I think that `frame-char-height' and `frame-char-width' is what you
are looking for.
I use the following to change the font without resizing the frames. This uses
only the `editable' part of the frame - without the border and menus areas.
(defun set-font-keep-size (font)
"set font to use, keep window size"
(let ((fht (* (frame-parameter nil 'height) (frame-char-height)))
(fwd (* (frame-parameter nil 'width) (frame-char-width))))
(set-default-font font)
(set-frame-value-all 'font font)
(set-frame-value-all 'height (/ fht (frame-char-height)))
(set-frame-value-all 'width (/ fwd (frame-char-width)))))
`set-frame-value-all is my function to set a value on all frames.
Ehud.
