Limit Title plugin Code

[wanderer]

Greetings,

Following another thread here I was found the Limit Title plugin. I would like to go ahead and add the following code to the functions.php instead of using the widget but I'm not sure where and how to get the length I want.
What I am trying to fix is a format problem on my homepage. I managed to get the first category area uniform in length but am having problems with words wrapping below the thumbnails on posts with longer titles.

If you look here: wander-argentina.com you'll see that the first restaurant, Granix has five lines of teaser text with words going below the photo, while the others have four lines.

I would like every entry to have fours teaser lines so that it looks neater.

Can anyone tell me what the >$length) value should be and where do I insert this code?

Thanks very much!

$string = the_title('','',FALSE);

if(strlen($string) > $length)
$string = (preg_match('/^(.*)\W.*$/', substr($string, 0, $length+1), $matches) ? $matches[1] : substr($string, 0, $length)) . $replacer;

echo $string;
}
