How Tall Is Conor McGregor? The Notorious One Measured

Conor McGregor Height and Age: The Notorious One Measured Accurately

Conor McGregor is 37 years old in 2026, standing at 5’9″ (175 cm) with a reach of 74 inches and a walk-around weight of approximately 170 lbs (77 kg). Born Conor Anthony McGregor on July 14, 1988, in Crumlin, Dublin, Ireland, he turned average physical dimensions into a $200M+ combat sports empire.

McGregor’s height sits at the middle of the lightweight and welterweight divisions—neither the tallest nor the shortest. But his ability to generate attention made size irrelevant to his earning power. He monetized personality more effectively than any fighter in combat sports history.

Quick Facts

Purse Splits

Conor McGregor negotiated the most fighter-friendly purse splits in UFC history. While standard UFC contracts pay fighters 20–30% of event revenue, McGregor’s leverage after the Mayweather fight pushed his share to an estimated 40–50% for major events.

His disclosed UFC purses tell only part of the story. PPV points, locker room bonuses, and back-end payments typically doubled or tripled the disclosed figures:

• vs. Khabib (2018): $3M disclosed, est. $50M total
• vs. Poirier II (2021): $5M disclosed, est. $22M total
• vs. Poirier III (2021): $5M disclosed, est. $20M total
• vs. Mayweather (2017): $30M disclosed, est. $100M+ total
• Est. career fight earnings: $250M+ (all combat sports)

The Mayweather fight changed McGregor’s financial trajectory permanently. The $100M+ payday gave him capital for business ventures that now generate more than his fight earnings. For comparison on how athletes build wealth outside competition, see athlete earnings breakdown.

Pay-Per-View Revenue

McGregor has headlined 6 of the top 10 highest-selling UFC PPV events in history. The Mayweather boxing match generated 4.3 million domestic PPV buys—the second-highest in combat sports history—producing over $400 million in PPV revenue alone.

His UFC PPV events consistently draw 1–2.5 million buys, compared to the UFC average of 300–500K for non-McGregor cards. That differential represents $50–100 million in additional revenue per event that exists solely because of his drawing power.

• UFC 229 (vs. Khabib): 2.4M PPV buys — UFC record
• UFC 257 (vs. Poirier II): 1.6M PPV buys
• UFC 264 (vs. Poirier III): 1.8M PPV buys
• Mayweather vs. McGregor: 4.3M PPV buys
• Est. career PPV revenue generated: $600M+ total

McGregor’s PPV drawing power created a flywheel: bigger audiences attracted bigger sponsorships, which funded his business ventures, which reduced his financial dependence on fighting. The key deal was Proper No. Twelve Irish Whiskey, which he launched in 2018 and sold a controlling stake in for a reported $600 million valuation in 2021.

How McGregor’s Age and Height Shaped His Brand Value

At 5’9″, McGregor was never physically imposing. In the featherweight division (145 lbs), he was actually on the taller side. But as he moved up to lightweight (155 lbs) and welterweight (170 lbs), he became the smaller man—a narrative he weaponized.

At 37, McGregor is now in the twilight of his fighting career but the prime of his business career. The shift from active competitor to promoter and entrepreneur mirrors the path of fighters who built lasting wealth.

• Featherweight height rank: Above average
• Lightweight height rank: Average
• Welterweight height rank: Below average
• Business ventures: Proper No. Twelve, August McGregor, Black Forge Inn, Forged Irish Stout

McGregor vs. Other Combat Sports Stars by Height

McGregor’s 5’9″ places him in the middle tier of combat sports stars:

• vs. Canelo Alvarez: 5’8″ — McGregor is 1 inch taller
• vs. Floyd Mayweather: 5’8″ — McGregor is 1 inch taller
• vs. Khabib Nurmagomedov: 5’10” — McGregor is 1 inch shorter
• vs. Jon Jones: 6’4″ — McGregor is 7 inches shorter
• vs. Dustin Poirier: 5’9″ — Same height

Height neither helped nor hurt McGregor’s financial outcome. What mattered was his ability to generate PPV buys and convert fight earnings into business equity—a path that no combat athlete before him executed as effectively.

💡 Analyst’s Take

Conor McGregor at 5’9″ and 37 years old built a $200M+ net worth through promotional genius, not physical dominance. His height became part of the underdog narrative—the smaller fighter who talked bigger than anyone in the room. That story generated the PPV numbers that funded Proper No. Twelve, his single most valuable financial asset. The whiskey brand’s $600M valuation exceeds his total fight earnings by a wide margin. McGregor proves that in combat sports, the ability to sell a fight matters more than the ability to win one—and he monetized that principle more effectively than any fighter in history. At 37, his fighting value is declining, but his brand value is still compounding.
