What is the waist to height ratio?

The waist-to-height ratio, commonly known as the waist-to-stature ratio (WSR), is the waist circumference divided by height in the same units (metric or English). The WHtR is a fat distribution metric.

Using a stretchable tape, measure the waist circumference at the halfway between the last palpable rib and the top of the iliac crest.

Because it accounts for the distribution of abdominal fat, which is known to raise the aforementioned hazards, statistical data suggests that WHtR is a stronger predictor of cardiovascular, diabetes, and stroke risk than the body mass index (BMI).

In terms of cardiometabolic risk, abdominal fat has a greater impact on organs like the heart, liver, and kidneys than fat around the hips and bottom.

How to measure your waist to height ratio

To measure your waist to height ratio, follow these steps:

  1. Measure your waist circumference in centimeters.
  2. Measure your height in centimeters.
  3. Divide your waist circumference by your height.

Your waist to height ratio is the result of this calculation.

What is an ideal waist to height ratio?

Most health experts recommend a waist to height ratio of between 0.45 and 0.5 for optimal health. Guidelines published by the UK's National Institute for Health and Care Excellence suggest that adults should "ensure their waist size is less than half their height in order to help stave off serious health problems" (Source: The Guardian).
