Any other hints about font size in KDE?
Are you using a higher resolution > 1024X768 I find that KDE uses too small a dpi when started via KDM which results in the fonts being too small on the screen. I get by this by changing the dpi manually in the file /etc/kde3/kdm/kdmrc in the line like this.
ServerArgsLocal=-dpi 100 -nolisten tcp
This is on Debian the file may be in a different location in whichever distro you use, this only works when using KDM to login and you may want to change the 100 to a smaller/larger number depending on how the fonts end up looking.
