About BMI Calculator Web
We provide free, evidence-based BMI screening tools to help adults understand body weight categories with appropriate physiological context. No data leaves your device.
Our Mission: Evidence-Based & Inclusive
Founded in 2024, BMI Calculator Web was built to correct a major flaw in generic BMI calculators: they ignore biological sex differences in body composition (e.g., muscle mass, fat distribution). Research from NIH shows that gender-specific interpretation improves risk stratification for metabolic syndrome.
Our commitment: Every BMI result includes a gender-contextual note based on established medical literature, not stereotypes. We follow the WHO BMI classification for adults (≥18 years) and provide specialized calculators for athletes, seniors, pregnant women, children, and Asian populations.
