What Is the Average Height for Women?

The average height for women in the U.S. comes up a lot — in doctor’s offices, on clothing size charts, in those moments when you’re wondering if your teenager’s growth is on track. The number itself is straightforward. What’s behind it is a bit more interesting.

The average height for adult women in the United States is 63.5 inches (5 feet 3.5 inches). This figure comes from the CDC’s National Center for Health Statistics, based on NHANES survey data collected August 2021–August 2023 from a nationally representative sample of adults aged 20 and older. (CDC NCHS, 2025)

Key Takeaways

• The average American adult woman stands 63.5 inches (5’3.5″), according to the most recent CDC data.
• Height is roughly 80% genetic — environment fills in the rest.
• U.S. women rank in the middle of the global distribution; Dutch women average nearly 3 inches taller.
• Height typically peaks in the late teens and slowly declines after age 40, mostly due to spinal compression.
• Population averages describe groups — they say nothing meaningful about whether any individual is healthy.

How the CDC Measures This (and Why It Matters)

The figure isn’t from a survey asking people how tall they are. That would be useless — people consistently overestimate their height by about half an inch. (Fryar et al., 2025)

NHANES uses trained examiners who measure participants in a mobile examination center, without shoes, standing against a stadiometer with their heels, back, and head properly positioned. That methodological rigor is what makes the CDC number the most reliable reference in the country — and why it’s worth citing instead of the vague “around 5’4″” figures that circulate online.

The current data period (August 2021–August 2023) covers women 20 and older across all racial and ethnic groups, giving the 63.5-inch average its statistical weight.

How American Women Compare to the Rest of the World

The U.S. average sits solidly in the middle of the global distribution — not at the top, not near the bottom.

Dutch women average around 5’6.5″ (170 cm), making the Netherlands home to the world’s tallest female population. Scandinavian countries cluster nearby. At the other end, women in Guatemala average closer to 4’11”. (NCD-RisC, 2016)

A century ago, American women were among the tallest in the world. That’s no longer true. European heights accelerated through the mid-20th century while U.S. gains slowed — a divergence researchers attribute to differences in healthcare access, inequality, and diet quality. (Komlos & Lauderdale, 2007)

That’s the less-flattering data point most “average height” articles quietly skip.

What Actually Determines How Tall a Woman Gets

Genetics: The Dominant Factor

Genetics account for roughly 80% of final height variation in well-nourished populations. (Silventoinen, 2003) A landmark 2022 genome-wide study identified over 12,000 genetic variants associated with height across 5.4 million participants. (Yengo et al., 2022)

What this means practically: the ceiling is mostly set before birth. The other 20% is where lifestyle factors do their work — and that remaining margin is still large enough to matter.

Nutrition During Childhood and Adolescence

Nutrition is the most important external factor for linear growth. Protein, calcium, and vitamin D during the growth years are where the evidence is strongest. (Perkins et al., 2016)

One specific finding worth knowing: girls who consumed more than three servings of dairy per day during adolescence showed meaningfully greater height gains than peers who consumed less. (Wiley, 2005) The effect isn’t enormous — this isn’t a cheat code — but it’s real and consistent.

Sleep and Growth Hormone

Most of the body’s growth hormone is released during slow-wave sleep — not in a trickle throughout the day, but in concentrated pulses during the first few hours after falling asleep. (Shaw et al., 2023) Disrupting that sleep disrupts those pulses. For growing girls, the implication is practical: hitting 9 science-backed tips to grow taller consistently requires treating sleep as a non-negotiable, not a nice-to-have.

Socioeconomic Factors

Income inequality has a measurable negative association with average height — larger, in fact, than the effect of absolute income. (Bogin et al., 2017) Healthcare access, food security, and chronic stress during childhood all leave marks on final adult stature.

This is why population averages can shift over generations even when the gene pool stays constant.

Average Height for Women by Age

Height isn’t fixed for life. It just mostly is.

Women typically reach their full height in their mid-to-late teens, after growth plates close — usually between ages 13 and 15, though it varies. (Fryar et al., 2025)

From the 20s through the late 30s, height is stable. After 40, a gradual loss begins — typically about 0.4 inches per decade, primarily from spinal compression and reduced disc height. Osteoporosis accelerates this, particularly after menopause, when bone density loss speeds up.

By age 70, many women have lost 1–2 inches from their peak. This isn’t failure of anything — it’s just aging biology.

Average Height for Women by Ethnicity in the United States

The 63.5-inch national average is a blend across a diverse population. The breakdown by race and ethnicity, from NHANES data, shows meaningful variation. (Fryar et al., 2025)

Non-Hispanic White and Non-Hispanic Black women tend to average slightly above the national figure. Hispanic and Asian American women tend to average somewhat below it — reflecting both genetic background and the influence of nutrition and healthcare access across generations.

These are population patterns, not destiny. Socioeconomic factors, immigration generation, and early childhood nutrition all layer on top of genetic tendencies, making individual prediction essentially impossible from group averages alone.

Is the Average Height for Women Changing Over Time?

For most of the 20th century, Americans got taller — driven by improved nutrition, reduced childhood disease, and broader access to healthcare. (Ogden et al., 2004)

That trend has reversed. Research published in 2025 found that U.S. heights have been declining since birth cohorts of the early 1980s, with Hispanic men showing the steepest drop — nearly 2 cm — and White women the most modest decline of about 0.68 cm. (Bogin & Komlos, 2025)

The proposed causes aren’t mysterious: rising income inequality, worsening diet quality in lower-income populations, and gaps in prenatal and pediatric care. The same forces that stalled life expectancy gains appear to be showing up in height data. That parallel is not a coincidence.

Why Average Height Data Actually Gets Used

The practical applications of height averages aren’t just academic. They show up in:

Clothing and apparel sizing. U.S. women’s “standard” sizing is calibrated around the national average — which is why petite and tall lines exist, and why fit varies so dramatically between brands that use slightly different reference populations.

Ergonomics and furniture. Office desk and chair standards, kitchen counter heights, vehicle seat positions — all are derived from population height distributions. A country with a taller average female population would design these differently.

Medical assessments. Height-for-age percentiles are used clinically to flag growth concerns in children, and height relative to historical personal measurements is one marker for bone loss in older adults. BMI calculations depend on accurate height measurement.

None of this requires individual women to worry about where they land. But it explains why researchers keep measuring.

Final Takeaway

The average height for women in the United States is 63.5 inches — 5’3.5″ — measured from a nationally representative sample of adults by the CDC. Genetics set roughly 80% of that number before a girl is born. Nutrition, sleep, and childhood health conditions shape the rest.

The more useful frame isn’t “am I average?” — it’s understanding that height data describes populations, tracks public health trends, and informs product design. Individual variation is normal. The averages exist to describe the group, not to evaluate the person.
