Pregnancy Weight Gain
Track healthy weight gain during pregnancy
Gaining weight during pregnancy is healthy and necessary — but how much is 'on track' depends on your pre-pregnancy weight, height, and how far along you are. Our pregnancy weight gain calculator compares your current weight gain against medically recommended ranges for your stage of pregnancy.
This helps you have more informed conversations with your doctor and reduces the guesswork around whether your weight gain pattern is within a healthy range.
How This Calculator Works
The calculator uses your pre-pregnancy weight and height to determine your starting BMI category, then compares your current weight and week of pregnancy against the recommended cumulative weight gain range for that BMI category at this stage — giving you both your gain so far and the total expected range for a full-term pregnancy.
Why Use This Calculator
- Track whether your weight gain is on pace for your stage of pregnancy
- See both your progress so far and your full recommended range
- Personalized to your pre-pregnancy BMI category
- Helps guide conversations with your doctor or dietitian
