How to Use This Calculator
Measure carefully
Use consistent tools for height and weight. Toggle between metric and imperial units as preferred.
Interpret the BMI band
BMI is a screening tool. Women with low muscle mass or high bone density may see different risk profiles than the BMI alone suggests.
Pair with other indicators
Consider waist circumference, body composition, menstrual health, and lab markers to inform next steps.
Formula
BMI = Weight ÷ Height²
- Metric: weight (kg) ÷ [height (m)]²
- Imperial: weight (lb) ÷ [height (in)]² × 703
- Apply the same formula for women and men—interpretation considers context such as pregnancy or menopause.
Understanding BMI in Women
BMI screens for cardiometabolic disease, fertility challenges, and bone health risks. For women, waist circumference under 80 cm (31.5 in) is often recommended to minimize abdominal fat–related risk.
Underweight
BMI < 18.5 — monitor hormonal health, energy availability, and bone density.
Healthy weight
18.5 ≤ BMI < 25 — maintain balanced nutrition and strength training.
Overweight
25 ≤ BMI < 30 — track waist circumference and metabolic markers.
Obesity
BMI ≥ 30 — collaborate with healthcare professionals on comprehensive lifestyle support.
Frequently Asked Questions
Does BMI account for pregnancy or postpartum changes?
BMI is not suitable during pregnancy or immediately postpartum. Consult your obstetric provider for weight recommendations.
What waist size is recommended for women?
A waist circumference below 80 cm (31.5 in) is often cited as a threshold for lower metabolic risk in women.
How does menopause affect BMI interpretation?
Body composition changes around menopause. Combine BMI with waist measurements, bone health checks, and lab tests.
Should I rely solely on BMI?
No. BMI is an initial screen. Pair it with lifestyle review, clinical tests, and professional guidance for a complete assessment.
