How to resize a buffer so it only takes a small part of the screen?

Question

In Emacs how can I resize a buffer so it only takes a small part of the screen ?

Is there any way ?

I would like to have the src taking 70% of the screen and a file manager in the other 30%

Is it possible to have any way to make it happened when open emacs instead of inputting command after that. — Enze Chi, Oct 25 '11 at 11:17

Set width of current window on current frame to ~ 70%:

(window-resize nil (- (truncate (* 0.7 (frame-width))) (window-width)) t)

The other windows are shrunk automatically. If you want to adjust more than one it gets more difficult.

As command:

(defun window-resize-to-70-percent ()
  (interactive)
  (window-resize nil (- (truncate (* 0.7 (frame-width))) (window-width)) t))

should I type it on the mini-buffer ? – Cristiano Fontes Oct 03 '11 at 01:37

You can type it after `M-:` (`eval-expression`) or you can define it as command (I'll add this to my answer) – Michael Markert Oct 03 '11 at 17:25
Due to the existence of scroll bars and the like, `window-total-width` seems to be a better function to use – Jason Dufair Feb 05 '19 at 20:09

Use separate window-manager frames for individual buffers (by default). Automatically shrink-fit the frames to fit the buffer content.
