By default a WordPress excerpt is 55 words long. There may be case where you desire a different length for your excerpt. This is easy enough to change, just pop this into your functions.php file, and of course change the number to the length you want.
add_filter('excerpt_length', 'my_excerpt_length');
function my_excerpt_length($length) {
return 20; }
