About this tool

Planned: a pregnancy weight gain calculator using the Institute of Medicine / ACOG ranges by pre-pregnancy BMI, with a full 40-week table and a twins mode. Every rival is a small site, but this is the most sensitive health topic in the portfolio, so it launches only with the guidelines cited exactly and a clear follow-your-midwife disclaimer.

Frequently asked questions

How much weight should I gain in pregnancy?

IOM/ACOG total-gain ranges depend on pre-pregnancy BMI: about 12.5–18 kg if underweight, 11.5–16 kg if a healthy weight, 7–11.5 kg if overweight, 5–9 kg if obese — more for twins.

Is this calculator medical advice?

No. It reproduces published guideline ranges for information only; your own care team may set a different target, and theirs wins.
