Estimate your recommended pregnancy weight gain using the Institute of Medicine guidelines, which base the target range on your pre-pregnancy body mass index. Healthy weight gain supports your baby growth while keeping risks lower for both of you, and the guidelines set different ranges for underweight, normal weight, overweight and obese starting points. This tool takes your height and pre-pregnancy weight to compute your BMI category, then shows the total recommended gain for a single pregnancy along with an expected range for your current week, since most gain happens in the second and third trimesters. Enter your height, starting weight, current weight and week of pregnancy to see where you sit against the guideline range. Everything is calculated in your browser, and this is general information, not medical advice. Your provider will personalize targets for twins, medical conditions and your individual situation.
