In 4.7, go into Administer -> Settings -> Posts and you'll see a "Length of trimmed posts".
Here you can set it to 200 characters, which is probably close to 20 words.
Drupal only measures it in terms of characters (bytes), not words. The minimum is 200 characters (5.x). I'm sure that some smart person could easily write a little filter module that would count words and automatically insert a <!--Break--> after 20 words.
