X and Fluxbox :: aterm fontsize

I'm trying to change the fontsize of aterm, it's too small. Is there any way to do this, besides changing the screen resolution?

Change the font name in /home/dsl/.Xdefaults.
Aterm*font: fontname

mikshaw, thanks for the answer. What are the possible fontnames? There's no xfontsel, how do I find out which fonts are available? Do I need to run something like xrdb after changing .Xdefaults? Or just open a new aterm?

Found them. Valid aliases are defined in /usr/X11R6/lib/X11/fonts/misc/fonts.alias.
