# Waist to Height Ratio Calculator

Experts are now claiming that your Waist/Height Ratio (WHtR) is a far more accurate way of measuring healthy weight than the traditional Body Mass Index (BMI). Not to be confused with your Waist/Hip Ratio (WHR), your WHtR calculates your body fat distribution and can be a significant early indicator of risk of diabetes, heart disease and stroke.

The calculation is equally valid for children as it is for adults.

Healthy Weight to Height Ratio

To measure the WHtR, simply record waist circumference, then divide that number by height.

• WHtR > 0.5
Higher risk of diabetes, heart disease, stroke and lower life span
• WHtR < 0.5
Considered healthy for both men and women worldwide

BMI Shortcomings

BMI is measured by a person’s weight in kilograms divided by the square of their height in meters – it is a complicated calculation and the formula is unfamiliar to most people. More importantly, the BMI doesn’t make allowances for the distribution of fat around the body.

Visceral Fat

Recently British scientists have revealed that a typical ‘apple’ shaped person, who carries excess abdominal fat (which sits close to the heart, liver and kidneys) is at far greater risk of health issues than a pear-shaped person, who typically carries weight on the hips, thighs and bottom.

Measuring someone’s waist is fundamental because it accounts for critical levels of fat that accumulate in between internal organs and the torso, aka visceral fat or ‘central obesity’. Visceral fat is directly linked to strokes and heart disease.

Example

Essentially: your waist should measure no more than half the length of your height

For a 6ft man (72 inches), this means having a waistline no larger than 36 inches, while a 5ft 4in (64 inch) woman’s waist should measure 32in or less. For people under the age of 40, a WHtR of over 0.50 is considered to put them at critical risk. For the over fifties the critical values start at 0.60.

Longer Lifespan

Another of the focuses of the study was on the accurate prediction of lifespan. It demonstrated that people with the highest WHtRs (whose waistlines measured 80% that of their height), lived on average 17 years less than their lower WHtR counterparts.

Dr Ashwell has also recommended that WHtR should be considered for use as a valuable screening tool, particularly for children as young as five, who are showing initial signs of excess weight gain, or whose lifestyle or heritage puts them at greater risk of obesity.
