Mike Mentzer’s Height Revealed in Historic Photos

When it comes to legendary bodybuilders, few have sparked as much curiosity—and controversy—as Mike Mentzer.
Known for his philosophical mindset, Heavy Duty training system, and dense, muscular build, Mentzer left a lasting legacy in the fitness world. And one of the most common questions people still ask about him today is surprisingly simple:
How tall was Mike Mentzer, really?
Depending on the source, you’ll find different answers. Some say Mentzer was 5’8″, while others argue it was closer to 5’7″.
As a certified personal trainer and long-time student of bodybuilding, I’ve analyzed the evidence—including official listings and photo comparisons—to bring you the most accurate answer possible. Along the way, I’ll also discuss his weight range and how his stature influenced his training style.
Who Was Mike Mentzer? A Quick Background
Born in 1951 in Ephrata, Pennsylvania, Mike Mentzer rose to fame in the late 1970s as a fiercely intelligent and unconventional competitor in the bodybuilding world. He won Mr. America in 1976 and Mr. Universe in 1978 with a perfect score—a feat rarely achieved.
Mentzer stood out not only for his physique but also for his brain. He brought a philosophical, almost scientific approach to training, which ultimately became the foundation of his Heavy Duty system: short, intense, infrequent workouts focused on maximum effort and recovery.
But despite his influence, there’s one thing that’s never been entirely agreed upon: how tall he actually was.
Mike Mentzer’s Claimed Height
In various publications and promotional materials throughout his competitive years, Mentzer was listed at 5 feet 8 inches (173 cm). This is the most commonly cited height and was likely used to match the sport’s tendency to “round up” athlete stats for marketing purposes.
It’s worth noting that bodybuilders—especially during the Golden Era—often inflated their heights in magazines to appear more imposing to their competitors.
What Others Say About His Height
Some bodybuilding forums and eyewitness accounts from the 1980s suggest that Mentzer stood somewhere between 5’6.5″ and 5’7.5″, depending on posture and footwear.
More recently, bodybuilding fans have expressed skepticism about Mentzer’s height, including one Redditor who suggests that, based on this picture of him next to Lee Priest (5’3″), Mentzer may not even be 5’6″.
Still, this photo was likely taken in the late 1990s, during the height of Priest’s career (no pun intended). Mentzer would have been in his late 40s and possibly began to lose his stature.
Other variables, such as the camera angle and each man’s distance from the lens, can affect their perceived heights.
Height Comparison with Other Bodybuilders
A better way to judge bodybuilder heights is to use multiple photos from onstage comparison rounds.
In these photos, the competitors are barefoot and typically standing up straight. They are also further from the camera, reducing perceived height distortions.
Using photos from the 1980 Mr. Olympia, we can compare Mike Mentzer’s height to that of other well-documented competitors, such as Arnold Schwarzenegger.
Mike Mentzer vs. Arnold Schwarzenegger
In one of the group lineups from the 1980 Mr. Olympia, Mentzer posed side-by-side with Schwarzenegger. So, we can directly compare his height to Arnold’s, who was always billed at 6’2″.
To aid the comparison, I added horizontal green lines to mark the top of each competitor’s head (accounting for Mentzer’s more voluminous hairstyle). Then I measured the height using the vertical blue lines.
I calculated the difference between the line lengths and converted that to proportional heights.
Based on these proportions, Mentzer would be about 5’9″ if Arnold was, in fact, 6’2″ tall. However, Arnold’s height has also been contested as an exaggeration.
Assuming Mentzer was actually 5’8″, that would put Arnold at 6’1″. Click here to see Arnold’s true height.
Below is another photo of Mentzer standing behind Frank Zane, who was listed as 5’9″ tall. Mentzer appears to be just a hair shorter (if you look under the hair).
While Zane may have been slightly under 5’9″, these photos suggest that Mentzer definitely wasn’t under 5’7″, as some have claimed.
Final Verdict: Mike Mentzer’s Real Height
Considering his official height listing and visual comparisons with Arnold Schwarzenegger, Frank Zane, and other Olympia bodybuilders, I estimate Mike Mentzer’s real height was most likely over 5’7″ (170 cm) but probably under 5’8″ (173 cm).
While the 5’8″ claim isn’t far off, it’s likely rounded up to the nearest inch, as most athletes and bodybuilders do. Photographic evidence and peer comparisons suggest that he fell very close to, but just short of, that mark.
But as any seasoned lifter knows, height is just a number. What mattered more was how Mentzer carried his muscle, and he was arguably one of the most impressive physiques of his time.
How Much Did Mike Mentzer Weigh?
Height only tells part of the story. Mentzer’s weight—both onstage and in the offseason—adds important context to his physical presence.
Stage Weight (Leanest)
- At the peak of his competitive career, Mike Mentzer’s contest weight was approximately 215–225 pounds.
- For a man in the 5’8″ range, that’s an incredibly dense and muscular build.
Offseason Weight (Heaviest)
- He reportedly bulked up to 250–260 pounds in the offseason, depending on the year.
- Unlike some modern bulkers, Mentzer’s off-season physique remained relatively tight, showcasing how his shorter frame and training style allowed him to pack on mass efficiently.
This high weight-to-height ratio contributed to his famously thick, grainy look—especially through the back, shoulders, and arms.
