Bri-calculator
The BRI Calculator is a free, web-based tool that computes the Body Roundness Index (BRI) using a user's height and waist circumference, with optional age and gender inputs for more personalized context. It is designed to evaluate body shape "roundness" and provide an interpretation of potential health risks associated with obesity and abdominal fat distribution. The tool presents instant results, interprets them against researched thresholds, and provides average BRI values by age and gender from a 2024 study to help users compare their results.
