Pregnancy Weight Gain Calculator – Track & Maintain a Healthy Weight During Pregnancy
What is a Pregnancy Weight Gain Calculator?
The Pregnancy Weight Gain Calculator is an essential tool designed for expecting mothers to track their weight gain during each week of pregnancy. Maintaining the right weight gain is crucial for both the mother’s health and the baby’s development. This calculator provides personalized weight gain recommendations based on:
- Pre-pregnancy BMI (Body Mass Index)
- Current pregnancy stage (Weeks 1–40)
- Pregnancy with single or twin babies
By entering your height, pre-pregnancy weight, and current weight, you can determine if your weight gain is within the recommended range for a healthy pregnancy.
Recommended Pregnancy Weight Gain Based on Pre-Pregnancy BMI
The Institute of Medicine (IOM) provides guidelines for total weight gain during pregnancy, depending on pre-pregnancy BMI:
| Pre-Pregnancy BMI | Category | Recommended Total Weight Gain |
|---|---|---|
| < 18.5 | Underweight | 12.5 – 18 kg |
| 18.5 – 24.9 | Normal Weight | 11.5 – 16 kg |
| 25 – 29.9 | Overweight | 7 – 11.5 kg |
| ≥ 30 | Obese | 5 – 9 kg |
| Pregnant with Twins | Any BMI | 16 – 24 kg |
💡 For twin pregnancies, recommended weight gain is higher to support both babies’ growth.
This Pregnancy Weight Gain Tracker helps you understand how much weight you should gain each week and whether you are gaining weight too quickly or too slowly.
