How to change font size in emacs?

I download emacs with 'sudo apt-get install emacs'. When I run emacs, I see emacs with too big fonts. I don't know why the default setup to have normal font size in emacs. How can I do that?

The temporary solution

You can press C-x C-+ and C-x C-- to increase or decrease the buffer text size.

The permanent solution

Put the following in your .emacs-file:

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

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

A slightly different way to do the same thing, by setting botht the font and size in one go, again in the .emacs file. If you want to use a differing font check it exists first or you will get an error message.

(set-default-font "Monospace-12")

You can also put the desired font size into ~/.Xresources:

Emacs.default.attributeHeight: 94

as in .

It will be read on the next session startup. To get those settings in the current session, you can do xrdb -merge ~/.Xresources.
