To set the width of the current frame:

(set-frame-width nil 150)

Or make it a command:

(defun my-set-frame-width (width)
  (interactive "nWidth: ")
  (set-frame-width nil width))

Or use commands `enlarge-frame-horizontally' and `shrink-frame-horizontally':

Or use command `fit-frame' to fit a one-window frame to its buffer:

If you want to always set the same frame to a given width:
(set-frame-width my-frame 150)

If you only know the buffer name, not the frame name, display the buffer, select
its window, and then set the selected frame's width:

(select-window (get-buffer-window my-buffer 'visible))
(set-frame-width (selected-frame) 150)
