Average Measurements Of American Women | Sizes And Data

These figures come from the National Health and Nutrition Examination Survey (NHANES) collected during August 2021–August 2023 and published by the National Center for Health Statistics. The tables in that report list means for height, weight, body mass index (BMI), waist size, and hip size for U.S. women age 20 and older.

Average Measurements Of American Women: Recent Data

Before you scroll, here’s a compact view of the core numbers. The table shows means for adult women (20+) across the country, based on measured—not self-reported—data.

Metric	U.S. Women (20+)	Source
Height	63.5 in (161.3 cm)	CDC NHANES 2021–2023 tables.
Weight	171.8 lb (77.9 kg)	CDC NHANES 2021–2023 tables.
BMI	30.0	CDC NHANES 2021–2023 tables.
Waist Circumference	97.9 cm (38.5 in)	CDC NHANES 2021–2023 tables.
Hip Circumference	109.8 cm (43.2 in)	CDC NHANES 2021–2023 tables.

What These Averages Mean For Everyday Sizing

NHANES data are measured by trained staff in mobile exam centers. That matters, because self-reports tend to understate weight and waist size. The numbers here reflect a national sample of non-institutionalized adults, weighted to represent the U.S. population.

Average height is about five foot three and a half. Weight averages around 172 pounds. A mean BMI of 30.0 sits at the border of the obesity category by standard cutoffs. Waist size averages near 38.5 inches, while hips average about 43 inches. Together, those measurements help with clothing fit, seat and strap design, workstation setup, and medical risk screening.

How NHANES Measures Height, Weight, And Circumferences

Height is taken with a stadiometer while standing straight, no shoes. Weight is recorded on a calibrated scale. Waist is measured just above the hip bones after a normal exhale; hip is measured at the widest point of the buttocks. These details ensure consistency across sites and years.

Why The Waist Number Gets Extra Attention

Waist size tracks abdominal fat, which ties to risk for heart disease and type 2 diabetes. U.S. clinical guidance flags a waist over 35 inches in women as a higher-risk marker. You can see the method and cutoff on the NHLBI healthy-weight page.

The average waist from the latest NHANES cycle sits above that 35-inch line, which is why clinicians often pair BMI with waist size during routine visits.

Age Bands: How Averages Shift Through Adulthood

The NHANES tables break means down by 10-year age groups. Height drifts down slightly after midlife, while weight, BMI, waist, and hip tend to rise into midlife and then level off or dip in later years. Here are a few patterns worth knowing, drawn from the 2021–2023 release:

Height Across Age

Women 20–29 average about 64.0 inches, while those 60–69 average about 63.2 inches and 80+ about 61.7 inches. The change reflects natural spinal and posture shifts over time.

Weight And BMI Across Age

Weight rises from the late twenties into the 50s, with mean values in the mid- to high-170s, then eases a bit later in life. BMI follows the same arc, with means near 30 in most age bands.

Waist And Hip Across Age

Waist and hip means both climb from the 20s into the 50s. For waist, the mean reaches the low 100s in centimeters during midlife, then flattens or falls slightly. Hip means for women in their 40s and 50s are around 111 cm.

How To Check Your Own Measurements At Home

Height

Stand with heels and back against a wall, no shoes. Use a flat object on your head and make a light mark. Measure from floor to mark with a tape or yardstick.

Weight

Weigh at the same time of day, with light clothing, after using the restroom. Place the scale on a hard, flat surface for steady readings.

Waist

Find the top of your hip bones. Wrap the tape level around your middle, just above the bones, not too tight, and read after a normal exhale. The NHLBI page shows the exact spot. Waist measuring steps.

Hips

Wrap the tape around the fullest part of the buttocks, keeping the tape level all the way around.

Comparisons With Earlier U.S. Cycles

Earlier cycles (2015–2018) reported mean height near 63.6 inches and mean weight around 170.8 pounds for adult women. The current release shows a similar height and a small uptick in mean weight to 171.8 pounds. That continuity reflects a long pattern seen in NCHS briefs.

The latest report is also the first since the early 1990s to bring back hip measurements in a national release, which helps researchers model body shape and risk with more nuance.

Understanding BMI Alongside Waist Size

BMI is weight (kg) divided by height (m) squared. The mean in the current tables is 30.0 for women 20+, which sits at the obesity threshold. BMI is a quick screen, not a diagnosis. Waist size adds context by reflecting fat carried in the abdomen. Clinical guidance uses both.

Clothing Fit: Using The Numbers Without Guesswork

Size charts vary by brand. The safest route is to measure yourself, then match your tape values to each brand’s chart. If you’re between sizes, fabric stretch and rise can decide the better choice. For bottoms, a measured waist and hip will predict fit better than height or weight alone.

Denim Fit Tips

Rigid denim often needs a waist that matches the tape measure; stretch denim can run closer to one size down. In mid-rise styles, the waistband sits lower than the NHANES waist site, so compare your tape value at the band’s height.

Tops And Dresses

Bust, waist, and hip maps guide most dress charts. If a brand lists only bust and waist, use the larger of your two for a clean drape, then tailor if needed.

Home Office And Ergonomics

Height and limb lengths affect desk, chair, and monitor settings. A seat height that keeps knees near hip level suits many adults. If your torso is shorter or longer than average, adjust armrests and monitor height to keep shoulders down and eyes level with the upper third of the screen.

Health Screening: When To Talk With A Clinician

If your waist measures above 35 inches, many clinics will screen for blood pressure, glucose, and lipids, even when BMI is only slightly elevated. That’s because central fat carries added risk; the NHLBI page lays out the threshold and measuring steps.

If your BMI and waist both sit above typical cutoffs, small steady changes—more walking time, more fiber, steady sleep—can improve numbers. For anyone with a personal or family history of heart disease or diabetes, a tailored plan with a licensed clinician is the right move.

Where The Numbers Come From And How To Read Them

NHANES samples the non-institutionalized U.S. population. Teams visit counties in rolling cycles, interview people, and run physical exams in mobile centers. Each person represents others like them through a sampling weight, which is how the mean values become nationally representative.

During 2019–2020, data collection was disrupted, so the pre-pandemic file combines 2017–2018 with partial 2019–March 2020. The 2021–2023 release is a fresh, post-pandemic look with full tables for adults and children, including BMI and waist and the reintroduced hip data.

Average Measurements Of American Women In Context

The phrase average measurements of american women can help with sizing, product design, and health planning. Just remember that averages hide wide ranges. NHANES tables also publish percentiles—from the 5th to the 95th—so designers and clinicians can build for many body shapes, not just one middle value.

Population means also shift across age, ancestry groups, and regions. The national mean is a good yardstick for headlines and high-level planning. For a precise fit or risk check, measure yourself and use clinical cutoffs or brand charts rather than a single national number.

Quick Reference: Cutoffs Many Clinics Use

Measure	Common Cutoff	What It Means
BMI	25.0–29.9 (overweight), 30.0+ (obesity)	Screen for weight-related risk; not a diagnosis.
Waist	Women: >35 in (88.9 cm)	Higher risk marker for heart disease and diabetes.
Height	None	Used with weight for BMI; affects ergonomics and fit.

Frequently Asked Questions

How Current Are These Averages?

They come from NHANES measurements collected August 2021–August 2023 and published in 2025. That makes them the most recent national means for adult women available from NCHS.

Do Clothing Sizes Match These Numbers?

Not reliably. Brands use different blocks and ease. Measure your waist and hips with a tape, then map those values to each brand’s chart. For jeans, check rise; a low or mid rise sits below the clinical waist site and can change the number.

Is Waist More Useful Than BMI?

They answer different questions. BMI screens body mass relative to height, while waist reflects central fat. Many clinics use both: BMI for a quick screen and waist for added risk context.

Why Did Hip Measurements Return To The Report?

Hip data help model body shape, clothing fit, and risk markers such as waist-to-hip ratio. The 2021–2023 report is the first since NHANES III to include hips again, so designers and researchers can build around current shapes.

Where Can I Read The Full Tables?

The complete PDF from NCHS lists means and percentiles for height, weight, BMI, waist, hip, and more, by age bands for women and men. You can view it on the CDC site.

Wrapping It Up – Average Measurements Of American Women

The latest national means point to a woman who stands about 63.5 inches tall, weighs around 172 pounds, carries a BMI near 30, and a waist about 38.5 inches, with hips near 43 inches. Those values help with sizing, workplace setup, and quick health screens. Use them as a reference, not a target. The smartest move is to measure your own height, waist, and hips, then match fit to the brand in front of you and talk with a licensed clinician when you want a tailored plan.
