Change the excerpt length of your posts

A post excerpt can appear in your RSS feed and in various other places around your blog, such as search results and archives.

By default, the excerpt length is set to 55 words. But if you want to make this shorter or longer, add the following code to functions.php and change the number “55” to your desired word count.

function custom_excerpt_length( $length ) {
return 55;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
