Body Roundness Index Calculator
The Body Roundness Index (BRI) calculator helps assess body composition and health risks by measuring waist circumference relative to height. It provides insight into visceral fat distribution, offering a more specific health risk assessment than traditional BMI. BRI helps identify risks for obesity-related diseases like diabetes and cardiovascular conditions.

FAQs
What is Body Roundness Index?
Body Roundness Index (BRI) is a anthropometric measurement that estimates body fat distribution using waist circumference and height. Developed as an alternative to BMI, it better reflects abdominal obesity and associated health risks through geometric analysis of body shape. BRI values range from 0-12, with higher numbers indicating greater health risks.
How is BRI calculated?
BRI is calculated using the formula: 364.2 - 365.5 × √(1 - (Waist Circumference/(2 × Height))²). This complex formula accounts for the elliptical relationship between waist size and height, providing a more accurate assessment of body roundness and visceral fat distribution than simple ratios.
Is BRI better than BMI?
BRI offers advantages over BMI by specifically assessing abdominal obesity, a key factor in metabolic diseases. While BMI only considers weight-height ratio, BRI accounts for fat distribution. However, both metrics have value and should be used alongside other health assessments for comprehensive evaluation.
What's a healthy BRI range?
A BRI of 0-3 indicates low health risk, 3-6 moderate risk, and 6+ high risk. These ranges help identify potential for obesity-related conditions. However, individual health assessments should consider multiple factors including age, gender, and medical history for accurate interpretation.
