So, you’re standing in the doctor's office. You look at that laminated chart on the wall, the one that’s been there since 1994, and it tells you that because you’re sixty-two inches tall, you need to hit a very specific, very narrow number. It feels personal. It feels like a grade on a report card. But honestly, trying to figure out what should a 5 2 woman weight is a lot more complicated than just glancing at a grid of squares.
Five-foot-two is a unique height. You’re "petite" in the fashion world, but in the medical world, every pound shows up differently on a shorter frame than it does on someone who is 5'9". A five-pound fluctuation on a tall woman is invisible; on you, it’s the difference between your favorite jeans zipping up comfortably or feeling like a medieval torture device.
The BMI Myth and Why It Fails Shorter Women
Most people start with the Body Mass Index. It’s the old standby. For a woman who is 5'2", the "normal" BMI range usually falls between 101 and 136 pounds. That is a massive thirty-five-pound gap. Think about that. A 105-pound woman and a 135-pound woman are both "healthy" according to the math, even though they look and likely feel completely different.
The math is simple: weight in kilograms divided by height in meters squared. But there’s a glitch. The formula was actually created by a Belgian mathematician named Lambert Adolphe Jacques Quetelet in the mid-1800s. He wasn't even a doctor. He was a statistician looking for the "average man." He didn't account for bone density. He didn't care about muscle mass. He definitely wasn't thinking about the hormonal profile of a modern woman.
If you have a "large frame"—meaning your elbows and wrists are naturally wider—you might naturally sit at the higher end of that range and be perfectly healthy. If you’re a distance runner with very little muscle, you might be at the bottom. Nick Trefethen, a professor of numerical analysis at Oxford University, has actually argued that the standard BMI formula is flawed for shorter people. He suggests that because the formula divides weight by height squared, it makes shorter people think they are thinner than they are, and taller people think they are fatter. He proposed a "New BMI" formula that adjusts the math to be more fair to those of us under 5'5".
Muscle vs. Fat: The Density Debate
Muscle is dense. It’s heavy. It’s also metabolically active, which is a fancy way of saying it burns calories while you're just sitting there watching Netflix.
Imagine two women. Both are 5'2". Both weigh 140 pounds.
Woman A spends her time lifting weights, eats a high-protein diet, and has a low body fat percentage. She probably wears a size 4 or 6.
Woman B doesn't exercise and has a much higher body fat percentage. She might wear a size 10 or 12.

The scale says they are identical. The medical chart says they are both slightly "overweight" by BMI standards. But their health risks are worlds apart. This is why focusing solely on what should a 5 2 woman weight can be a trap.
Waist-to-Hip Ratio: A Better Metric?
If the scale is a liar, what should you look at? Many doctors, including those at the Mayo Clinic, are moving toward the waist-to-hip ratio (WHR). This measures where you carry your weight.
For women, carrying weight in the midsection (the "apple" shape) is linked to much higher risks of heart disease and type 2 diabetes compared to carrying weight in the hips and thighs (the "pear" shape). To find your ratio, measure the narrowest part of your waist and the widest part of your hips. Divide the waist measurement by the hip measurement.
- 0.80 or lower is considered low health risk.
- 0.81 to 0.85 is moderate risk.
- 0.86 or higher is high risk.
For a 5'2" woman, this ratio often tells a much truer story than the scale ever could. You could weigh 145 pounds—technically overweight—but if your waist is 27 inches and your hips are 40 inches, your health profile is likely fantastic.
The Role of Age and Menopause
Let's talk about the elephant in the room: aging. Your "ideal" weight at 22 is almost certainly not your ideal weight at 52.
As women age, especially as they hit perimenopause and menopause, estrogen levels drop. This leads to a natural redistribution of fat. It moves from the hips to the belly. Sarcopenia—the natural loss of muscle mass—also kicks in. If you aren't actively strength training, you're losing muscle and replacing it with fat, even if the number on the scale stays exactly the same.

A study published in the Journal of the American Geriatrics Society suggested that for older adults, being slightly "overweight" by BMI standards might actually be protective. It provides a reserve in case of serious illness and can help prevent osteoporosis. So, if you’re 5'2" and 65 years old, weighing 140 pounds might actually be "healthier" than weighing 110.
Frame Size: The Wrist Test
You've probably heard someone say they are "big-boned." People used to laugh at that, but it's a real physiological thing. Your skeletal structure determines how much weight your body can comfortably carry.
There’s a quick way to check this. Wrap your thumb and middle finger around your opposite wrist.
- If they overlap, you have a small frame.
- If they just touch, you have a medium frame.
- If they don't meet, you have a large frame.
A 5'2" woman with a large frame will naturally and healthily weigh 10% to 15% more than a 5'2" woman with a small frame. If the small-framed woman tries to reach 135 pounds, she might feel sluggish. If the large-framed woman tries to hit 110, she might lose her period or feel constantly exhausted.
Real-World Examples
Let's look at some recognizable figures who are roughly 5'2" to see how differently this weight can manifest.
- Salma Hayek is roughly 5'2". She is famous for her curves and has often spoken about embracing a body that isn't stick-thin.
- Reese Witherspoon is also around 5'2" but has a much more "petite" or "fine" bone structure.
- Nicki Minaj is approximately 5'2" and carries significant muscle and curve.
If all three of these women were forced to weigh exactly 115 pounds, some would look healthy, while others would look gaunt and lose their strength. Your genetics dictate your "set point"—the weight range where your body naturally wants to stay to keep your brain and organs functioning optimally.

The Mental Toll of the Number
We need to address the "goal weight" obsession. Many women pick a number based on what they weighed in high school or what a celebrity weighs. This is a recipe for misery.
When you ask what should a 5 2 woman weight, you’re often actually asking: "How can I feel good in my skin?"
Weight is a data point. It isn't a definition. If you’re eating whole foods, moving your body in a way you enjoy, sleeping well, and your blood pressure and cholesterol are in a good spot, the number on the scale is secondary.
Actionable Steps for Finding Your Healthy Range
Stop chasing a "perfect" number and start looking at these indicators instead.
- Check your energy levels. If you’re dieting down to a "target" weight but you’re too tired to climb a flight of stairs, you’re below your body's healthy threshold.
- Track your strength. Instead of tracking pounds lost, track how many pounds you can lift. Building muscle is the best thing a 5'2" woman can do for her long-term health.
- Get a DEXA scan if you’re curious. If you really want the data, skip the bathroom scale and get a Dual-Energy X-ray Absorptiometry scan. It tells you exactly how much of your weight is bone, how much is fat, and how much is muscle.
- Measure your waist. Keep a simple soft tape measure. Aim for a waist circumference of less than 35 inches to keep your metabolic risk low.
- Prioritize protein. For shorter women, every bite counts. Focus on high-quality protein to maintain the muscle you have.
The answer to what should a 5 2 woman weight isn't a single digit. It’s a range. It’s a feeling. It’s the ability to live your life without being tethered to a piece of plastic on the bathroom floor.
Focus on functional health. Eat for vitality. Move for joy. Let the weight settle where it naturally falls when you are taking the best possible care of yourself.
