Conor McGregor's Real Height Explained
Conor McGregor stands at 5'8.5" (174 cm) barefoot, according to CelebHeights{rel="nofollow noopener" target="_blank"}, while the UFC officially lists him at 5'9" (175 cm). That half-inch discrepancy is common in combat sports, where promotions often round up fighter measurements. Either way, McGregor sits right around the average American male height of 5'9".
What's remarkable about McGregor's career is how he competed — and dominated — across multiple weight classes with this relatively average frame. He won the UFC featherweight title at 145 lbs, then moved up to capture the lightweight belt at 155 lbs, becoming the first fighter in UFC history to hold titles in two weight classes simultaneously. He even fought at welterweight (170 lbs), giving up significant size to larger opponents.
McGregor's reach of 74 inches is notably long for his height, giving him a functional advantage in standup exchanges that his raw height doesn't suggest. That wingspan, combined with his precision left hand and mastery of distance management, made him far more dangerous than his stature might imply on paper.
The Height Debate: What Does McGregor Really Measure?
The half-inch gap between McGregor's CelebHeights listing (5'8.5") and his UFC profile (5'9") is minor, but fight fans have debated it nonetheless. During UFC face-offs, McGregor has appeared notably shorter than fighters listed at similar heights, which has fueled speculation that 5'8.5" may be more accurate.
At UFC weigh-ins and press conferences — where fighters stand barefoot and side by side — McGregor's actual stature becomes clearer. He appeared visibly shorter than Dustin Poirier (listed at 5'9") in their trilogy of fights, and was noticeably smaller than Nate Diaz (listed at 6'0") in their famous pair of bouts. Against Floyd Mayweather (5'7") in their 2017 boxing match, McGregor had a clear height advantage of about 1.5 inches.
McGregor himself has never seemed concerned with the debate. His confidence and self-promotion have always been larger than any physical measurement. As he famously said during his rise to stardom, the size of the fighter matters far less than the size of the fight in the fighter.

Conor McGregor: Height in Context
McGregor's 5'8.5" frame carried one of the most lucrative careers in combat sports history. Born in Crumlin, Dublin, Ireland, he rose from collecting welfare checks to becoming the highest-paid MMA fighter ever. His Proper No. Twelve Irish whiskey brand sold for approximately $600 million, making him one of the wealthiest athletes in the world regardless of sport.
In the UFC's lightweight division (155 lbs), McGregor's height was fairly standard. Most lightweights range from about 5'7" to 5'10", making his 5'8.5" perfectly competitive. Where his stature became a talking point was at featherweight (145 lbs), where his cut to make weight was brutal but gave him a noticeable size advantage over shorter opponents. At welterweight (170 lbs), the opposite was true — he was often undersized against naturally bigger fighters.
The 2017 crossover boxing match against Floyd Mayweather put McGregor's frame in a different context. In boxing, reach and height are measured more precisely, and McGregor's 74-inch reach was longer than Mayweather's 72 inches. Combined with his 1.5-inch height advantage, McGregor had measurable physical edges — but boxing is a skill sport, and Mayweather's 50-0 record spoke to a lifetime of mastering the sweet science.
More recently, Jake Paul (5'11.5") and Logan Paul (6'1.5") have entered the combat sports space, and both would have a noticeable height advantage over McGregor. Whether McGregor fights again remains one of the biggest questions in MMA, but at 5'8.5" and 170 lbs, he still carries the physical tools that made him a two-division champion.
