If you’re exactly five feet tall, you’ve probably spent a fair amount of time looking at those generic posters in a doctor's office or staring at a blinking cursor on a BMI calculator. It feels like the world is built for people who are 5'7", and when you're on the shorter side, every single pound shows up differently. It's frustrating. You eat one extra taco and suddenly your jeans feel tight, whereas your taller friends seem to have a much higher margin for error.
But here’s the thing. When people ask how much should a 5 foot female weigh, they are usually looking for a single, magic number. They want to hear "110 pounds" or "125 pounds" so they can either breathe a sigh of relief or start a new diet. Real health doesn't actually work like that.
The medical community often points to the Body Mass Index (BMI) as the gold standard. For a woman who stands 5'0" (60 inches), the "normal" BMI range falls between 18.5 and 24.9. In actual weight, that translates to roughly 95 to 128 pounds. That is a 33-pound gap. It’s huge! Think about that. A woman weighing 97 pounds and a woman weighing 127 pounds are both technically "normal" according to the CDC, yet they would look and feel incredibly different.
Why the "Ideal" Weight is Mostly a Myth
The Hamwi formula is an old-school method some clinicians still use to find "Ideal Body Weight" (IBW). It suggests that for a woman who is 5 feet tall, the baseline is 100 pounds. Then, you add five pounds for every inch over five feet. Since we are looking at exactly 5'0", the formula just spits out 100 pounds.
Honestly? That’s kinda ridiculous for most grown women.
A 100-pound target doesn't account for whether you have the bone structure of a bird or a powerlifter. It ignores your age. It ignores your muscle mass. If you have been lifting weights for five years and have a solid foundation of muscle, trying to hit 100 pounds might actually be dangerous or, at the very least, completely unsustainable.
Muscle is dense. It takes up less space than fat but weighs more on the scale. This is why you see women who weigh 130 pounds looking "leaner" than women who weigh 115 pounds but have very little muscle tone. This phenomenon is often called "skinny fat," though that’s a bit of a harsh term. It basically means you have a high body fat percentage even if your total weight is low.

The Frame Size Factor
You’ve probably heard people say they are "big-boned." People used to laugh at that, but there is some medical truth to it. Frame size is a real thing. To figure yours out, you can actually measure your wrist. For a woman under 5'2", a wrist circumference of less than 5.5 inches usually indicates a small frame. Between 5.5 and 5.75 inches is medium, and anything over 5.75 inches is a large frame.
If you have a large frame, your "healthy" weight is naturally going to be at the higher end of the BMI spectrum. If you try to force a large-framed body into a 100-pound box, you’re going to feel lethargic, cold, and probably pretty miserable.
Understanding BMI Limitations for Shorter Women
The BMI was created in the 1830s by a Belgian mathematician named Lambert Adolphe Jacques Quetelet. He wasn't a doctor. He was a statistician. He specifically stated that the BMI should not be used to diagnose the health of an individual, yet here we are, nearly 200 years later, using it as the primary metric for health insurance and doctor visits.
For shorter women, the BMI can be particularly wonky. Some researchers, like Nick Trefethen from Oxford University, argue that the standard BMI formula ($weight / height^2$) actually discriminates against short people. He proposed a "New BMI" ($1.3 \times weight / height^{2.5}$) because the traditional math doesn't scale correctly with height. Under the traditional formula, short people are often told they are "healthier" than they might actually be, whereas tall people are told they are "overweight" when they are just large humans.
Wait, it gets more complicated.
Body fat distribution matters way more than the number on the scale. A 2012 study published in the Journal of the American College of Cardiology found that people with a "normal" BMI but high belly fat (central obesity) had a higher risk of death than those who were technically "obese" but had their fat distributed elsewhere.

If you are 5'0" and 135 pounds but carry all your weight in your hips and thighs (pear-shaped), you might be metabolically healthier than a 5'0" woman who is 115 pounds but carries it all in her midsection.
The Role of Age and Menopause
Let's talk about the 40-plus crowd. Your weight at 22 is rarely going to be your weight at 52.
As women age, particularly through perimenopause and menopause, estrogen levels drop. This causes a shift in where the body stores fat. It moves from the hips to the abdomen. At the same time, we naturally lose muscle mass (sarcopenia) unless we are actively fighting it with resistance training.
A 5-foot female in her 50s might find that her "happy weight" is closer to 125 or 130 pounds. And that’s okay. In fact, some research suggests that having a slightly higher BMI in old age can be protective against osteoporosis and can provide a "reserve" if you get seriously ill. Being 105 pounds at age 70 might actually be a risk factor for bone fractures.
What about pregnancy?
If you're five feet tall and pregnant, the "standard" 25-35 pound weight gain recommendation can feel like a lot on a small frame. Because there is less vertical space, that weight puts a significant strain on the lower back and pelvic floor. It's always best to work with an OBGYN who understands that "one size fits all" doesn't work for shorter statures.
Practical Ways to Measure Progress (Without the Scale)
If the scale is a liar—or at least a very biased narrator—how do you actually know if you’re at a healthy weight?

- Waist-to-Height Ratio (WHtR): This is becoming the preferred metric for many experts. Take your waist measurement (at the narrowest point) and divide it by your height in inches. For a 5-foot woman (60 inches), your waist should ideally be 30 inches or less. This is a much better predictor of cardiovascular health than BMI.
- Energy Levels: Do you wake up tired? Do you crash at 3 PM? If you are undereating to maintain a "goal weight," your body will tell you by shutting down non-essential functions like your sex drive, your mood stability, and your hair growth.
- Clothing Fit: How do your clothes feel? If your "goal weight" requires you to never eat a piece of cake again and spend two hours on a treadmill daily, it’s not your goal weight. It’s a prison.
- Blood Work: Get your fasted glucose, HbA1c, and lipid panel done. If your numbers are perfect, but the scale says you're 135 pounds, your body is doing just fine.
The Psychological Impact of the "Petite" Label
There is a lot of societal pressure on shorter women to be "dainty." We see it in media and fashion all the time. This creates an internalised belief that if you aren't tiny, you've failed at being petite.
It's a trap.
I’ve seen women who are 5'0" and 140 pounds who look like absolute powerhouses because they cross-train and eat for performance. I’ve also seen women who are 5'0" and 105 pounds who struggle with brain fog and constant fatigue because they are over-restricting.
Health is a feeling, not a look.
Actionable Steps for Finding Your Healthy Weight
Stop chasing a number you saw on a chart from the 1970s. Instead, focus on these specific markers to find where your body actually wants to be.
- Measure your waist-to-height ratio. Grab a tape measure. If your waist is more than half your height, focus on nutritional quality and movement rather than just "losing weight."
- Prioritize protein. For shorter women, it’s easy to overconsume carbs and fats because our total calorie needs are lower. Aiming for 0.8 to 1 gram of protein per pound of lean body mass helps preserve muscle and keeps you full.
- Start lifting heavy things. Since shorter women have lower Basal Metabolic Rates (BMR), building muscle is the best way to "increase" your metabolism. It allows you to eat more while maintaining a leaner physique.
- Check your labs. Ask your doctor for a full metabolic panel. Use those results as your "scale." If your blood pressure and blood sugar are in the optimal range, you are likely at a weight that your body can handle.
- Audit your relationship with the scale. If weighing yourself every morning ruins your mood, throw the scale away. Use a pair of non-stretch denim jeans as your barometer instead.
The answer to how much should a 5 foot female weigh is ultimately found in the balance between your metabolic health, your physical strength, and your mental well-being. If you are 115 pounds but obsessed with every calorie, you aren't healthy. If you are 130 pounds, vibrant, strong, and your blood work is clean, you’ve found your "ideal" weight. Focus on the habits, and the weight will eventually settle exactly where it belongs for your unique biology.
