The waist to hip ratio calculator helps to find out your body shape (pear or apple) and determines your risks for heart disease.

Waist to Hip Ratio:
Health risk level:


The waist-to-hip ratio compares your waist measurement to your hip measurement. Higher ratios can mean you have more fat around your waist. This can lead to a higher risk for heart disease or diabetes.


The waist–hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips. This is calculated as waist measurement divided by hip measurement (W⁄H).

The medical value of waist measurement was triggered by Devendra Singh, an evolutionary biologist from the University of Texas, who theorised that the waist-hip ratio (WHR) was a marker of oestrogen concentration in women. Much later the concept of visceral fat emerged.

The following chart shows how the WHO classify the risk of being affected by weight related health conditions according to WHR:

Health risk Men Women
Low 0.95 or lower 0.80 or lower
Moderate 0.96-1.0 0.81-0.85
High 1.0 or higher 0.86 or higher

Those with a high WHR carry weight around their middle, so their body shape may be described as an “apple.”

Research shows people who are “apple-shaped” are at a greater risk of certain health conditions than those who are “pear-shaped” (when the hips are wider than the upper body).

These health conditions include:

  • Cardiovascular diseaseOne studyTrusted Source  found that abdominal obesity increased the risk of cardiovascular disease and cancer. Another studyTrusted Source  found the WHR predicted cardiovascular disease more effectively than BMI or waist circumference. A third studyTrusted Source  found that WHR is a better indicator of risk of mortality from cardiovascular disease than waist circumference alone.
  • Type 2 diabetes: A 2016 studyTrusted Source  found that an increased waist circumference was linked to an increased risk of type 2 diabetes.
  • Fertility: A 2002 study found that women with a WHR of over 0.80 have a lower pregnancy rate than those with a lower WHR, regardless of their BMI.

As well as using WHR to indicate how likely someone is to develop certain health conditions; it may also be used to indicate obesity. According to WHO:

  • a WHR of over 0.85 indicates obesity in women
  • a WHR of over 0.90 indicates obesity in men
