What flavor of Linux are you using where this works for you? I'm running 
Ubuntu 16.04 at the moment, and I just tried the following in an 
otherwise empty directory:

    $ mkdir b
    $ find . -size 0

The directory 'b' did not show up, hence was not reporting as size 0. 
The man page for -size does not mention any special behavior for 
directories as opposed to regular files, so I would expect Linux to 
never report any directory as size 0, since they always have '.' and 
'..' entries, as you suggested.
