Wordpress allows configuration for setting the number of posts to be displayed whenever an index archive (the typical homepage) or other archives like category or monthly archives are displayed. This option can be configured in the Blog Pages field Reading tab under Options menu in the administration User Interface. Note that there is a separate field for configuration number of posts to be displayed for syndication (feeds).
posts_per_page is set in the method get_posts of WP_Query.
Plugin and theme authors need not access this global variable directly. Wordpress uses it internally to calculate the number of posts to be displayed.
Since the same setting is used for all archives Matt Read has developed a plugin where posts per page setting can be set for different types of archives, e.g., search, category, home, monthly, yearly, etc.

Good post. It did not have the complete answer I was looking for, but lead to it. I have this posted within my index.php prior to the loop that displays my posts. It is set in a “Recent Posts” section and my main page displays the recent 3 posts.
query_vars["posts_per_page"] = 3; $wp_query->get_posts(); ?>
Thanks for the help

Code edit to last post. This is the correct code.
query_vars["posts_per_page"] = 3; $wp_query->get_posts(); ?>
