A healthy weight for a 5’2″ female falls between 102 and 136 pounds, based on the standard BMI range of 18.5 to 24.9 used by the CDC. That’s a wide window, and where you personally fall within it depends on your age, body composition, and how you carry your weight. The number on the scale is a starting point, not the full picture.
The Standard Healthy Range: 102 to 136 Pounds
The CDC defines a healthy weight using BMI categories that apply to all adults 20 and older, regardless of sex, age, or ethnicity. For someone who stands 5’2″, those categories break down like this:
- Underweight: 101 pounds or less (BMI below 18.5)
- Healthy weight: 102 to 136 pounds (BMI 18.5 to 24.9)
- Overweight: 137 to 164 pounds (BMI 25 to 29.9)
- Obese: 165 pounds or more (BMI 30 or higher)
These cutoffs come from the National Heart, Lung, and Blood Institute and are the same numbers your doctor would reference during a checkup. They’re useful as a general screening tool, but they don’t account for muscle mass, bone density, or where your body stores fat.
What Clinical Formulas Say
Doctors and pharmacists sometimes use “ideal body weight” formulas that were originally designed for medication dosing. Three of the most commonly cited ones give slightly different numbers for a 5’2″ woman:
- Devine formula: approximately 110 pounds
- Robinson formula: approximately 116 pounds
- Miller formula: approximately 123 pounds
These formulas were never meant to define the single “correct” weight for any person. They were created decades ago for narrow clinical purposes, and they tend to skew low compared to what modern research considers healthy. Still, the fact that all three land between 110 and 123 pounds gives you a rough midpoint within the broader 102 to 136 range.
Why the Range Is So Wide
A 34-pound spread between 102 and 136 might seem unhelpfully broad. But two women who are both 5’2″ can look and feel completely different at the same weight. Someone with more muscle mass will weigh more than someone with less, even if they wear the same clothing size, because muscle is denser than fat. A naturally broader frame carries weight differently than a narrow one.
Body fat percentage matters more than the scale alone. Women generally carry more body fat than men, and the amount shifts with age. Women in their late 40s average around 30% body fat, while women in their late 50s and beyond tend to stabilize closer to 43%. There’s no single validated threshold for what counts as “too much” body fat, which is part of why BMI remains the default screening tool despite its limitations.
Where You Carry Weight Matters More Than Total Weight
Fat stored around your midsection poses greater health risks than fat stored in your hips or thighs. A simple way to check this: your waist circumference should be less than half your height. For a 5’2″ woman (62 inches), that means keeping your waist measurement under 31 inches. This ratio, called waist-to-height ratio, is widely accepted as a quick screening tool for the kind of central fat that raises your risk of heart disease, high blood pressure, and type 2 diabetes.
You can measure this at home with a flexible tape measure placed around your bare waist, just above your hip bones. If you’re within the healthy BMI range but your waist exceeds 31 inches, the distribution of your weight may still carry metabolic risk. Conversely, if your weight lands a few pounds into the “overweight” category but your waist measurement is well under that threshold, your risk profile may be better than BMI alone suggests.
How Age Changes the Picture
The standard BMI categories were designed for adults of all ages, but research increasingly suggests they’re too restrictive for older women. A large study tracking elderly men and women found that the lowest mortality rates occurred not in the “healthy” BMI range of 18.5 to 24.9, but in a higher range. For women, the lowest risk of death was found at a BMI between 25 and 32.4, which for a 5’2″ woman translates to roughly 137 to 178 pounds.
Even more striking: a BMI below 25 in elderly adults was actually associated with increased mortality. The relationship between weight and health risk is U-shaped, and that curve shifts to the right as you age. This means carrying a bit of extra weight in your 60s and 70s appears protective rather than harmful, possibly because it provides reserves during illness or injury. If you’re over 65, the 102 to 136 range may be unnecessarily restrictive for you.
A Practical Way to Think About Your Weight
Rather than fixating on one number, it helps to use multiple data points together. Start with the BMI range of 102 to 136 as a general reference. Then check your waist measurement against the half-your-height guideline of 31 inches. Consider your age, since the “ideal” range appears to shift upward after 65. And pay attention to how you feel: your energy levels, how easily you move through daily activities, and whether your blood pressure and blood sugar are in normal ranges at your annual checkup.
A 5’2″ woman who weighs 140 pounds with a 29-inch waist, good blood pressure, and normal blood sugar is in a very different health position than one who weighs 125 pounds but has a 33-inch waist and elevated fasting glucose. The scale captures only one dimension of a much more complex picture.
