apply_filters( 'admin_post_thumbnail_size', string|int[] $size, int $thumbnail_id, WP_Post $post )

Filters the size used to display the post thumbnail image in the ‘Featured image’ meta box.


Note: When a theme adds ‘post-thumbnail’ support, a special ‘post-thumbnail’ image size is registered, which differs from the ‘thumbnail’ image size managed via the Settings > Media screen.
