How to measure waist-height ratio

  • Place the tape measure directly on your skin.
  • Measure your waist by placing the tape horizontally halfway between your lowest rib and the top of your hipbone.
  • Breathe out normally and take the measurement.
  • Hold the tape lightly so as to not compress your skin.
  • Measure your correct height by standing erect.
Waist Circumference is considered a risk factor for heart disease, irrespective of height and build, in the following cases:
  • Men: Over 94 cm (approx. 37 inches)
  • Women: Over 80 cm (approx. 31.5 inches)
For a person with a height of 1.7 meters or 170 cms (approx. 67 inches or 5ft and 7 inches) and a waist circumference of 0.8 meters or 80 cms (approx. 31.5 inches), the waist-to-height ratio would be approx. 0.47. This is below the threshold of 0.5, indicating that this individual's waist circumference is less than half of their height, which is often considered a healthy ratio in terms of obesity and related health risks.

This metric is praised for its simplicity, as it is an easy tool that can be used by both professionals and the general public in assessing health risks associated with obesity such as heart disease, diabetes, stroke, and hypertension(1 Trusted Source

Do remember not to confuse waist to height ratio with the 'Waist to Hip Ratio' which is used to measurebody fat distribution. Both, however, can be used to screen possible health problems. Waist circumference has a direct correlation with the risk of developing heart disease, because it measures the critical levels of fat accumulated between internal organs and the torso, that is, visceral fat. Visceral fat is directly connected to strokes and heart disease. Greater the waist circumference, the higher the morbidity and mortality from heart disease, diabetes, stroke and hypertension.
