WordPress Excerpts should be short, you know.
But when a user writes a lot, you might want to limit the number of characters for the excerpt panel: that’s where the Excerpt Character Limiter plugin comes handy!
It will basically add a character countdown to the panel titlebar, and it will truncate the text when available characters drop to zero. 
Simple but effective!
