emacs can use the apps-default emacs.geometry to comply with height and width
and position.

So you can create an apps-default Emacs file in a directory in the apps-default
search path or a directory specified by the environmental variable XAPPLRESDIR
and put in a line

emacs.geometry: widthxheight+x_position+y_position

In fact you could have -x_position or -y_position if you wanted the
position to be relative to the right or bottom of the screen.

Optionally the values in the Emacs apps-default file can be loaded into the
X11 resource database property with xrdb (during the Xsession startup sequence)
for faster loading (instead of emacs searching for the apps-default file).

You can also set frame sizes (and other properties) in emacsrc file with

(cond ((eq window-system 'x)

       (setq default-frame-alist
             '((user-position . t)
               (user-size     . t)
               (height        . 42)
               (width         . 108)
               (top           .  0)
               (left          .  0)
               (cursor-color  . "#dddd44")
               (mouse-color   . "#ffffaa")))

)

but the values for height widrth and position here are overriden (in my experience)
by the Emacs apps-default values if they are set.

    ;; let the first frame appear according to `default-frame-alist'
    (modify-frame-parameters (selected-frame) default-frame-alist)

in the init file can work around that problem.  The starting frame is a
bit special in Emacs.

Thanks for the explanation and the solution.

I had always wondered why it never seemed to behave quite as expected.

Changing the initial frame size from your .emacs is not recommended.
You'll end up with the window first being mapped at one size, and then
changing as you watch emacs start.

The recommended way is to use XResources like this:

emacs.geometry: 81x56

Experiment with the last number to get the right height.
Notice that the geometry is stated in character units.

You put XResources in a file like ~/.Xdefaults.
Use xrdb to test your changes.

Window too big

[Hendrik Boom]

When I start emacs from the menu in xcfe, it always is slightly taller 
than my screen.  I have to mouse around and make it smaller before it is 
usable.  Is there something I can put, say, in my ~/.emacs file to change 
how tall it is?

If you don't start Emacs from the menu in xcfe, but
open a terminal emulator window (e.g., xterm) and type
'emacs', you can append options that will allow you to
easily fine tune what should happen. I'm sure you can
modify the menu item to encompass such options, but at
least in the experimentation phase, and actually
every time else as well, it is faster, and more
powerful, to do it from a command interpreter. Anyway,
here are some of the options you wish to examine - do

    $ man emacs

for more!

      -fh, --fullheight
              Make the first frame as high as the screen.

      -fs, --fullscreen
              Make the first frame fullscreen.

      -fw, --fullwidth
              Make the first frame as wide as the screen.

      -mm, --maximized
              Maximize the first frame, like "-fw -fh".

Should I conclude there is no way within emacs to set the variable that 
control window size (or shoulf I say, panel size?)  There does seem to be 
a way to request full-screen mode, so there must be a way for emacs to 
determine the screen size

Or that emacs has the wrong default size for my computer, or that xcfe 
has simply decided to override them with the wrong values?

There are windows in Emacs. For example, evaluate
these:

    (split-window-vertically)
    (other-window 1)

And you can get properties as data from those, e.g.
with:

    (window-height)

But, what you are talking about seems (?) to be the
windows of the window manager of your window system
(e.g., X) and/or desktop (e.g, GNOME, KDE). And those
windows can be resized from outside of Emacs, and from
within Emacs.

Indeed, you can use, as a CLI option

    -fs, --fullscreen
            Make the first frame fullscreen.

or, in Emacs:

    (toggle-frame-fullscreen)

Perhaps what you look for is:

    frame-pixel-height
      Function: Return a FRAME's height in pixels.
    frame-pixel-width
      Function: Return FRAME's width in pixels.

?

I have no idea, but probably it is still easier to
configure this "back" to what you want in Emacs,
instead of messing with that. It is not like it is
a costly operation :)

Someone must be lying to it about how big the screen is.  When I use -fh, 
the main edit buffer just fits on the screen, the status line and the 
place you type filenames to edit does not.

I should try again with a  different window manager, see if that makes a 
difference.

Those are called the modeline and the minibuffer respectively.

Would they fit on the screen if the title bar were moved off the screen?
Maybe Emacs doesn't know how tall the title bar is. What window manager
does XFCE use, anyway?

The default is xfwm4 tho the natural flow of
configurablility runs in the opposite direction. (Or
should, at least.)

Yeah, these kinds of problems illustrate the kind of
problems you get with GUIs in general and with
"desktop environments" in particular...

My piece of advice to the OP (if he insists sticking
to a GUI Emacs) is, disable the login manager for xfce
(which is slim by default), then use ~/.xinitrc to
specify exactly what software to run.

You can check out an example here, which uses openbox
as window manager:

    http://user.it.uu.se/~embe8573/conf/.xinitrc

If that solves the problem it is either an XFCE/xfwm4
problem so then you know what not to use :)

Dunno why this happens in your case, maybe the cause is outside Emacs.

From within Emacs: of course can you control the default frame sizes.
Have a look at

   (info "(emacs) Frame Parameters")

You want to configure `default-frame-alist'.
