The average American woman stands 5 feet 3.5 inches tall (63.5 inches, or about 161 cm). That figure comes from the CDC’s most recent national survey, which directly measured adults age 20 and older between 2021 and 2023. If you’re close to that number, you’re right in the middle of the pack.
How Height Varies by Ethnicity
The national average blends together groups with noticeably different typical heights. Non-Hispanic Black women tend to be the tallest demographic at around 5 feet 4 inches. Non-Hispanic white women average just over 5 feet 3 inches, which sits close to the national figure. Hispanic women average about 5 feet 2 inches, and non-Hispanic Asian women average roughly 5 feet 1 inch.
These differences reflect a mix of genetics, nutrition patterns, and other environmental factors across populations. None of these averages represent an ideal. They’re simply snapshots of where the center point falls for each group.
Height Changes With Age
If you’ve noticed you’re slightly shorter than you used to be, that’s normal. People typically lose about half an inch of height every decade after age 40. That means a woman who measured 5 feet 5 inches at 30 could be closer to 5 feet 3 inches by her 70s.
This shrinkage happens for a few reasons. The discs between your vertebrae lose water content and compress over time. Bone density decreases, especially after menopause, which can cause slight compression fractures in the spine. Postural changes from weakening core and back muscles also contribute. The result is that younger women in their 20s and 30s tend to pull the national average up slightly, while women over 60 bring it down.
Where American Women Rank Globally
At 5 feet 3.5 inches, American women fall in the middle of the global range. Women in the Netherlands, Denmark, and other Northern European countries tend to be the tallest in the world, averaging around 5 feet 6 inches. On the other end, women in parts of Southeast Asia and Central America average closer to 5 feet or below. Within the developed world, American women are roughly average, similar to women in the UK and France.
What Determines Your Height
Genetics account for roughly 60 to 80 percent of your final adult height. The rest comes down to environmental factors, primarily nutrition during childhood and adolescence. Adequate protein, calcium, vitamin D, and overall calorie intake during growth years all play a role. Chronic illness or severe stress during childhood can also limit growth potential.
This is why average heights have increased over the past century. American women today are about 2 inches taller than women in the early 1900s, not because of genetic changes but because of better nutrition, fewer childhood infections, and improved healthcare. That trend has largely plateaued in the U.S. over the last few decades, suggesting most American women are now reaching close to their full genetic height potential.
What “Average” Actually Means in Practice
The 5-foot-3.5-inch figure is a mean, which means roughly half of American women are shorter and half are taller. Most women cluster within a few inches of this number. About 68 percent of women fall between approximately 5 feet 1 inch and 5 feet 6 inches. Being outside that range is perfectly normal too, just less common.
Height matters practically for things like clothing sizes, ergonomic furniture, car seat adjustments, and medical dosing calculations. If you’re shopping for petite or tall sizing, most clothing brands define “petite” as 5 feet 4 inches and under, and “tall” as 5 feet 8 inches and above. Knowing where you stand relative to the average can help you navigate those choices more easily.
