Calculate Pre-Pregnancy BMI and Recommended Weight Gain
Important: This calculator uses your pre-pregnancy weight and height to determine appropriate weight gain during pregnancy.
Weight Gain During Pregnancy: Recommended weight gain varies by pre-pregnancy BMI. These are ACOG (American College of Obstetricians and Gynecologists) guidelines. Underweight women should gain 28-40 lbs, normal weight 25-35 lbs, overweight 15-25 lbs, and obese 11-20 lbs. Always consult your obstetrician for personalized guidance.
