Changing excerpt length and “read more” link is a pretty often request. Here are the function that will allow you to change both of them. Add the code to the functions.php file.

     // Change excerpt length
    function custom_excerpt_length($length) {
    return 100;
    }
    add_filter('excerpt_length', 'custom_excerpt_length');

    // Change excerpt more
    function custom_excerpt_more($more) {
    return '…';
    }
    add_filter('excerpt_more', 'custom_excerpt_more');
