturer decided.
I always use mats for framed photos. In general, the total area of the mat approximates the total image area.
