 Hi @justinahinon, welcome to WordPress Trac! Thanks for the ticket.

 There is a [https://www.php.net/manual/en/function.filesize.php
 filesize()] PHP function that WordPress itself uses to
 [source:tags/5.2.1/src/wp-includes/media.php?marks=3269-3282#L3257 display
 the size of files in Media Library].

 You can use it to get the file size in bytes, e.g. `7358`:
 {{{
 $file = get_attached_file( $attachment_id );
 echo filesize( $file ); // size in bytes, e.g.
 }}}

 Or combine it with `size_format()` to get a human-readable string, e.g. `7
 KB`:
 {{{
 $file = get_attached_file( $attachment_id );
 echo size_format( filesize( $file ) );
 }}}
