About the Body Roundness Index (BRI) Calculator

Toolliyo's Body Roundness Index (BRI) Calculator is a free online tool that calculates your BRI, a measurement used to assess body shape and estimate visceral adiposity (abdominal fat).

What is Body Roundness Index (BRI)?

Body Roundness Index (BRI) is a formula that uses height and waist circumference to estimate the amount of visceral fat in your body. Visceral fat is located deep within the abdomen and is associated with increased health risks. The formula for BRI is:

BRI = 364.2 - 365.5 * √(height / waist) + 1.2 * waist

(where height and waist are in meters)

How to Use the Body Roundness Index (BRI) Calculator

To use this calculator, you will need the following measurements:

  1. Height: Enter your height in meters, centimeters, or inches.
  2. Waist Circumference: Measure your waist circumference at the narrowest point, in centimeters or inches.

Enter your height and waist circumference, and click the "Calculate BRI" button.

Understanding Your BRI Result

BRI values are interpreted as an indicator of body fat distribution, particularly visceral fat. Higher BRI values generally suggest a higher level of abdominal fat, which is associated with increased risks for:

  • Cardiovascular disease
  • Type 2 diabetes
  • Metabolic syndrome

There are no universally accepted "normal" or "ideal" BRI ranges. BRI should be interpreted in conjunction with other health indicators and a consultation with a healthcare professional.
