The average weight for an adult woman in the United States is approximately 170 pounds, based on national survey data collected by the CDC. The average height is about 5 feet 3.5 inches. These numbers reflect statistical averages across all adult age groups, not necessarily what’s healthy for any individual woman.
That distinction matters. “Average” and “healthy” are two different things, and understanding the gap between them can help you figure out where your own weight fits in the bigger picture.
Average Weight by Age
Weight tends to increase through midlife and then gradually decline in older age. Women in their 20s tend to weigh less than women in their 40s and 50s, partly because of natural shifts in metabolism, muscle mass, and hormonal changes. After about age 60, average weight typically drops as lean body mass decreases.
As a rough guide from national survey data, average weights for U.S. women by age group look something like this:
- 20 to 39: around 167 pounds
- 40 to 59: around 176 pounds
- 60 and older: around 166 pounds
These figures shift slightly with each data cycle. The CDC’s National Health and Nutrition Examination Survey (NHANES), which physically measures participants rather than relying on self-reported numbers, published its most recent cycle covering August 2021 through August 2023.
Why “Average” Doesn’t Mean “Healthy”
The average American woman’s weight puts her BMI at roughly 29.6, which falls in the overweight category and sits just below the threshold for obesity. That’s not a judgment on any individual. It reflects a population-wide pattern that has shifted significantly over time.
The World Health Organization defines a normal weight as a BMI between 18.5 and 24.9. For a woman who is 5 feet 4 inches tall, that translates to roughly 108 to 145 pounds. A BMI of 25 or higher is classified as overweight, and 30 or higher as obese. Below 18.5 is underweight, and below 17 is classified as thinness.
BMI is a blunt tool. It doesn’t account for muscle mass, bone density, or where you carry your fat. A muscular woman and a sedentary woman of the same height can have identical BMIs with very different health profiles. Still, at a population level, it’s useful for spotting broad trends.
Waist Circumference as a Better Clue
Where your body stores fat often matters more than total weight. Fat around the midsection (visceral fat) is more strongly linked to heart disease, type 2 diabetes, and metabolic problems than fat stored in the hips or thighs.
The average waist circumference for American women has risen to about 38.6 inches, up from 36.3 inches in earlier measurements. A waist measurement above 35 inches is generally considered a risk marker for women, meaning the current average already exceeds that threshold. If you’re curious about your own risk profile, a tape measure around your waist at the navel can tell you something a scale cannot.
How Race and Ethnicity Factor In
Average weight varies across racial and ethnic groups in the U.S., driven by a mix of genetics, socioeconomic factors, food access, and cultural differences. Obesity rates among women ages 18 to 44 illustrate this clearly: 43.8% of Black women fall into the obese category, compared with 31.5% of White women and 12.3% of Asian women. That’s a 3.6-fold difference between the highest and lowest groups.
These numbers don’t mean any individual should expect a certain weight based on their background. They do mean that population averages can be misleading if you’re comparing yourself to a single national figure that blends very different groups together.
Weight Has Increased Significantly Over Decades
The average American woman today weighs considerably more than her counterpart in the early 1960s. CDC data tracking weight from 1960 to 2002 found that mean weight among adults increased by more than 24 pounds over that period, and the trend has continued since. For context, the average woman in the early 1960s weighed closer to 140 pounds.
This shift isn’t about individual willpower. Portion sizes, food processing, sedentary work environments, stress levels, and sleep patterns have all changed dramatically. The average American diet contains more ultra-processed food and added sugar than it did 60 years ago, and daily physical activity has dropped as jobs have moved indoors and screen time has expanded. The weight increase is a population-level response to a fundamentally different environment.
What a “Healthy Weight” Actually Looks Like
Rather than fixating on one number, a more useful approach is to look at a cluster of indicators. Your weight relative to your height (BMI), your waist circumference, your blood pressure, blood sugar levels, and cholesterol together paint a much clearer picture of health than any single measurement.
A woman can weigh more than the “normal” BMI range and still have excellent metabolic health. She can also weigh well within range and have early signs of insulin resistance or cardiovascular risk. Weight is one data point, not a verdict.
If you’re trying to figure out a reasonable target weight for your body, the BMI range of 18.5 to 24.9 gives a starting framework. For common heights, that works out to roughly:
- 5’0″: 95 to 127 pounds
- 5’3″: 107 to 141 pounds
- 5’5″: 114 to 150 pounds
- 5’8″: 125 to 163 pounds
These ranges are wide for a reason. Frame size, muscle mass, and body composition all create legitimate variation within them. The number that matters most is the one where your body functions well, your energy is steady, and your key health markers look good.
