Alright, so I got curious the other day about Conor McGregor, specifically his actual size. You see him on screen, hear all the talk, but sometimes you just gotta check the numbers yourself, you know?

First thing I did was jump online. Just typed in the basic stuff, looking for his height. Wasn’t too hard, actually. Most places seemed to agree on it.
- Found it listed pretty consistently.
- Came out to 5 foot 9 inches. Or about 175 centimeters if you use that system.
Okay, height sorted. Seemed reasonable enough. Then I started digging into his weight. Now, this is where it got a bit more interesting.
Figuring Out the Weight
Unlike height, his weight isn’t just one fixed number. Makes sense, right? Boxing, MMA, these guys cut weight or bulk up for different fights. So, I couldn’t just find one weight for McGregor.
I had to look at the weight classes he fights in. That told the real story.
- Featherweight: This was his initial stomping ground in the UFC. The limit here is 145 pounds (around 66 kg). Had to be super lean for this.
- Lightweight: He moved up to this class, became champ-champ. This limit is 155 pounds (around 70 kg). Still gotta cut, but maybe a bit more comfortable.
- Welterweight: He’s even fought up here a few times. This division goes up to 170 pounds (around 77 kg). Looked noticeably bigger in those fights.
So, yeah. His weight really jumps around depending on who he’s fighting and what division it’s in. It’s not like asking about a regular dude’s weight. His ‘walk-around’ weight is probably different again, maybe somewhere above lightweight, but the fighting weights are what people usually talk about.
Took a bit of looking around, comparing different sources, but piecing together the weight classes gave me the full picture. It’s kinda wild how much they can change their bodies for this sport. Anyway, that’s what I found out when I looked into it.
