The average male height in the US is 5 feet 9.1 inches, or approximately 175.3 centimeters, according to physical measurement data from the CDC’s National Health and Nutrition Examination Survey (NHANES). This is not a self-reported figure. The CDC sends trained health technicians to mobile examination centers to physically measure participants, which makes this data significantly more reliable than online polls or dating profile heights.
But a single national average only tells part of the story. Average height for men in the United States varies meaningfully by age group, ethnicity, and geographic region. It also has implications that go beyond simple curiosity. Understanding where American men actually land on the height spectrum shapes realistic expectations in health, fitness, and dating alike.
This guide covers the complete picture: the verified national average, how height shifts across every demographic, how American men compare globally, what the numbers mean for health, and why the difference between average and 6 feet is more significant than most people realize.
The Average Male Height in the US
The average height for men in the United States is 5 feet 9 inches (approximately 175.3 cm), according to CDC NHANES data from physical examinations conducted between 2015 and 2018. This is the most recent large-scale physically measured dataset available and remains the standard reference for US male height statistics.
To put this in context: 5’9″ (175.3 cm) means the average American man is notably shorter than many people assume. Online discussions about height often treat 5’11” or 6’0″ as a kind of baseline, but the verified data tells a different story. The true midpoint of American male height is closer to 5’9″ than most people realize.

Why Physical Measurement Matters: The CDC’s NHANES data is collected through physical examinations, not questionnaires. This is critical because when men self-report their height, they consistently round up. The difference between measured and self-reported height averages 0.5 to 1 full inch. A man who reports being 6 feet tall in a survey may measure 5’11” or even 5’10.5″ in person.
Average Height for Men by Age Group
US male height by age group shows a clear pattern. Men reach their peak height in their late teens to mid-twenties and then begin a slow but measurable decline as they age. This decline is caused by the gradual compression of spinal discs, loss of bone density, and the gradual changes in posture that come with aging.
The following data comes from CDC NHANES anthropometric measurements (2015-2018) based on physical examinations of adult men aged 20 and older:
| Age Group | Average Height (Inches) | Average Height (cm) |
|---|---|---|
| 20 to 29 (Peak Years) | 69.3 inches (5'9.3") | 176.0 cm |
| 30 to 39 | 69.6 inches (5'9.6") | 176.8 cm |
| 40 to 49 | 69.5 inches (5'9.5") | 176.5 cm |
| 50 to 59 | 69.0 inches (5'9.0") | 175.3 cm |
| 60 to 69 | 68.6 inches (5'8.6") | 174.2 cm |
| 70 to 79 | 68.1 inches (5'8.1") | 173.0 cm |
| 80 and over | 67.1 inches (5'7.1") | 170.4 cm |
Height Relative to Peak (30-39 Age Group = Baseline)
Key Insight: Men in the 30 to 39 age group actually measure slightly taller on average than men in their twenties. This likely reflects the fact that the current 30 to 39 cohort experienced better early childhood nutrition than the older cohorts measured in the same survey. The sharp decline starting in the 60s is driven by spinal compression, reduced disc hydration, and lower bone density, all of which are normal parts of aging.
US Male Height Statistics by Ethnicity
Male height statistics in the United States vary significantly across ethnic groups. These differences are driven by a combination of genetic background, generational nutrition quality, immigration patterns, and socioeconomic factors that affect childhood development. The CDC NHANES data breaks down average height by ethnic group as follows:
| Ethnic Group | Average Height | In Centimeters | vs National Avg |
|---|---|---|---|
| Non-Hispanic White | 5'10.0" (70.0 in) | 177.8 cm | +0.9" |
| Non-Hispanic Black | 5'9.3" (69.3 in) | 176.0 cm | +0.2" |
| Non-Hispanic Asian | 5'7.5" (67.5 in) | 171.5 cm | -1.6" |
| Mexican American / Hispanic | 5'6.9" (66.9 in) | 169.9 cm | -2.2" |
Source: CDC NHANES 2015-2018 anthropometric data, adults aged 20+.
These differences matter in practical terms. The 3.1-inch gap between the tallest and shortest average groups means that the significance of any given height threshold varies considerably depending on which population you are looking at. A height threshold of 5’10” would exclude only about half of Non-Hispanic White men but would exclude a far larger proportion of Hispanic and Asian American men.
Generational Trend: American men have grown taller on average over the past century due to improved childhood nutrition, healthcare, and living standards. However, this generational increase has slowed significantly since the 1980s. Many researchers believe the US has largely reached its genetic potential for height under current nutritional conditions.
How American Men Compare to the Rest of the World
The average American man at 5’9.1″ is taller than the global average of approximately 5’7″ (171 cm), but the United States does not rank among the world’s tallest countries. Data from the NCD Risk Factor Collaboration study of 65 million participants across 200 countries places the Netherlands consistently at the top of global male height rankings.
| Country | Average Male Height | vs US Average |
|---|---|---|
| 🇳🇱 Netherlands | 6'0.4" (183.8 cm) | +3.3" taller |
| 🇩🇰 Denmark | 5'11.5" (181.9 cm) | +2.4" taller |
| 🇬🇧 United Kingdom | 5'10.0" (177.8 cm) | +0.9" taller |
| 🇨🇦 Canada | 5'10.0" (177.8 cm) | +0.9" taller |
| 🇺🇸 United States | 5'9.1" (175.3 cm) | Baseline |
| 🇧🇷 Brazil | 5'8.5" (174.0 cm) | -0.6" shorter |
| 🇨🇳 China | 5'8.0" (172.7 cm) | -1.1" shorter |
| 🇮🇳 India | 5'5.0" (165.3 cm) | -4.1" shorter |
| 🇵🇭 Philippines | 5'4.0" (162.6 cm) | -5.1" shorter |
The practical implication of this global variation is significant. A height threshold that seems modest in the Netherlands may eliminate a very large percentage of men in countries like India or the Philippines. When people discuss average American man height in a dating context, the comparison point that matters is the US population, not the global one.
Height Distribution: What Percentage of Men Are Each Height?
Male height in the US follows a normal (bell curve) distribution centered around the 5’9″ average. This means that most men cluster near the middle, with progressively fewer men at the extremes in either direction. Here is how the height distribution American men fall breaks down in practice:
| Height | % of Men AT or Above This Height | Approximately 1 in... |
|---|---|---|
| 5'5" (165 cm) | ~93% | ~1.1 men |
| 5'7" (170 cm) | ~75% | ~1.3 men |
| 5'9.1" (175 cm) AVG | ~50% | 2 men |
| 5'11" (180 cm) | ~30% | ~3.3 men |
| 6'0" (183 cm) | ~14.5% | ~7 men |
| 6'2" (188 cm) | ~3.2% | ~31 men |
| 6'4" (193 cm) | ~1.1% | ~91 men |
For a deeper breakdown of the 6-foot threshold specifically, including how these percentages change by age and ethnicity, see our dedicated guide on what percentage of American men are over 6 feet tall.
The 6-Foot Reality Check: Only about 14.5% of American men are 6 feet or taller. That means roughly 85.5 out of every 100 men you encounter do not reach 6 feet. A 6-foot height minimum is not a modest preference. It is a filter that immediately removes most of the male population from consideration.
Why Self-Reported Height Is Almost Always Wrong
This is one of the most practically important sections in this entire article, particularly for anyone using height data in a dating context. Research consistently shows that men overestimate their own height when asked to self-report, typically by 0.5 to 1 inch.
Multiple studies have compared self-reported height against physically measured height in the same participants:
- A study published in the British Medical Journal found that men overreported their height by an average of 0.78 inches (2.0 cm)
- Dating apps see this inflation routinely. Research on OkCupid data found that men who listed 6 feet as their height skewed heavily toward 5’11” when measured
- The effect is strongest for men who are just below a socially desirable threshold. A man who measures 5’11.5″ is much more likely to round up to 6’0″ than a man who measures 5’9.5″ is to round to 5’10”
Practical Implication: If someone on a dating profile lists their height as 6’0″, their physically measured height is statistically more likely to be between 5’10.5″ and 5’11.5″. The CDC NHANES data used throughout this article is collected through physical measurement, which is why it is the most reliable source for actual male height statistics.
What Influences Male Height?
Height is not randomly assigned. It is the result of an interaction between genetic potential and environmental factors during childhood and adolescence. Understanding what actually drives height helps separate myth from reality.
Genetics (80% of Height)
The largest single determinant of how tall you will grow. Research suggests genetics accounts for roughly 60 to 80 percent of height variation between individuals. Your height potential is largely encoded in your DNA from birth, drawn from both parents and their ancestral lines.
Nutrition During Childhood
Adequate protein, calcium, zinc, and vitamin D during the growth years are critical for reaching genetic height potential. Chronic malnutrition or micronutrient deficiencies during childhood can permanently limit adult height, even if genetics would have supported greater growth.
Hormonal Factors
Growth hormone, secreted by the pituitary gland, drives the bone lengthening that occurs during childhood and puberty. Conditions like growth hormone deficiency or excess (gigantism) can substantially affect final height regardless of genetic potential.
Sleep Quality in Childhood
Growth hormone is predominantly released during deep sleep. Chronic sleep disruption during childhood and adolescence can interfere with the normal secretion pattern and may modestly limit height gains, though this factor is smaller than genetics or nutrition.
Socioeconomic Status
Average height at the population level is closely linked to economic development. Wealthier countries with better food access, healthcare, and reduced disease burden consistently see taller populations. This is why global height averages have risen over the past century alongside economic development.
Age-Related Decline
After peak height in the 30s, men lose approximately 0.4 to 0.6 inches per decade starting around age 40, and up to a full inch or more between ages 60 and 80. This is driven by spinal disc compression, reduced vertebral spacing, and postural changes.
Height and Men's Health: What the Research Shows
Height is not just a demographic measurement. Research has found meaningful associations between height and various health outcomes in men. These are statistical associations, not deterministic rules, and they reflect population-level trends rather than individual predictions.
Health Associations With Taller Stature
- Reduced cardiovascular risk: Some studies show taller men have lower rates of coronary heart disease, possibly due to the larger arterial diameters that tend to accompany greater height
- Lower stroke risk: Research suggests taller stature is associated with a modestly reduced likelihood of stroke
- Reduced Alzheimer’s risk: Some research has found associations between taller height and reduced risk of Alzheimer’s disease, though this relationship is complex and not fully understood
- Higher earnings on average: Multiple economic studies have found that taller men tend to earn more on average, with some estimates suggesting each additional inch of height is associated with roughly 1 to 2% higher annual earnings
Health Associations With Greater Height That Cut the Other Way
- Higher prostate cancer risk: A 2017 study published in the British Journal of Cancer found that men taller than 5’10” were 22% more likely to develop high-grade prostate cancer than men shorter than 5’8″
- Joint stress: Greater height places more mechanical stress on weight-bearing joints, which may contribute to higher rates of certain joint conditions over time
Medical Perspective: Height is one data point among many in assessing health risk. It is useful context for clinicians but should never be used to make assumptions about individual health outcomes. Regular health screenings and lifestyle factors have far more influence on long-term health than any height-related statistical association.
Height in Dating: What the Data Reveals
Male height statistics take on a very different kind of significance in the context of dating. Height is one of the most commonly cited preferences in online dating profiles, and the gap between the average American man’s height and the most common height minimums people set is larger than many people realize.
The national average of 5’9.1″ sits almost a full inch below the height of an even 5’10” man. The most common height minimum stated in dating preferences, 6’0″, is 2.9 inches above the national average. To put this another way: a 6-foot minimum immediately eliminates approximately 85.5% of American men from consideration, before any other preference is applied.
This does not mean height preferences are unreasonable. It means understanding the actual numbers leads to more informed decisions. For related reading, see:

Frequently Asked Questions
What is the average male height in the US?
The average male height in the United States is 5 feet 9.1 inches (approximately 175.3 cm), based on physical measurement data from the CDC’s National Health and Nutrition Examination Survey (NHANES 2015-2018). This is the most authoritative source available because the heights were physically measured by trained health technicians rather than self-reported by participants.
Is 5'9" short for an American man?
No. 5’9″ is exactly the average height for American men according to CDC NHANES data. A man at 5’9″ is taller than approximately 50% of the adult male population and shorter than the other 50%. The perception that 5’9″ is short is partly driven by the fact that men frequently overreport their height by 0.5 to 1 inch, which inflates the perceived average in casual conversation and on dating platforms.
What is considered tall for an American man?
Based on the height distribution of American men, being in the top 25% means being approximately 5’11” or taller. Being in the top 15% means being 6’0″ or taller. Being in the top 5% means being approximately 6’2″ or taller. Statistically, 6 feet is a reasonable definition of tall by American standards, placing a man above roughly 85% of the male population.
Do American men get taller or shorter with age?
Both. Men reach peak height around their 30s, when the average is approximately 5’9.6″. Height then begins a gradual decline starting around age 40 due to spinal disc compression and bone density loss. By the 70s, the average male height drops to approximately 5’8.1″, and men in their 80s and above average around 5’7.1″. This is a normal part of aging and affects virtually all men to some degree.
How does US male average height compare to other countries?
The average American man at 5’9.1″ is above the global average of approximately 5’7″ but shorter than men in most Northern and Western European countries. Dutch men are the world’s tallest at an average of 6’0.4″. Men in the UK and Canada average about 5’10”. American men are slightly shorter than their British and Canadian counterparts and notably shorter than Northern Europeans, placing the US roughly in the middle of the developed-world height range.
What percentage of American men are over 6 feet tall?
Approximately 14.5% of American men are 6 feet or taller, based on CDC NHANES physical measurement data. That means roughly 1 in 7 men clears the 6-foot mark. Only about 3.2% of men are 6’2″ or taller, and fewer than 1.1% reach 6’4″. For the complete breakdown including data by age and ethnicity, see our dedicated article on what percentage of American men are over 6 feet tall.
The Bottom Line
The average male height in the US is 5 feet 9.1 inches (175.3 cm) based on CDC NHANES physically measured data from 2015 to 2018. This is the most reliable figure available because it comes from direct measurement rather than self-reporting, which inflates heights by roughly 0.5 to 1 inch on average.
Height varies meaningfully by age group (peaking in the 30s at 5’9.6″ and declining to 5’7.1″ by age 80+), by ethnicity (ranging from 5’6.9″ for Mexican American men to 5’10.0″ for Non-Hispanic White men), and by global context (placing American men above the world average but below most Northern European countries).
