You can (in V7, at least) also use Rasterize[.., "RasterSize"],
although you have to be careful about the various XXXPadding options
to Graphics.
In[130]:= r1 = Graphics[Rectangle[{0, 0}, {1, 10}]];
In[131]:= r2 = Graphics[Rectangle[{0, 0}, {1, 2}]];
In[132]:= Rasterize[r1, "RasterSize"]
Out[132]= {46, 432}
In[133]:= Rasterize[Show[r1, ImagePadding -> 0, PlotRangePadding ->
0], "RasterSize"]
Out[133]= {43, 432}
In[134]:= Rasterize[Show[r2, ImagePadding -> 0, PlotRangePadding ->
0], "RasterSize"]
Out[134]= {216, 432}
This should generally be more robust than most other methods I can
think of, though a bit slower than some other methods, since it has to
ask the frontend for information about the rendered result instead of
using information available to the kernel. The kernel has no idea
about things like font metrics and so this is probably a better
approach if you're interested in (styled) text.
