About the Waist-to-Height Ratio Calculator

Waist-to-Height Ratio is treated here as a quantitative relation between Waist Circumference and Height and Waist-to-Height Ratio, Risk Category and Maximum Healthy Waist for Your Height.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
WHtR = Waist Circumference / Height
(both in the same units - cm or inches)
Healthy Maximum Waist = Height x 0.50
Threshold: WHtR < 0.50 is generally healthy for adults of all ages and both sexes.

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

WHtR = Waist Circumference / Height
(both in the same units - cm or inches)
Healthy Maximum Waist = Height x 0.50
Threshold: WHtR < 0.50 is generally healthy for adults of all ages and both sexes.

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Healthy Adult, 175 cm, 83 cm waist

Inputs

waist_cm: 83 height_cm: 175
Waist-to-Height Ratio: 0.47. Risk Category: Healthy. Maximum Healthy Waist for Your Height: 87.5 cm

With Waist Circumference = 83 and Height = 175 as the stated inputs, the result is Waist-to-Height Ratio = 0.47, Risk Category = Healthy and Maximum Healthy Waist for Your Height = 87.5 cm. Each value corresponds to the declared output fields.

Example 2: Borderline — 170 cm, 86 cm waist

Inputs

waist_cm: 86 height_cm: 170
Waist-to-Height Ratio: 0.51. Risk Category: Overweight. Maximum Healthy Waist for Your Height: 85 cm

With Waist Circumference = 86 and Height = 170 as the stated inputs, the result is Waist-to-Height Ratio = 0.51, Risk Category = Overweight and Maximum Healthy Waist for Your Height = 85 cm. Each value corresponds to the declared output fields.

Example 3: High-Risk Individual, 168 cm, 105 cm waist

Inputs

waist_cm: 105 height_cm: 168
Waist-to-Height Ratio: 0.63. Risk Category: Very High Risk. Maximum Healthy Waist for Your Height: 84 cm

With Waist Circumference = 105 and Height = 168 as the stated inputs, the result is Waist-to-Height Ratio = 0.63, Risk Category = Very High Risk and Maximum Healthy Waist for Your Height = 84 cm. Each value corresponds to the declared output fields.

Example 4: Tall Person — 190 cm, 93 cm waist

Inputs

waist_cm: 93 height_cm: 190
Waist-to-Height Ratio: 0.49. Risk Category: Healthy. Maximum Healthy Waist for Your Height: 95 cm

With Waist Circumference = 93 and Height = 190 as the stated inputs, the result is Waist-to-Height Ratio = 0.49, Risk Category = Healthy and Maximum Healthy Waist for Your Height = 95 cm. Each value corresponds to the declared output fields.
