WordPress – customize posts per page for tag, category and date archive pages

By admin on Jan 10, 2016

The following code can be used to have separate value of posts per page for various archive pages (category, tag, date, author, etc.)

add_filter('pre_option_posts_per_page', 'posts_per_page_filter');
function posts_per_page_filter() {
  if ( is_archive() ) {
    // date,tag
    if (is_date() || is_tag() ) {
      return 30;
    }
    if (is_category() ) {
      return 20;
    }
  }
  return 10; // default
}
