Okay, so I got curious about Conor McGregor’s size the other day. You see him all over the place, right? Big personality. But I started wondering, how tall is he really? And what’s his actual weight when he’s not cutting down for a fight?

My first step, naturally, was just hitting up the search engines. Typed in the usual stuff, ‘mcgregor height and weight’. Plenty of results popped up straight away. Sports sites, news articles, fan pages, the whole lot. Seemed pretty straightforward at first glance, most places quoting similar numbers.
Digging a Bit Deeper
But then I started noticing slight differences. Some sites listed him as 5’9″, others maybe 5’8″. It’s not a massive deal, but it got me thinking. The weight thing was even more varied. Of course, that made sense because the guy fought in different weight classes. Featherweight, lightweight, even welterweight.
So, I decided to look a bit closer. I specifically searched for official UFC stats, like the tale of the tape graphics they show before the fights. I figured those would be the most accurate, at least for height. I also tried looking for weigh-in photos and videos from different points in his career. You can kinda compare him to Dana White or Joe Rogan standing nearby sometimes, though that’s not exactly scientific, haha.
Sorting Through the Numbers
Finding consistent weigh-in info was interesting. You could really see the difference.
- Featherweight fights: I found records showing him hitting that 145 lbs mark dead on. Man, he looked seriously drawn out making that weight sometimes.
- Lightweight title runs: Then you see the weigh-ins for 155 lbs. He definitely looked healthier, more filled out around that weight. Seemed like his more ‘natural’ class for a while.
- Welterweight adventures: And then there were those fights at 170 lbs. He came in under the limit, I think around 168 lbs for the Diaz fights maybe? Clearly bigger, but it wasn’t his usual division.
For height, most official sources and the UFC itself seem to consistently list him as 5 feet 9 inches (around 175 cm). That seemed to be the most reliable figure I could nail down after looking through different pre-fight stats.
Final Thoughts
So yeah, after spending a bit of time clicking around and comparing stuff, I settled on 5’9″ for the height. The weight, though, it really just depends on when you’re asking. He wasn’t just one weight; he was 145, 155, or 170 depending on the fight camp. It’s kind of wild how much these athletes manipulate their weight for competition. It’s not just a single number you can pin on them easily. Took a bit more digging than I initially expected just to get the full picture.
