How to Add a Character Counter to the WordPress Excerpt Box
If you’re a regular reader here on the WPMU DEV Blog, you may have noticed a few changes lately, namely our site design.
Our blog homepage is now a colorful collection of our most recent articles, complete with custom illustrations drawn by our talented design team. We’ve ditched sidebars and other distractions to improve the reading experience. We hope you like it.

Today, I’m going to show you how to add a character counter to the excerpt meta box in the backend of WordPress.
Adding a Character Counter to Excerpts

Why Would You Need a Character Counter?
Many themes have a specific requirement for how long excerpts should be. If you want your excerpts to display nicely without being cut off mid-sentence, having a character counter allows you to ensure your excerpt length is under a certain number of characters.
For sites like ours, having a character counter is certainly a useful feature.
