I've the opposite experience with apps in general if I compare fonts 
between windows and linux. On my linux, using the same dpi, the same 
fonts look bigger and fatter than on my windows.
Event when I run a xserver on windows, with a smaller DPI than my 
windows, the fonts are bigger.

Anyway, back to lazarus, fonts defined in points should look to have the 
same size on different dpi.
Years ago I wrote that I woulf have a look to get it right for Lazarus, 
but that time didn't come :(
