Are you tired of the default character limit for excerpts in WordPress? Do you wish you could have more control over the length of your excerpts, allowing them to dynamically adjust based on the content of each individual post? If so, you’re in luck. In this article, we will guide you through the process of creating a dynamic custom length excerpt for your WordPress website. Say goodbye to manually trimming your excerpts and hello to a more flexible and engaging user experience. Let’s dive in!

					function wpturbo_custom_excerpt_length( $length ) {
    return 20; // Change the number to your desired length
add_filter( 'excerpt_length', 'wpturbo_custom_excerpt_length' );

The code snippet provided allows you to create a dynamic custom length for the excerpt in WordPress. This means that you can define the number of words you want to display in the excerpt, rather than relying on the default WordPress excerpt length.

To begin, we define a new function called wpturbo_custom_excerpt_length() that takes a parameter $length. This parameter represents the default length of the excerpt in WordPress. In our example, we have set the length to 20, but you can change the number to your desired length.

Inside the function, we use the return statement to specify the length we want for the excerpt. In this case, we are returning the value of 20.

Next, we use the add_filter() function to hook our custom length function into the excerpt_length filter. This filter allows us to modify the excerpt length before it is displayed. By adding our function wpturbo_custom_excerpt_length as a filter to excerpt_length, we are telling WordPress to use our custom length instead of the default length.

Once the code snippet is added to your theme’s functions.php file or a custom plugin, the excerpt length on your website will be dynamically set to the value specified in the wpturbo_custom_excerpt_length function.

This code snippet provides a simple and effective way to customize the length of the excerpt in WordPress without needing to modify any core files or use additional plugins.
