What Is the Ideal Weight for 170 cm Women?
Using the WHO BMI standard (18.5–24.9), the healthy weight range for a 170 cm woman is 53.5 kg to 72.0 kg. The midpoint of this range — approximately 62.8 kg — corresponds to a BMI of 21.7, which falls comfortably in the healthy zone.
It's important to note that "ideal weight" is a range, not a single number. Within the healthy BMI range, your optimal weight depends on:
- Muscle mass: Muscular individuals can be healthy at the higher end or even slightly above
- Age: Slightly higher BMI (22–25) is associated with better outcomes in adults over 50
- Bone density: Larger bone structure supports higher healthy weight
- Ethnicity: Asian populations may have lower optimal BMI thresholds
