1. What is WHtR?

The Waist-to-Height Ratio (WHtR) is a simple anthropometric measure of body fat distribution that compares waist circumference to height. It's a useful complement to BMI for assessing central obesity and associated health risks.

2. How Does the Calculator Work?

The calculator uses the WHtR formula:

Where:

• Waist Circumference — Measured at the midpoint between the lower rib and the top of the hip bone
• Height — Standing height measured without shoes

3. Importance of WHtR

Details: WHtR is a strong predictor of cardiovascular risk and metabolic syndrome. A ratio above 0.5 indicates increased health risks, regardless of BMI.

4. Using the Calculator

Tips: Measure waist circumference at the narrowest point between ribs and hips while standing. Enter both waist and height in centimeters for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy WHtR?
A: For adults, WHtR should be less than 0.5. Values between 0.5-0.6 indicate increased risk, and above 0.6 indicates high risk.

Q2: Is WHtR better than BMI?
A: WHtR may be better at predicting health risks as it accounts for central fat distribution, which is more metabolically active.

Q3: How to measure waist circumference accurately?
A: Use a flexible tape measure at the midpoint between the bottom of your ribs and top of your hips, keeping the tape horizontal.

Q4: Does WHtR apply to children?
A: Yes, but cutoff values differ by age. Generally, WHtR above 0.5 in children also indicates increased health risks.

Q5: Should WHtR replace BMI?
A: WHtR is a valuable complement to BMI but not necessarily a replacement. Both provide different information about body composition.
