A hack to get a similar effect (though not the same: I have to fork my .emacs.d 
for devices with different screen sizes because I customize in 
~/.emacs.d/.emacs): 

    (add-to-list 'default-frame-alist '(height . 24))
    (add-to-list 'default-frame-alist '(width . 80))

Easier: 

(1) C-h v default-frame-alist RET
(2) select customize.
(3) experiment until you find the correct width and height :)
