Pregnancy weight gain calculator

Healthy weight gain in pregnancy depends on your pre-pregnancy BMI and how far along you are. This calculator works out your BMI, your gain so far, and the expected range for your week using the 2009 Institute of Medicine guidelines for a single baby.

Enter your numbers, drag the week slider, and see at a glance whether your gain is on track — all privately in your browser.
