WHtR Calculator ( Waist-to-Height Ratio Calculator ) for Adults with Ideal Waist Circumference in Meters

optimal WHtR ratio Woman on weight machine , best waist circumference

The Waist to Height Ratio is a measure to analyse the ratio of the waist circumference in comparison to the body height.
With this index it is easy to find out the ideal distribution of fat for a specific height. It also can be identified if you are underweight or overweight. In the Metric measurement system the WHtR ratio number is measured by taking the waist circumference in Meters u and divided by the body height in Meters h.
WHtR = u/h.

WHtR values and and their meaning for adolescents up to 15 years:
WHtR value: Category:

< 0,34 Underweight

0,34 to 0,45 Optimal waist circumference, Optimal weight

0,46 to 0,51 Mild overweight, Pre-obesity

0,52 to 0,63 Strong overweight, Obesity Class I

> 0,63 Very strong overweight

WHtR value:	Category:
< 0,34	Underweight
0,34 to 0,45	Optimal waist circumference, Optimal weight
0,46 to 0,51	Mild overweight, Pre-obesity

WHtR values and and their meaning for adults and youth between 16 and 40 years.
WHtR value: Category:

< 0,40 Underweight

0,40 to 0,50 Optimal waist circumference, Optimal weight

0,51 to 0,56 Mild overweight, Pre-obesity

0,57 to 0,68 Strong overweight, Obesity Class I

WHtR values and and their meaning for adults and youth between 16 and 40 years.
WHtR value:	Category:
< 0,40	Underweight
0,40 to 0,50	Optimal waist circumference, Optimal weight
0,51 to 0,56	Mild overweight, Pre-obesity
0,57 to 0,68	Strong overweight, Obesity Class I
> 0,68	Very strong overweight

WHtR values and and their meaning for adults between 41 and 50 years:
WHtR value: Category:

< (0,40 + 0,01 * (Age-40)) Underweight

0,40 to 0,50 + 0,01 * (Age-40) Optimal waist circumference, Optimal weight

0,51 to 0,56 + 0,01 * (Age-40) Mild overweight, Pre-obesity

0,57 to 0,68 + 0,01 * (Age-40) Strong overweight, Obesity Class I

> (0,68 + 0,01 * (Age-40)) Very strong overweight

Example: A 47 years old adult has its optimal waist circumference, when its WHtR value is between 0,40 + 0,01 * (Age-40) and 0,50 + 0,01 * (Age-40). So the this specific optimum is reached between a Waist-to-height ratio of 0,47 to 0,57.

Several medical trials show a strong connection between abnormal Waist-to-Height Ratio (WHtR) values and your health factors. They found no such connection between the Body Mass Index (BMI) and health.
