Tyson (during the prime of his boxing career) stood just slightly over 5 feet 10 inches -- he has lost a little bit of height over the years, which generally happens with aging.
Tyson is also older nowadays and he was quite over weight before which also affect the height - afterwards aswell.
He's 5'10, I've seen him at a airport and I'm 5'10. We were eye to eye. (almost, I couldn't get very close to him). Also an aside, Arnold Schwarzenegger is also far shorter than you'd think. Saw him at the Arnold Classic thinking he'd be 6'5, he's barely taller than me.
I took this pic at a fight in Kissimmee, FL. [url]http://i.imgur.com/9PpYxkG.jpg[/url] To the left is my brother standing right next to Tyson. My brother is 6 ft tall exactly. As he stood in 2013, there is no way Tyson was 5' 11. Time/date stamped on image. . .
