What Is The Average Height For Women?

The average height for women in the United States is 63.5 inches, or 5 feet 3.5 inches (about 161 cm), according to the most recent CDC/NCHS anthropometric data (CDC, 2025). That figure comes from measurements taken on adult women age 20 and older, not from people estimating their own height on a survey form. It’s a population average, not a target, and it shifts depending on age group, ethnicity, and which years the data was collected.

Key Takeaways

• The average U.S. woman age 20 and older measures 5 ft 3.5 in (63.5 inches, 161.3 cm).
• This figure comes from NHANES measurements taken between August 2021 and August 2023.
• Height drops slightly with age, mostly due to spinal and disc compression rather than actual bone shrinkage.
• Genetics accounts for roughly 80% of height variation between individuals (MedlinePlus Genetics).
• Percentiles tell you more about where you personally fall than the average ever will.

What Is the Average Height for Women in the United States?

The measured average for American women 20 and older is 63.5 inches, equal to 5 feet 3.5 inches, or 161.3 cm (CDC/NCHS, Series 3 No. 46). The data behind that number comes from the National Health and Nutrition Examination Survey (NHANES), a CDC program that pairs in-home interviews with physical exams at mobile centers, which is why these numbers hold up better than self-reported survey data usually does.

That 63.5-inch figure is a mean, meaning it’s calculated by adding up every measured height and dividing by the sample size. It isn’t a “normal” height in any prescriptive sense. Plenty of healthy, perfectly typical women sit several inches above or below it.

One nuance worth knowing upfront: the 63.5-inch mean has stayed essentially flat across the two most recent NHANES cycles, while the men’s average ticked down slightly from 69.0 to 68.9 inches between cycles. Small year-to-year shifts like that are normal statistical noise, not a sign that women are suddenly getting taller.

Average Female Height by Age

Average height for women peaks in their twenties, then declines gradually from there. Women age 20 to 29 average around 64.0 to 64.4 inches, while women 80 and older average about 61.7 inches (CDC/NCHS, Series 3 No. 46). That’s roughly a 2.7-inch gap between the youngest and oldest adult groups measured.

This drop isn’t about bones shrinking the way people sometimes picture it. What’s actually happening is the spinal discs that sit between vertebrae lose fluid and compress over decades, and posture tends to shift slightly with age-related changes in muscle and bone density. The skeleton itself isn’t getting shorter; the spacing between its parts is tightening up.

This age-related pattern is different from what happens during adolescence, when height is still actively changing for a completely different reason: growth plates haven’t closed yet. For readers tracking a teenager’s growth rather than an adult’s gradual height loss, the benchmarks for average height for teenagers follow a separate set of CDC growth charts entirely.

What Height Is Considered Short or Tall for a Woman?

There’s no official medical cutoff for “short” or “tall” in a healthy adult woman. Statisticians instead describe where someone falls using percentiles, which show what portion of the population measures shorter or taller than a given height.

Based on NHANES data, the middle 50% of U.S. women fall between about 61.6 and 65.4 inches. The 5th to 95th percentile range runs wider, from roughly 58.9 to 67.9 inches. Falling outside that range doesn’t mean anything is wrong; it just means you’re in the tails of a bell curve that covers tens of millions of people.

A woman at the 10th percentile isn’t medically short. She’s statistically uncommon, which is a different thing entirely. Clinicians reserve terms like “short stature” for cases well outside this range, usually combined with other signs, not for anyone sitting near the edges of a normal distribution.

What Determines a Woman’s Height?

Genetics accounts for roughly 80% of the variation in height between individuals, according to MedlinePlus Genetics, the National Library of Medicine’s consumer genetics resource (MedlinePlus Genetics). The remaining variation comes from a mix of nutrition, overall health during childhood, and other environmental factors.

Height is polygenic, meaning it’s influenced by thousands of gene variants working together rather than one single “height gene.” That’s part of why predicting a child’s exact adult height from parental height alone is more art than science, even though genetics and height are closely linked at the population level.

Nutrition matters most during two windows: infancy and puberty, when growth plates in the long bones are most active. Chronic illness, inadequate protein or micronutrient intake, and poor sleep during those windows can shave real inches off adult height, even when genetic potential was higher. Once growth plates fuse, usually by the late teens for women, height is essentially locked in regardless of diet or exercise changes afterward.

How Does the Average U.S. Woman Compare With Women Worldwide?

American women average taller than women in many countries but shorter than women in several Northern European nations. Global height datasets compiled by NCD-RisC and published through Our World in Data show substantial country-to-country variation, with Dutch and Latvian women ranking among the tallest in the world and women in parts of South and Southeast Asia averaging noticeably shorter.

Comparing these figures across countries requires some caution. Different nations collect height data differently, some rely on measured exams like NHANES while others use self-reported survey data, and sample years don’t always line up. A country’s average also reflects decades of accumulated nutrition and public health conditions, not a single point-in-time snapshot.

What jumps out comparing these numbers side by side is how much that Dutch figure outpaces the U.S. average, nearly three inches. Diet, healthcare access, and selective genetic patterns across generations all played a role in that gap, and it developed over roughly a century, not overnight.

Has the Average Height of Women Changed Over Time?

Average height for U.S. women rose through most of the 20th century before leveling off. Improvements in childhood nutrition, reduced disease burden, and better prenatal and early-childhood healthcare drove most of that increase, a pattern researchers call a “secular trend” in height.

That upward trend has largely plateaued in the U.S. over the past few decades. Some countries are still seeing increases, generally ones that started from a lower nutritional baseline and have since caught up economically. The U.S. plateau suggests the population has largely reached the height ceiling set by its current genetic and nutritional conditions.

How to Measure Your Height Accurately

Accurate height measurement requires bare feet, a hard floor, and a flat wall, standing with heels, shoulder blades, and the back of the head touching the wall. A flat object like a book or ruler placed level on top of the head, then marked against the wall, gives a far more reliable reading than most bathroom scale attachments or phone apps.

Measure first thing in the morning when possible. Spinal compression from a day of standing and sitting can shave up to half an inch off an evening measurement, which is enough to skew results if you’re tracking change over time rather than just checking a single number.

Final Thoughts

The average height for American women sits at 5 feet 3.5 inches, a figure pulled from measured CDC data rather than guesswork. Where any individual woman falls relative to that number comes down mostly to genetics, with nutrition and health during childhood filling in the rest. If height feels like a concern worth discussing, whether for yourself or a child, a pediatrician or primary care provider can place an actual measurement against growth charts and percentiles far more usefully than a single national average ever could.

FAQ

What is the average height for a woman in the U.S.?
5 feet 3.5 inches, or 63.5 inches, based on CDC measurements of women age 20 and older.

Is 5’4″ tall for a woman?
It’s slightly above average, landing around the 55th to 60th percentile nationally. It’s common, not unusually tall.

At what age do women stop growing taller?
Most women reach their adult height by around 14 to 15, once growth plates fuse, though some continue slightly into their late teens.

Why do women get shorter with age?
Spinal discs lose fluid and compress over decades, and bone density changes can affect posture, not because bones themselves shrink.

Does genetics really determine most of a woman’s height?
Roughly 80% of height variation between individuals traces back to inherited genetics, with nutrition and health filling in the remaining share.

How much shorter are women than men on average in the U.S.?
About 5.4 inches, based on the latest CDC figures: 63.5 inches for women versus 68.9 inches for men.
