Why is waist-height ratio important?

The waist to height ratio is a measure of the distribution of body fat. Higher values of waist-height ratio indicate a higher risk of obesity-related cardiovascular diseases since it is correlated with abdominal obesity. Studies have found that waist-height ratio is a good indicator of the risk of heart attack, stroke or death, yet it hasn't been proved to measure the risk of diabetes. Other indicators of abdominal obesity are body mass index (BMI) and waist-hip ratio. Based on the waist to height ratio, you can allocate yourself to one of these groups:

  • Extremely slim - <0.34 both for men and women
  • Healthy - 0.43 to 0.52 for men and 0.42 to 0.48 for women
  • Overweight - 0.53 to 0.57 for men and 0.49 to 0.53 for women
  • Very overweight - 0.58 to 0.62 for men and 0.54 to 0.57 for women
  • Morbidly obese - >0.63 for men and >0.58 for women

How to measure your waist?

According to the WHO's data gathering protocol, the waist circumference should be measured at the midpoint between the last palpable rib and the top of the iliac crest, using a stretch‐resistant tape.

Practically, the measurements are usually taken at the smallest circumference of the natural waist, usually just above the belly button.

What does waist to height ratio calculator do?

The waist-height ratio is calculated as waist measurement divided by height measurement W ÷ H. For example, a person with a 28 in (71 cm) waist and 5 ft 7 in (170 cm) height has a waist–height ratio of 0.42.
