How to make urxvt fullscreen in Ubuntu 9.04?

[Duke.Augustine]

I wanna use "URxvt" Terminal, and I wanna make it fullscreen so that I can concentrate my attention to the work. But when I start urxvt, it just fits the 3/4 size of my screen. And I searched a lot on the Internet using Google, but what I got is something about fluxbox, or openbox etc. I think the results have no direct connection to my problem. So, I'd like to please someone can help me. PLZ~~~

You can add a URxvt.geometry: variable to your .Xdefaults file, to make urxvt start with a particular size. Have a look at the urxvt manpage (http://linux.die.net/man/7/urxvt) for examples of the exact syntax.
