The majority of Italian mobsters aren't tall guys. Castellano was often described as 6'2" or 6'3", but if you look at his booking photo from his 1985 arrest, the one where he's standing next to the height chart, he's nowhere near that.
It could have been an age thing too, as he got older (like many of us do) his posture was not as good as it was when he was younger so you would actually appear to be not as tall as you were. I never paid attention to his '85 booking photo though to see how far off from 6'2" he was.
