What this calculator does
BMI for women requires nuanced interpretation. Women naturally have 5-10% more body fat than men at equivalent BMI. Postmenopausal women experience increased abdominal fat.
How it works
BMI = weight(kg) / height(m)². Categories: underweight <18.5, normal 18.5-24.9, overweight 25-29.9, obese ≥30.
Formula
BMI = weight (kg) / height (m)². Research suggests 25-27 may be healthier for some women.
Tips for using this calculator
- Track waist circumference alongside BMI
- If pregnant, don't use standard BMI guidelines
- For women over 50, BMI 25-27 may offer protective effects
