Marked resolved.

I stumbled across the documentation I was after.

For anyone looking for the same info here it is:
https://yoast.com/wordpress/plugins/seo/api/

To solve my issue I added the below in functions.php:

function yoast_trim_description( $str ) {
     return substr($str, 0, 160);
}
add_filter( 'wpseo_metadesc', 'yoast_trim_description' );

nbruley – fantastic! Worked like a dream.

Many thanks.

Hi nbruley – I’ve been searching and searching for a solution like the one you are describing. Could you re-post the PHP that has been moderated out?

Many thanks!
