An excessive waistline may indicate high visceral fat, increasing the risk of chronic diseases. This tool calculates your Waist-to-Height Ratio (WHtR) using a simple formula: waist circumference (cm) divided by height (cm), providing an exact value and health risk assessment. WHtR is a key indicator of central obesity; a ratio of ≥0.5 suggests potential health risks.
What does a WHtR over 0.5 mean?
It indicates a higher risk of central obesity, meaning you should pay closer attention to your visceral fat levels and overall health.
What is the fundamental difference between WHtR and BMI?
While BMI reflects your overall body mass index, WHtR focuses specifically on abdominal fat accumulation. According to WHO research data, WHtR is 42% more sensitive in predicting cardiovascular disease risks and is not skewed by muscle mass.
Measure your waist circumference at the level of your belly button at the end of an exhale. Results are for reference only and cannot replace professional medical diagnosis. Entering values outside the supported range will cause the calculation to fail. For minors, it is recommended to use pediatric-specific assessment standards.
Clinical studies show that a WHtR ≥0.55 is associated with a 3-fold increase in diabetes risk. For example, a 170 cm tall male with an 85 cm waist has a WHtR of 0.5, which is borderline. If the waist reaches 95 cm (WHtR = 0.56), he enters the high-risk zone, and a body fat composition test is highly recommended.
