Estimate recommended pregnancy weight gain based on pre-pregnancy weight, height, BMI category, pregnancy stage, and whether you are carrying one baby or multiples. This free pregnancy weight gain calculator shows total recommended gain, weekly guidance, and a practical progress range in a clean calculator layout.
Pre-pregnancy BMI:
The calculator estimates BMI from your pre-pregnancy height and weight.
Recommended range:
That BMI category is used to assign a common total pregnancy weight gain range.
Pregnancy stage:
The result also estimates what gain might look like by your current week of pregnancy.
Progress check:
Your current weight is compared against the practical target range for where you are now.
Pregnancy weight gain guidance can help put your progress into context during each stage of pregnancy. Many people use it as a reference point for appointments, tracking, and general planning.
It can be most helpful when used as a broad range rather than a strict day-to-day target.
Your result shows pre-pregnancy BMI, your recommended total gain range, a practical current target based on your week of pregnancy, and how your current gain compares.
This gives you both a full-pregnancy view and a progress-to-date view in one place.
