In the United States, the average adult man stands 5 feet 8.9 inches tall (about 5’9″), based on the most recent CDC measurements from 2021 to 2023. So any height at or above 5’10” puts a man above the national average. But “above average” means different things depending on where you live, how old you are, and how far above the mean you’re measuring.
Above Average in the U.S.
The CDC’s measured average of 68.9 inches (roughly 175 cm) comes from a nationally representative sample of men aged 20 and older. That number includes all age groups and ethnic backgrounds. If you’re 5’10” or taller, you’re above the American average. At 6’0″, you’re comfortably taller than most men you’ll encounter. At 6’2″ and above, you’re in roughly the top 5% of the male population.
Clinically, “tall stature” has a stricter definition: a height more than two standard deviations above the mean, which places someone above the 97th percentile. For adult American men, that threshold falls around 6’3″ to 6’4″. Below that line, you may be tall in everyday terms without meeting the clinical benchmark.
How It Varies by Country
What counts as above average shifts dramatically depending on geography. The tallest national averages for men belong to Finland (5’11”), Estonia (5’10.5″), Switzerland (5’10”), and Sweden (5’10”). In those countries, a man who is 5’10” blends right in, and you’d need to be closer to 6’0″ or 6’1″ to stand out.
At the other end of the spectrum, the shortest national averages include East Timor (5’2.5″), Guatemala (5’3″), Cambodia (5’3.5″), and Nepal (5’3.5″). A man who is 5’7″ would be well above average in any of those countries. The gap between the tallest and shortest nations spans nearly 20 centimeters, or about 8 inches, and that gap has actually widened for men over the past century.
Ethnicity and Background Matter
Within the U.S., average height varies by ethnic group. White and Black American men have very similar average heights, both around 178 cm (5’10”). Hispanic and Asian American men tend to be shorter on average. These differences are shaped heavily by nutrition and socioeconomic conditions across generations, not just genetics. If your family background traces to a region with lower average height, you might be “above average” for your demographic group at a height that’s closer to the overall national mean.
Age Makes a Bigger Difference Than You’d Think
Younger men are measurably taller than older men, and the difference isn’t small. Historical CDC data shows men aged 18 to 24 averaged 69.7 inches, while men 65 and older averaged 67.3 inches, a gap of 2.4 inches. Two things drive this: older adults grew up with different nutritional conditions, and people genuinely lose height as they age due to spinal compression and changes in posture.
This means a 70-year-old man standing 5’9″ is above average for his age group, while a 25-year-old at the same height is closer to the middle of the pack. If you’re comparing yourself to the men around you, the age of that group matters a lot.
People Are Getting Taller Over Time
A major study tracking height trends across 200 countries found that some populations gained dramatically over the 20th century. Iranian men born in 1996 were about 17 cm (6.7 inches) taller than those born a century earlier. South Korean men gained over 15 cm in the same period. Chinese 19-year-old boys in 2019 were 8 cm taller than their counterparts in 1985, jumping from the 150th tallest country to the 65th.
The primary driver behind these gains is childhood nutrition and living conditions, not genetic change. Populations that experienced rapid economic development and improved food access saw the biggest jumps. Conversely, countries where children still lack adequate nutrition during their school years have fallen behind their genetic potential. Research from Imperial College London found that poor nutrition during the school years accounts for a height gap of up to 20 cm across nations.
The Self-Reporting Problem
If you’re going by what men say their height is, expect some inflation. Studies comparing self-reported height to actual measured height consistently find that men add about half a centimeter (roughly a quarter inch) on average. That might sound trivial, but the gap grows with age. Men in their 20s barely round up at all (less than half a millimeter on average), while men over 70 overestimate by about 1.7 cm, or two-thirds of an inch. This means the “6-footer” you know may actually be 5’11.5″, and that effect gets more pronounced as people get older and have lost some height but still report their peak.
A Quick Reference
- 5’9″ (175 cm): Right at the U.S. average
- 5’10” to 5’11” (178–180 cm): Above average, taller than roughly 55–70% of American men
- 6’0″ to 6’1″ (183–185 cm): Noticeably tall, above roughly 80–85% of American men
- 6’2″ to 6’3″ (188–190 cm): Top 5% range
- 6’4″+ (193+ cm): Clinically tall stature territory, above the 97th percentile
These benchmarks apply to the U.S. population. In Northern Europe, each tier shifts up by about an inch. In much of South and Southeast Asia, it shifts down by three or four inches. Your frame of reference depends entirely on who you’re standing next to.
