Armand,
I don't think that's quite doing what you think. Compare these plots to
see why:
{{l, r}, {b, t}} = {{30, 30}, {30, 30}};
{w, h} = Total /@ {{l, r}, {b, t}};
aspectRatio = 1/GoldenRatio;
framesize = 144 {1, aspectRatio};
Plot[Sin[x], {x, 0, 10}, Frame -> True,
ImageSize -> framesize + {w, h}, ImagePadding -> {{l, r}, {b, t}}]
aspectRatio = .5/GoldenRatio;
framesize = 144 {1, aspectRatio};
Plot[Sin[x], {x, 0, 10}, Frame -> True,
ImageSize -> framesize + {w, h}, ImagePadding -> {{l, r}, {b, t}}]
aspectRatio = 3/GoldenRatio;
framesize = 144 {1, aspectRatio};
Plot[Sin[x], {x, 0, 10}, Frame -> True,
ImageSize -> framesize + {w, h}, ImagePadding -> {{l, r}, {b, t}}]
