I think part of the problem is that the font used on the X11 device is
Helvetica and the default font for Windows is Arial.  The default point
size is 12 in both cases, but just because two fonts have the same
nominal point size does not mean that they physically are the same size.
It should theoretically be possible to set yourself up with either
Helvetica on Windows or Arial on Linux, but I don't know of a (free)
source for such fonts.
