Then we have to dig into this further. Let's stick to this simple
example (where `enlarged-font-name' is just yours):
(defun enlarged-font-name (fontname frame increment)
"FONTNAME, after enlarging font size of FRAME by INCREMENT.
FONTNAME is the font of FRAME."
(when (query-fontset fontname)
(let ((ascii (assq 'ascii (aref (fontset-info fontname frame) 2))))
(when ascii (setq fontname (nth 2 ascii)))))
(let ((xlfd-fields (x-decompose-font-name fontname)))
(unless xlfd-fields (error "Cannot decompose font name"))
(let ((new-size (+ (string-to-number
(aref xlfd-fields xlfd-regexp-pixelsize-subnum))
increment)))
(unless (> new-size 0) (signal 'font-too-small (list new-size)))
(aset xlfd-fields xlfd-regexp-pixelsize-subnum
(number-to-string new-size)))
;; Set point size & width to "*", so frame width adjusts to new font
(aset xlfd-fields xlfd-regexp-pointsize-subnum "*")
(aset xlfd-fields xlfd-regexp-avgwidth-subnum "*")
(x-compose-font-name xlfd-fields)))
(defun enlarge-font-by (increment)
(let* ((old-size (cons (frame-width) (frame-height)))
(old-pixel-size (cons (frame-pixel-width) (frame-pixel-height)))
(old-font (cdr (assq 'font (frame-parameters (selected-frame)))))
(new-font (enlarged-font-name old-font (selected-frame) increment)))
(modify-frame-parameters (selected-frame) (list (cons 'font new-font)))
(sit-for 0)
(with-current-buffer (get-buffer-create "*temp*")
(goto-char (point-max))
(insert (format "%s %s %s ->\n%s %s %s\n\n"
old-font old-size old-pixel-size new-font
(cons (frame-width) (frame-height))
(cons (frame-pixel-width) (frame-pixel-height)))))))
;; (eval-buffer)
;; (enlarge-font-by 4)
;; (enlarge-font-by -4)
;; (enlarge-font-by -4)
;; (enlarge-font-by 0)
;; (enlarge-font-by 4)
With emacs -Q evaluating the commented out rows in sequence gets me in *temp*:
-outline-Courier New-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1 (80 . 38)
(672 . 608) ->
-outline-Courier New-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1 (80 . 38)
(836 . 760)
-outline-Courier New-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1 (80 . 38)
(836 . 760) ->
-outline-Courier New-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1 (80 . 38)
(672 . 608)

The sit-for is needed for getting the right new pixel values, the
resizing effect is the same when I comment it out. What do you get
here?
