🔬 Calculation Methodology
Our calculator uses LMS (Lambda-Mu-Sigma) method incorporating CDC growth charts. Percentiles compare measurements against 100 same-age, same-sex individuals. Height-for-age indicates linear growth status, while weight-for-age reflects body mass. BMI percentile is calculated using weight(kg)/height(m)² compared to reference data.
