How to set the font size in Emacs?

Question

I also want to save the font size in my .emacs file.

Answer 1

Firefox and other programs allow you to increase and decrease the font size with C-+ and C--. I set up my .emacs so that I have that same ability by adding these lines of code:

(global-set-key [C-kp-add] 'text-scale-increase)

(global-set-key [C-kp-subtract] 'text-scale-decrease)

Answer 2

From Emacswiki, GNU Emacs 23 has a built-in key combination:

C-xC-+ and C-xC-- to increase or decrease the buffer text size

Answer 3

I've got the following in my .emacs:

(defun fontify-frame (frame)
  (set-frame-parameter frame 'font "Monospace-11"))

;; Fontify current frame
(fontify-frame nil)
;; Fontify any future frames
(push 'fontify-frame after-make-frame-functions) 

You can subsitute any font of your choosing for "Monospace-11". The set of available options is highly system-dependent. Using M-x set-default-font and looking at the tab-completions will give you some ideas. On my system, with Emacs 23 and anti-aliasing enabled, can choose system fonts by name, e.g., Monospace, Sans Serif, etc.

Answer 4

Open emacs in X11, goto menu Options, select "set default font ...", change the font size. Select "save options" in the same menu. Done.

Answer 5

This is another simple solution. Works in 24 as well

(set-default-font "Monaco 14")

Short cuts:

`C-+` increases font size
`C--` Decreases font size

Answer 6

(set-face-attribute 'default nil :height 100)

The value is in 1/10pt, so 100 will give you 10pt, etc.
