is there also a way to limit the char or word count when displaying the content in “full”
yes, you can limit the excerpt length by overwrite value, for example:
function custom_excerpt_length( $length ) {
return 20;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

and yes, you can also limit the content length by filters.
Read https://ww.wp.xz.cn/plugins/wp-posts-carousel/faq/ and see an example of usage: http://pastebin.com/kZs3bDh1
which file do I put the code in?
into functions.php in yours theme directory
thanks for that it works with word count – but not character count, is there a way to use character count as people entering hyperlinks and web addresses at the start of the content and making excerpt really long.
