#4 Mike Tyson is Only 5′ 10″ Tall
Mike Tyson is only 5 feet and 10 inches tall although in his fights his height was always given as between 5′ 11″ and 6 feet tall. What is for certain is that he is small in height compared with most heavyweight boxers. His reach of 71″ is also short for a heavyweight boxer and he actually studied the boxing techniques of other small heavyweight champs such as Rocky Marciano, to help him develop his own technique and overcome bigger men in the ring.
