BRI Calculator
Calculate Body Roundness Index.
Enter values to calculate your BRI.
The Body Roundness Index (BRI) is a more recent metric developed to estimate body fat and visceral fat percentage. It aims to provide a more accurate assessment of health risks associated with body shape compared to the traditional Body Mass Index (BMI).
The BRI Formula
BRI is calculated using height and waist circumference:
BRI = 364.2 - 365.5 × √(1 - (Waist Circumference / (2π))² / (0.5 × Height)²)
How to Interpret Your BRI
BRI values typically range from 1 to 16. A higher BRI value corresponds to a rounder body shape, which is often associated with a higher percentage of body fat and visceral adipose tissue. Increased visceral fat is a known risk factor for various health conditions, including cardiovascular disease and type 2 diabetes.
BRI vs. BMI
Unlike BMI, which only considers height and weight, BRI incorporates waist circumference. This is significant because waist size is a strong indicator of abdominal obesity (excess fat around the stomach), which is metabolically more dangerous than fat stored elsewhere. Therefore, BRI can sometimes provide better insight into weight-related health risks than BMI alone.
