I can only reiterate that it works for me.  Perhaps your window manager
is interfering somehow.  The doc string of set-frame-size says:

  (set-frame-size FRAME WIDTH HEIGHT &optional PIXELWISE)
  
  Set text size of FRAME to WIDTH by HEIGHT, measured in characters.
  Optional argument PIXELWISE non-nil means to measure in pixels.  Note:
  When ‘frame-resize-pixelwise’ is nil, some window managers may refuse to
  honor a WIDTH that is not an integer multiple of the default frame font
  width or a HEIGHT that is not an integer multiple of the default frame
  font height.

FWIW I'm using xfwm4.
