You will use this
function the_content_word($max_char, $more_link_text = '(more...)', $stripteaser = 0, $more_file = '') {
$content = get_the_content($more_link_text, $stripteaser, $more_file);
$content = apply_filters('the_excerpt', $content);
$content = str_replace(']]>', ']]&gt;', $content);
$content = strip_tags($content);

if (strlen($_GET['post']) > 0) {
echo $content;
}
else if ((strlen($content)>$max_char) && ($espacio = strpos($content, " ", $max_char ))) {
$content = substr($content, 0, $espacio);
$content = $content;
echo $content;
echo ".";
}
else {
echo $content;
}
}

And call <?php echo the_content_word('100');?> instead of <?php the_excerpt(); ?>

It will help you or you will contact me via Skype/Gtalk: ashishkg17

 

[From the WP Codex]

function custom_excerpt_length( $length ) {
    return 20; // where '20' is whatever number of words you want
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

PHP:

Place these three lines in your theme's functions.php file.
