With an ImageSize of 144 the frame will only be 144 if ImagePadding is
zero. So what you need to do is explicitly set some image padding and
add that to the "frame size" to get your final image size:
(* padding *)
{{l, r}, {b, t}} = {{30, 30}, {30, 30}};
(* amount this adds to the size *)
{w, h} = Total /@ {{l, r}, {b, t}};
(* aspect ratio *)
aspectratio = 1./GoldenRatio;
(* frame size *)
framesize = {144, 144*aspectratio}
Plot[Sin[x], {x, 0, 10},
Frame -> True,
ImageSize -> framesize + {w, h},
ImagePadding -> {{l, r}, {b, t}}]
This is also important in dynamic plots when you are resizing -- it
allows you to keep everything a fixed size or alternatively you can
resize will scale everything correctly.
