What is a Pregnant Weight Gain Calculator?

A Pregnant Weight Gain Calculator estimates the recommended total weight gain during pregnancy based on:

• Pre-pregnancy weight
• Height (used to calculate BMI)
• BMI category
• Current trimester
• Singleton or multiple pregnancy (optional factor)

It provides a safe weight gain range aligned with medical guidelines.

How the Calculator Works

The tool uses standardized medical guidelines (commonly based on health organizations) to determine ideal weight gain ranges.

Step 1: BMI Calculation

BMI is calculated using:

BMI = weight (kg) ÷ height² (m²)

Step 2: BMI Category Identification

• Underweight
• Normal weight
• Overweight
• Obese

Step 3: Pregnancy Weight Gain Range

Each BMI category has a recommended total weight gain range.

Step 4: Trimester Breakdown

Weight gain is distributed differently across trimesters:

• First trimester: minimal gain
• Second trimester: steady gain
• Third trimester: continued gradual gain
