change excerpt length

  • Currently the excerpt length is 55 words. In which file can I change this to a different number?

    Cheers,
    Florian

  • Inside your theme’s functions.php file, write this:

    function custom_excerpt_length( $length ) {
   return 20; // you can use any integer per your requirement.
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
