Frequently Asked Questions
What is waist-to-height ratio?
WHtR is your waist circumference divided by your height. It measures abdominal fat distribution, which is a key indicator of health risks.
What is a healthy WHtR?
A healthy WHtR is below 0.5, meaning your waist should be less than half your height. This is known as the "keep your waist to less than half your height" rule.
How do I measure my waist correctly?
Stand relaxed, breathe out normally, and measure around your waist at the midpoint between your lowest rib and the top of your hip bone.
Is WHtR better than BMI?
Many experts prefer WHtR because it accounts for fat distribution. BMI doesn't distinguish between muscle and fat or where fat is stored.
What health risks does WHtR predict?
High WHtR is associated with increased risk of heart disease, type 2 diabetes, high blood pressure, and metabolic syndrome.
