Waist-to-Height Ratio Calculator

What is the Waist-to-Height Ratio?

The Waist-to-Height Ratio (WHtR) is a simple measurement used to assess abdominal obesity and potential health risks. It's calculated by dividing your waist circumference by your height, both measured in the same units.

The Formula

The formula for calculating the Waist-to-Height Ratio is:

\[WHtR = \frac{Waist Circumference}{Height}\]

Where:

• WHtR: Waist-to-Height Ratio
• Waist Circumference: Measured at the narrowest part of the torso
• Height: Your total height

Calculation Steps

1. Measure your waist circumference and height in the same units (preferably centimeters)
2. Divide your waist circumference by your height
3. The result is your Waist-to-Height Ratio

Example Calculation

Let's calculate the WHtR for a person with a waist circumference of 85 cm and a height of 170 cm:

\[WHtR = \frac{85 cm}{170 cm} = 0.5\]

Visual Representation

This visual representation shows a person with a WHtR of 0.5, which falls in the overweight category. The red ellipse represents the waist circumference relative to the body height.

Interpreting the Results

The Waist-to-Height Ratio is interpreted as follows:

• Less than 0.4: Underweight
• 0.4 to less than 0.5: Healthy
• 0.5 to less than 0.6: Overweight
• 0.6 or higher: Obese

A WHtR of 0.5 or higher indicates increased health risks associated with abdominal obesity.
