How to find out current font used in my Emacs?

Solution 1:

In my version of Emacs, I can get the information by entering M-x describe-font.

Solution 2:

Different fonts can be used for different characters and different parts of the buffer. For a given character, you can find out which font was used by moving point to that character than then doing C-u C-x = which will give you all kinds of information about that position in the buffer, including which font was used for it.

Solution 3:

You can just evaluate

(face-attribute 'default :font)

To evaluate a sexp, do M-:, type/paste the above sexp in there and hit enter.

Solution 4:

Place cursor on text which you want to customize and run M-x describe-face.

It will give you information how this font was set, i.e. markdown-pre-face. You can then see that it inhertis from markdown-code-face which inherits from fixed-pitch.

And this is how you can set it:

(set-face-attribute 'default nil
                    :family "Source Code Pro"
                    :height 130
                    :weight 'normal
                    :width 'normal)
(copy-face 'default 'fixed-pitch)

Restart Emacs after setting it.
