Not 100% sure I follow everything you're saying ;)

Take a look at the winfo_reqheight and winfo_reqwidth methods
you may have to call update_idletasks before calling them so
they are 'up to date'

There may also be some grid_ methods that can help, but I normally only
use pack so I'm afraid I can't be more specific
