Hi @mcky909, and welcome to Trac.

Your issue is likely to be related with the image size post-thumbnail (see ​function reference). It might not be set properly, so WordPress falls back to the default size. Another possibility might be that the theme is using another non existing image size to output the featured image.

Hi @mcky909, and welcome to Trac.

You need to check set_post_thumbnail_size( $width, $height, $crop ); on your active theme functions.php file and update size according to your requirement. If you have a custom image field then you need to update image size using ​https://developer.wordpress.org/reference/functions/add_image_size/.

One more think that you can use ​https://wordpress.org/plugins/regenerate-thumbnails/ Plugin which help to reduce image quality/size.
