Pregnancy Weight Gain Calculator
Find the recommended total weight gain range for your pregnancy, based on your pre-pregnancy BMI.
How this is calculated
This uses the U.S. Institute of Medicine (IOM) guidelines for total pregnancy weight gain in a single-baby pregnancy, based on your pre-pregnancy BMI category. Twin or multiple pregnancies, and individual health conditions, change these ranges, so always confirm with your care provider.
