Weekly Pregnancy Weight Gain Calculator

This pregnancy weight gain calculator is used to estimate how much weight you will and should gain during pregnancy. Use this week-by-week pregnancy weight gain as an appropriate weight guide. Most women gain between 8kg-20kg during a pregnancy for a single baby. Weight gain during pregnancy is not just attributed to the weight of the fetus. Most of the weight gain goes to the development of tissues that allow fetal development, growth, and prepare the body for breastfeeding.
