    Number of comments per page

    This will use the defaults for the number of comments per page and threading. You can use custom values like this:

    // Show 25 comments per page.
    $pages = get_comment_pages_count( null, 25 );
    
    // Don't thread comments.
    $pages = get_comment_pages_count( null, null, false ); 
    
    // Show 10 comments per page, use threading.
    $pages = get_comment_pages_count( null, 10, true );

    Outside the loop

    When inside the loop, you can just pass null as the value for the $comment parameter, as shown above. You can also use the function outside the loop, but you need to pass in the array of comments. For example, you may perform a custom comment query using WP_Comment_Query:

    $args = array(
       // query args here
    );
    
    $comments_query = new WP_Comment_Query;
    $comments = $comments_query->query( $args );
    
    $pages = get_comment_pages_count( $comments );
