1. What is WHtR?

The Waist-to-Height Ratio (WHtR) is a simple measure of central obesity that compares waist circumference to height. It's considered by many as a better predictor of health risks than BMI alone, especially for cardiovascular disease and diabetes.

2. How Does the Calculator Work?

The calculator uses the WHtR formula:

And also calculates BMI using:

Interpretation:

• WHtR ≥ 0.5 indicates increased health risks
• BMI categories: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), Obese (≥30)

3. Importance of WHtR and BMI

Details: WHtR is particularly good at identifying central obesity, which is a major risk factor for metabolic syndrome, while BMI provides a general measure of body fatness.

4. Using the Calculator

Tips: Measure waist at the narrowest point between ribs and hips. Stand straight and measure height without shoes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why use WHtR instead of just BMI?
A: WHtR better accounts for fat distribution, particularly dangerous abdominal fat that BMI might miss in "normal weight" individuals.

Q2: What are healthy WHtR ranges?
A: Generally, keep WHtR below 0.5. Some suggest below 0.6 for older adults.

Q3: How should I measure my waist accurately?
A: Measure at the narrowest point between ribs and hips, or midway if not obvious. Measure after exhaling normally.

Q4: Are there limitations to WHtR?
A: Like BMI, WHtR doesn't distinguish between muscle and fat. Very muscular individuals may have high ratios without excess fat.

Q5: Should children use this calculator?
A: WHtR and BMI interpretations differ for children. Pediatric-specific calculators should be used for those under 18.
