If you are using scalable (and antialiased) fonts, then use -fa [facename] -fs [facesize] on the commandline, otherwise select a bigger font using xfontsel and use something like:
Code:
xterm -fn -misc-fixed-*-*-*-*-18-*-*-*-*-*-*-*
You can also set the appropriate resources in your .Xdefaults (or .Xresources):
For non scalable (non antialiased):
Code:
xterm*font: -misc-fixed-*-*-*-*-18-*-*-*-*-*-*-*
Or for scalable and antialiased:
Code:
xterm*faceName: fixed
xterm*faceSize: 18
Make sure that you X startup scripts merge the .Xresources or .Xdefaults with:
xrdb -merge [.Xresources or .Xdefaults]
