Limit the Excerpt Length

Greetings,

I would like to know if there is a simple way to limit the excerpt length by words. I would like to shorten these up a bit.

You can see where I am using the Shortcodes Ultimate widget at http://clearpointmarketing.com/gerbervillage.dev

I am using three post shortcode widgets and offsetting them so that a different post displays in each box.

This is a bit time sensitive and I appreciate your help. Cheers!
