Waist-to-Height Ratio Calculation Results
How the calculation works
Waist-to-height ratio = waist circumference divided by height, using the same units. The adult screening bands used here are below 0.40 (lower than typical screening range), 0.40 to below 0.50 (below the common 0.50 threshold), 0.50 to below 0.60 (increased central adiposity screening range), and 0.60 or higher (higher central adiposity screening range). These are broad screening labels, not diagnoses.
Measure the waist around the midpoint between the lowest rib and top of the hip bone after a normal breath out. This tool is not intended for children, pregnancy or individual clinical decisions.
Frequently Asked Questions
What is waist-to-height ratio?
It is waist circumference divided by height, both measured in the same units.
What does a ratio of 0.50 mean?
It means your waist measures half your height. A ratio below 0.50 is a commonly used adult screening guide.
Where should I measure my waist?
Measure around the midpoint between the lowest rib and the top of the hip bone after breathing out normally.
Does this calculator diagnose a medical condition?
No. It is a screening estimate and does not diagnose disease.
Can I enter inches?
Yes. Select inches and enter both waist and height in inches.
Does this apply during pregnancy?
Waist-to-height ratio is not appropriate as a routine screening measure during pregnancy.
Is waist-to-height ratio better than BMI?
It provides different information about central fat distribution and may complement other health assessments.
