You’re standing there at five-foot-six. Maybe you’re looking at a chart in a sterile doctor’s office, or maybe you’re just staring at the floor, wondering why that little digital number feels like a personal grade on your character. It’s a common height. Average, really. But the "right" number for a 5'6 woman healthy weight isn't a single point on a line. It’s more like a broad, messy landscape that changes depending on whether you’ve got dense bones, a penchant for lifting heavy things, or if you’re just built like a marathon runner.
Most medical professionals point straight to the Body Mass Index (BMI). It’s the old standard. Developed by Lambert Adolphe Jacques Quetelet in the 1830s—yeah, the 1830s—it was never meant to be a diagnostic tool for individuals. Yet, here we are. For a woman who is 5'6", the "normal" BMI range falls between 115 and 154 pounds.
That’s a 39-pound gap.
Think about that. You could lose the weight of a medium-sized dog and still be within the "healthy" bracket. It’s wild. But it also shows how much wiggle room there actually is.
What the charts don't tell you about being 5'6"
If you’re 150 pounds and fit, you look radically different than if you’re 150 pounds and sedentary. Muscle is dense. It’s compact. It’s heavy. When people search for a 5'6 woman healthy weight, they’re often looking for a target to hit, but the scale doesn't know the difference between a liter of water, a pound of bicep, or a pound of visceral fat.
Take "Skinny Fat." It’s a harsh term, honestly. But it describes a very real metabolic state where a person's weight is low, but their body fat percentage is high. You could be 125 pounds—the "ideal" according to some 1950s height-weight tables—and still have high cholesterol or poor insulin sensitivity. On the flip side, an athlete at 5'6" might weigh 160 pounds, technically "overweight" by BMI standards, yet have a resting heart rate of 50 and perfect blood pressure.
Frame size matters too. Grab your wrist with your thumb and middle finger. Do they overlap? Touch perfectly? Or is there a gap? This isn't high science, but it’s a quick way to gauge if you have a small, medium, or large frame. A woman with a large frame and a 5'6" stature might feel like she’s starving at 130 pounds, whereas a small-framed woman might feel sluggish and heavy at 145.

The role of age and hormones
We need to talk about the "menopause spread." It’s real. As women age, especially moving into their 40s and 50s, the body naturally shifts. Estrogen drops. Muscle mass tends to decline unless you’re actively fighting it with resistance training.
A healthy weight for a 22-year-old 5'6" woman might not be the same as it is for a 65-year-old. In fact, some geriatric research suggests that carrying a little extra weight as you age can be protective against osteoporosis and can provide a "reserve" if you get hit with a serious illness. The obsession with the lowest possible number can actually become a health risk later in life.
And then there's the lifestyle factor.
Do you walk to work? Do you sit at a desk for nine hours? Are you chasing toddlers? A 5'6" woman who is highly active might need to maintain a higher weight just to fuel her activity levels and keep her hormonal health in check. Amenorrhea—losing your period—can happen if your weight drops too low for your activity level, even if the scale says you’re in the "healthy" zone.
Better metrics than the scale
Since we know the scale is a bit of a liar, what should you actually look at?
- Waist-to-Hip Ratio: This is a big one. It measures where you store your fat. Fat stored around the midsection (visceral fat) is much more dangerous for your heart than fat stored on the hips and thighs. For a woman, a ratio of 0.85 or lower is generally considered healthy.
- The "Pants Test": Honestly, how do your clothes fit? Are you energetic? Can you climb two flights of stairs without gasping for air? These functional markers tell you more about your health than a number ever will.
- Blood Work: You can't see your A1C or your lipid profile in the mirror. A 5'6 woman healthy weight is ultimately one that supports healthy internal biomarkers.
I once talked to a nutritionist who said the "ideal" weight is the one where you feel your best, your labs are clean, and you aren't miserable maintaining it. If you have to starve yourself to stay at 130, that isn't your healthy weight. It’s a prison.

Real-world examples of the 5'6" experience
Let's look at three hypothetical but realistic profiles.
First, there's Sarah. She’s 5'6", 135 pounds. She does yoga and eats a mostly plant-based diet. She looks "fit" in the traditional sense. Her BMI is 21.8. Perfect, right? For her, yes.
Then there's Elena. She’s a powerlifter. Also 5'6", but she weighs 165 pounds. Her BMI is 26.6, which puts her in the "overweight" category. But she has 22% body fat, which is athletic for a woman. She’s metabolically healthier than many people twenty pounds lighter than her.
Finally, consider Maya. She’s 5'6" and 150 pounds. She’s a "medium" build. She’s not an athlete, but she walks her dog and eats balanced meals. She’s stayed the same weight for ten years. Her doctors are happy because her blood pressure is 110/70.
All three of these women are at a healthy weight.
Moving beyond the "Goal Weight" mentality
We’ve been conditioned to pick a "goal weight" and obsess over it. But your body isn't a static object. It's a biological system. Your weight will fluctuate by three to five pounds every single week just based on salt intake, your menstrual cycle, and inflammation.

If you’re 5'6" and trying to find your sweet spot, stop looking at the 115-154 range as a target and start looking at it as a playground. Where in that range does your body want to settle when you're eating enough protein, getting your vegetables, and moving your body in ways you actually enjoy?
Often, the "healthy" weight is simply the byproduct of healthy habits, not the goal itself.
Actionable steps for finding your personal healthy weight
If you're feeling lost in the numbers, try these shifts. They work better than staring at a BMI chart.
- Prioritize Protein: Aim for roughly 0.7 to 1 gram of protein per pound of your target weight. This helps preserve the muscle that actually makes you "look" fit and keeps your metabolism humming.
- Throw Away the "Goal Weight" Mentality: Instead, set a "Goal Feeling." Do you want to feel strong? Energetic? Rested?
- Track Trends, Not Days: If you must weigh yourself, use an app that calculates a moving average. This smooths out the daily water weight spikes that can mess with your head.
- Check Your Waist: Take a measuring tape. Measure at the narrowest part of your waist. If it’s under 35 inches, your risk for weight-related chronic diseases is significantly lower, regardless of what the total weight is.
- Strength Train: Even twice a week. It changes the composition of your 5'6" frame. You might stay the same weight but drop two dress sizes. That’s the magic of body recomposition.
Ultimately, being a 5'6" woman is an advantage. You’re tall enough to carry weight well and have a decent basal metabolic rate, but not so tall that finding clothes is an impossible nightmare. Use that height. Build some muscle. Eat real food. The "healthy weight" will usually take care of itself once you stop trying to force it into a tiny, outdated box.
Focus on the metrics that actually matter—your strength, your sleep quality, and your metabolic health. The number on the scale is just one tiny data point in a much larger, much more interesting story about your life.
