Waist to Hip Ratio Calculator

WHR is a better predictor of heart-disease risk than BMI — especially for women in perimenopause, when fat shifts to the midsection.

Measure at the narrowest point, after exhaling.

Measure at the widest point of your hips/glutes.

Your WHR

0.80

Moderate risk

0.81–0.85 — slightly elevated risk. A small reduction in waist makes a real difference.

< 0.80Low risk
0.81 – 0.85Moderate
≥ 0.86High risk

WHR is one signal among many. Use alongside cycle, energy, and strength markers.

Why WHR matters more than the scale

Two women can weigh the same and have wildly different health risks depending on where their body stores fat. WHR captures the part the scale misses: abdominal (visceral) fat — the kind wrapped around your organs that drives heart disease, type 2 diabetes, and inflammation.

The menopause shift

Estrogen tells the body to store fat on the hips and thighs. As estrogen falls, storage moves to the belly — and a "pear" can become an "apple" in just a couple of years, even without weight gain.

What actually moves WHR

  • Strength training 2–3×/week reduces visceral fat specifically.
  • Protein at 1.6+ g/kg preserves muscle in a deficit.
  • Sleep under 6 hours raises cortisol → more belly fat.
  • Alcohol is a major driver of midsection fat in women 40+.

Measurement tips

Measure first thing in the morning, after the bathroom, before food or drink. Same tape, same spot, same time of day. Track monthly — daily noise hides the real trend.
