Waist-to-Hip Ratio Calculator
Waist-to-hip ratio compares midsection size to hip size. For women, higher ratios are often discussed alongside cardiovascular and metabolic risk in population studies—your clinician still interprets your personal risk.
Stand relaxed. Waist is usually the narrowest horizontal line between ribs and hip bones; hip is the widest part around your seat. Keep the tape level front-to-back.
Narrowest torso circumference you can find consistently.

These bands summarize large groups, not your individual medical fate. Follow up on blood pressure, lipids, and family history with a clinician.

Important usage notes & limitations
Reproductive timelines interact with contraception cessation, PCOS phenotype, transgender hormone therapy intensity, low body-fat athletic amenorrhea, and perimenopause. Hormonal contraception intentionally suppresses natural ovulatory signals until washout stabilization — calendar methods become meaningful only once cycles resume reliably.
