Mike Tyson And the Difference In Size And Weight In Boxing

Mike Tyson in his younger years.

While the size and weight difference is important in boxing, it is not always the case for some exceptional boxers who have defied logic and beaten naturally bigger and taller opponents. We can take a look at Mike Tyson, for example, who is considered a small heavyweight at 5 feet 11 inches tall and 220 pounds. Tyson’s fighting weight is between 217 and 223 pounds and he took on guys who are 10 to 20 pounds heavier and several inches taller than him.


In boxing’s heavyweight division, by the way, there is no rule for weight difference as long as the boxer must weigh at least 220 pounds. But what about the boxers in the lower weight divisions? It’s a different picture in the lower weight divisions where weight rules are strictly enforced or observed. But there are few exceptional fighters who jumped from one weight division to another and dominate every weight class they have ventured.

Take a look at Manny Pacquiao, for example, who started as a professional boxer in a light flyweight division and eventually became the only boxer in history to win 12 major world titles in eight different weight divisions. We can simply ask, how did these fighters pull it off? What secret do these guys keep when they move from one weight class to another and can still dominate the game?


Mike Tyson’s pro debut was at 214 pounds when he was just 18 years old. The fight that took place on March 6, 1985, ended in a first round TKO against Hector Mercedes. That fight served as a preview of the future of the man who would later be called “Iron.” He was young, hungry, and fearless.

Mike Tyson fought his lightest weight of his career at 212 pounds, which he won by fourth round knockout against Dan Halpin on May 23, 1985. It was his third fight as a professional boxer. His heaviest weight as a pro was when he fought Brian Nielsen at 239 pounds on October 13, 2001. He won by six round TKO against a 21 pounds heavier Nielsen. The fight with Nielsen was his 52nd professional fight.

Mike Tyson as a five-foot-eleven heavyweight boxer is a rarity in boxing. But what he lacked in size and height, he made up for in speed, head movements, and proper timing. He has also topped the list of the hardest punchers in boxing history.


In boxing’s lower weight categories, Manny Pacquiao is the only fighter worthy of being compared to Tyson. They’re both knocking out guys regardless of size, height, and weight differences. They are both quick and use head movements a lot.

But aside from these similarities, there is something these two boxers share that makes it more interesting. And it’s the size of their wrist bones. Mike Tyson has a wrist bone that is the same as Pacquiao’s: 8 inches. So far, there are only three people in boxing history who have a wrist bone that measures 8 inches: Joe Louis, Mike Tyson, and Manny Pacquiao.

Is this perhaps why Mike Tyson is capable of hitting extremely hard for his size against much bigger opponents? Or what do you think?
