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.
