How can I adjust the default length of an excerpt in WordPress?

[Devin Williams]

Is there any plugin or we can do it manually  to adjust the default length of an excerpt in WordPress?

[Mark Jaquith]

In WordPress, you can adjust the default length of an excerpt by using a filter hook called excerpt_length. Here’s how you can do it:

• Open the functions.php file of your WordPress theme. This file is usually located in the wp-content/themes/your-theme-name directory.
• Add the following code snippet to the functions.php file:

function custom_excerpt_length( $length ) {

return 20; //change this number to your desired length

}

add_filter (‘excerpt_length’, ‘custom_excerpt_length’, 999);

• In the above code, the custom_excerpt_length function returns the desired length of the excerpt in words (here, 20 words). You can change this number to your desired length.
• The add_filter function hooks the custom_excerpt_length function to the excerpt_length filter hook. The last argument of the add_filter function, 999, is the priority of the filter, which can be any number.
• Save the changes to the functions.php file.Once you’ve made these changes, the default length of the excerpt in your WordPress site should be adjusted according to your desired length.

How do I show an excerpt instead of the full post in WordPress?

Scrolling down, you can then select “Excerpt” in the “Post Content” section. You might also be able to enable post excerpts in these areas if your theme has a “Theme Settings” or “Post General Settings” option. Once you’ve finished, press the “Publish” option.
