Waist-to-Height Ratio Calculator

Keep your waist to less than half your height for optimal cardiometabolic health

❓ Frequently Asked Questions

What is a healthy waist-to-height ratio?
A WHtR below 0.5 is generally considered healthy for most adults. A ratio above 0.6 indicates significantly elevated cardiometabolic risk. The simplest way to remember: your waist should be less than half your height.
Is WHtR better than BMI?
Research consistently shows WHtR is a better predictor of cardiovascular disease, type 2 diabetes, and stroke than BMI. Unlike BMI, WHtR accounts for where fat is stored (abdomen vs. hips/thighs), which has a direct impact on organ health.
How do I measure my waist correctly?
Measure at the narrowest point of your torso, usually just above the navel, after exhaling normally. The tape should be snug but not compressing. For consistency, always measure at the same time of day.
What units should I use?
It doesn’t matter — as long as both measurements are in the same unit (both in cm, or both in inches), the ratio will be identical. The ratio is unitless.

Why Your Waist-to-Height Ratio Matters More Than BMI

The Waist-to-Height Ratio (WHtR) is increasingly recommended by cardiologists and endocrinologists as a superior obesity screening metric compared to BMI. While BMI only considers total weight relative to height, WHtR focuses specifically on abdominal adiposity — the type of fat stored around your organs, which is far more dangerous than subcutaneous fat elsewhere on the body.

The “Half Your Height” Rule

The most memorable health message from WHtR research is simple: keep your waist circumference to less than half your height. This corresponds to a WHtR of 0.5. Studies following hundreds of thousands of participants have found that people who maintain this ratio have significantly lower rates of:

  • Type 2 Diabetes
  • Hypertension (high blood pressure)
  • Coronary artery disease
  • Metabolic syndrome
  • All-cause mortality

WHtR Reference Ranges

  • Below 0.4: Very slim / possibly underweight
  • 0.40–0.49: Healthy and lean
  • 0.50–0.52: Acceptable — aim to reduce
  • 0.53–0.57: Overweight — action recommended
  • 0.58–0.62: Obese — medical advice advised
  • Above 0.63: Severely obese — high cardiovascular risk

How to Reduce Abdominal Fat

Waist circumference responds well to sustained caloric deficits combined with aerobic exercise. Visceral (abdominal) fat tends to be the first type lost with diet and exercise, making it one of the most responsive fat depots to lifestyle changes.
