About Pregnancy Weight Gain Calculator
Calculate recommended total and weekly pregnancy weight gain based on pre-pregnancy BMI following ACOG (American College of Obstetricians and Gynecologists) guidelines. Shows week-by-week healthy weight range across all three trimesters.
Recommended pregnancy weight gain isn't a single universal number — it depends specifically on your pre-pregnancy BMI category, following guidelines from ACOG (American College of Obstetricians and Gynecologists): underweight women are generally advised to gain more total weight than overweight or obese women, since starting BMI significantly affects both maternal and fetal health outcomes at different gain levels. Weekly gain targets also differ by trimester — very little gain is expected in the first trimester with most of the recommended increase happening in the second and third. This tool calculates your personalized total and weekly recommended weight gain range based on your specific pre-pregnancy BMI category, following the ACOG framework.
