What is BMI for Women?

BMI for women uses the same formula used for all adults. It helps estimate whether weight falls within a typical healthy range, though it does not directly measure body fat.

BMI Formula for Women

Metric: BMI = weight (kg) ÷ height² (m²)

Imperial: BMI = (weight (lbs) ÷ height² (in²)) × 703

Why BMI Is Only One Health Indicator

BMI does not account for body composition, fat distribution, or hormonal and metabolic differences. It works best as a general screening tool rather than a diagnosis.

BMI Categories for Women

Category	BMI Range	Health Risk
Underweight	< 18.5	Possible nutritional deficiency
Normal Weight	18.5 – 24.9	Low risk
Overweight	25 – 29.9	Moderate risk
Obese	≥ 30	High risk
