When you're trying to determine a healthy weight for yourself, it may be helpful to know what the average woman weighs. However, just because a figure is an average, does not necessarily mean that it's a good target weight for you. In fact, adults in the United States are trending toward being overweight and obese, so it would be better to use other factors, such as body mass index (BMI), to give you a more accurate goal.

The Average Weight for Women

According to the National Center for Health Statistics, the average weight for an adult woman (20 years old and older) in the United States is 168.5 pounds. This statistic is from the National Health and Nutrition Examination Survey (NHANES) conducted from 2011-2014. It is up from 162.9 pounds noted in the previous survey (2007–2010).

The study also says that the average height for adult women is about 64 inches, or 5 foot 4 inches. The average waist circumference is 38 inches and the average body mass index (BMI) is 29.2, which is considered overweight.

The BMI is a better gauge of most women's healthy weight range, though it's not perfect. It takes into account your height as well as your weight and is measured on a scale that includes underweight, normal weight, and overweight categories. A simple BMI calculator will help you find out where you're at and can be used periodically to track any weight loss goals you may have.

Average Weight Worldwide

When both men and women are factored into the equation, the adult population of North America has a higher average body mass than the rest of the world. One study notes that 73.9 percent of people in North America are considered overweight, compared to 34.7 percent of the world population.

Europe156 pounds

Latin America/Caribbean149 pounds

Oceania163 pounds
World136 pounds

Average Weight Over Time

How has the average weight of an adult woman changed over the years? Measurements of BMI, weight, height, and even head circumference have been measured since the 1960s. Not surprisingly, women in the United States have been getting bigger, both taller and weighing more.

In the early 1960s, a report stated that "American men range in average weight from 146 pounds at 62 inches in height to 190 pounds at 73 inches; while for American women this average progresses from 129 pounds at 58 inches to 157 pounds at 67 inches."

Average Weight for Girls

The average weight for a girl depends on her age. According to the NHANES survey, the average weight for girls in the U.S. is:

AgeAverage Weight
1 year24.6 pounds
2 years29.3 pounds
3 years34.5 pounds
4 years40.3 pounds
5 years45.0 pounds
6 years52.4 pounds
7 years58.7 pounds
8 years69.9 pounds
9 years82.7 pounds
10 years90.9 pounds
11 years104.5 pounds
12 years122.9 pounds
13 years122.4 pounds
14 years131.4 pounds
15 years141.7 pounds
16 years143.3 pounds
17 years148.5 pounds
18 years148.2 pounds
19 years150.9 pounds

Just as with adults, the average does not necessarily correlate with a healthy weight for girls. According to the U.S. Centers for Disease Control and Prevention (CDC), one in five children is obese, which is evident in these national averages.

A more accurate gauge for your child's weight and height is to use a kids growth chart. Comparing a child to the 50th percentile will give you a better idea of how her growth compares to the expected growth rate for girls her age.

A Word From Verywell

The average weight for women in any particular country can tell a lot about trends, but it should not be used as a gauge for your own weight.

Individual factors will play a role in your personal ideal target weight and it's best to consult your physician, trainer, or nutritionist if you have any questions.
