BMI Z-Score Calculator

This tool allows you to calculate the body mass index (BMI) of your patients between the ages of 2 and 20 years, as well as the exact BMI percentile and z-score (standard deviation), based on the Center for Disease Control (CDC) growth charts. Z-scores are particularly useful to monitor changes in patients with a BMI above the 99th percentile or below the 1st percentile.

All fields are required. Please enter a value for every field. The default unit values are kg and cm.

Please make sure the patient is between 2 and 20 years old
