I use in my ~/.emacs
 
(setq-default tab-width 4)
(setq-default indent-tabs-mode nil)

That makes Emacs insert 4 spaces instead of a tab.

Tabs vs. Spaces
===============

   Emacs normally uses both tabs and spaces to indent lines.  If you
prefer, all indentation can be made from spaces only.  To request this,
set `indent-tabs-mode' to `nil'.  This is a per-buffer variable, so
altering the variable affects only the current buffer, but there is a
default value which you can change as well.  *Note Locals::.
