When you step on the scale, that little digital number feels like a final grade on your health. It’s stressful. Honestly, it’s even more confusing when you're 5'4" because you’re essentially the "average" height for a woman in the United States, yet the advice you find online is all over the map. You’ve probably seen charts telling you one thing and influencers telling you another.
What is the average weight for a 5 4 female?
If we’re looking strictly at the data from the Centers for Disease Control and Prevention (CDC), the "average" weight for an American woman of this height is approximately 170.8 pounds.
That number surprises a lot of people. Why? Because while it's the statistical average, it doesn't align with what medical organizations define as the "healthy" or "ideal" range. There is a massive gap between what we actually weigh and what the formulas say we should weigh.
The Massive Gap Between Average and Healthy
Let's get into the weeds of the numbers. According to the National Health and Nutrition Examination Survey (NHANES), the average weight for women in the U.S. has been climbing for decades. A woman who is 5'4" and weighs 170.8 pounds has a Body Mass Index (BMI) of roughly 29.3.
In the eyes of the medical establishment—like the World Health Organization (WHO)—this falls into the "overweight" category, just a hair's breadth away from "obese" (which starts at a BMI of 30).

But wait.
Does "average" mean "bad"? Not necessarily. It just reflects the current reality of our lifestyle, diet, and environment. If you want to know what the medical "ideal" is, the CDC suggests a healthy BMI range of 18.5 to 24.9.
For someone who is 5'4", that translates to a weight range of 108 to 145 pounds.
That’s a huge 37-pound window! It’s also significantly lower than the national average. This is where most people start to feel the "scale anxiety," but the "ideal" weight is a lot more nuanced than a single number on a chart.
Why BMI Is Kinda Flawed (But Still Used)
We have to talk about BMI. Doctors love it because it’s easy. It’s just math: weight divided by height squared. But BMI doesn’t know the difference between five pounds of jiggling fat and five pounds of dense, metabolic muscle.
Imagine two women. Both are 5'4". Both weigh 160 pounds.
- One is a dedicated CrossFit athlete with a low body fat percentage and high muscle mass.
- The other is sedentary and carries most of her weight around her midsection.
The BMI calculator labels both as "overweight," but their health risks are worlds apart. Muscle is much denser than fat. If you’re hitting the gym and the scale isn't moving—or even going up—you might actually be getting healthier despite what the "average weight for a 5 4 female" charts say.

Formulas That Try to Predict Your "Ideal"
Before BMI became the king of the clinic, researchers used various formulas to find the "Ideal Body Weight" (IBW). You might see these used in clinical settings to determine medication dosages.
- The Hamwi Formula (1964): This one is an old-school favorite. It starts at 100 lbs for the first 5 feet and adds 5 lbs for every inch after that. For a 5'4" woman, that’s $100 + (4 \times 5) = 120$ pounds.
- The Devine Formula (1974): Often used in hospitals, this one suggests roughly 122 pounds (55.5 kg) for a 5'4" woman.
- The Robinson Formula (1983): A bit more modern, it lands at about 127 pounds.
Notice a trend? These formulas all suggest weights in the 120s. That’s nearly 50 pounds lower than the actual American average. It’s no wonder we feel like we’re constantly failing a test we didn't sign up for.
Factors That Actually Change Your Number
Your "perfect" weight isn't a fixed point. It’s a moving target influenced by things you can't control—and a few you can.
Frame Size and Bone Density
Some people are literally "big-boned." It's not a myth. A small-framed woman and a large-framed woman, both 5'4", will have different baseline weights. You can check this by wrapping your thumb and middle finger around your wrist. If they overlap, you likely have a small frame. If they don't touch, you're likely large-framed.
Age and Hormones
Metabolism slows down. It’s annoying, but it’s true. After menopause, the drop in estrogen often leads to a shift in weight distribution. Research in the Journal of Clinical Endocrinology & Metabolism shows that postmenopausal women often see an increase in visceral fat (the kind around your organs) even if the number on the scale stays the same.
The Role of Muscle
I’ll say it again: muscle is heavy. If you have a high Lean Body Mass (LBM), you will weigh more. This is actually a good thing! Muscle burns more calories at rest and protects your bones as you age.
Beyond the Scale: Better Ways to Measure Health
If the average weight for a 5 4 female is a confusing metric, what should you actually look at?
1. Waist Circumference
According to the National Heart, Lung, and Blood Institute, a waist measurement over 35 inches for women is linked to a higher risk of heart disease and Type 2 diabetes. This is often more telling than total body weight because it tracks "active" fat that messes with your hormones.

2. Waist-to-Height Ratio
A simple rule of thumb? Keep your waist circumference to less than half your height. For a 5'4" (64 inches) woman, your waist should ideally be under 32 inches.
3. Energy and Blood Work
How do you feel? Can you climb a flight of stairs without gasping? Are your blood pressure, cholesterol, and A1C levels in the healthy range? A "textbook weight" person with high blood sugar is often in more danger than a slightly "overweight" person with perfect metabolic markers.
Actionable Steps for Finding Your Healthy Range
Stop chasing the "average." Instead, focus on these specific metrics to find the weight where your body actually functions best.
- Get a DEXA Scan or Bioimpedance Scale: If you’re serious about fitness, stop looking at total weight and start looking at body fat percentage. A healthy range for women is typically 21% to 32%.
- Track Your Waist, Not Just Your Weight: Use a soft measuring tape once a month. Measure at the narrowest part of your torso (usually just above the belly button).
- Prioritize Strength Training: Aim for at least two days a week. Building muscle will make you "heavier" on the scale but leaner and healthier in reality.
- Focus on Nutrient Density: Instead of just cutting calories to hit a magic number, focus on getting 25-30 grams of protein per meal to maintain the muscle you have.
The "average weight for a 5 4 female" is just a data point in a government spreadsheet. It isn't a command. Your best weight is the one that allows you to live your life with energy, protects you from chronic disease, and is sustainable without extreme dieting.
Compare your current waist circumference to the "half your height" rule to see where you stand metabolically.
Check your latest blood panel for "HDL" cholesterol and "Triglycerides"—the ratio between these two is often a better predictor of heart health than your BMI.
Set a non-scale goal, like performing 10 full push-ups or walking 10,000 steps for 30 days straight, to shift your focus from gravity to capability.
