        function resize_tag_cloud_filter($args = array()) {
                // Do changes on the lines below
                $args['smallest'] = 8;
                $args['largest']  = 18;
                $args['unit']     = 'pt';

                return $args;
        }

        add_filter('widget_tag_cloud_args', 'resize_tag_cloud_filter', 20);
?>

No config from the admin panel, do changes in the script.

Put file in the wp-content/plugins/ directory of your WordPress installation and active from the admin panel.
