Review the results and growth chart

The calculator will show you whether your baby's weight is within the normal range for her age, and provide guidance on what to do if she's not meeting growth milestones.

Formula Used

The calculator uses standard pediatric growth charts to determine if your baby's weight is appropriate for her age. The formula for calculating weight-for-age percentiles is based on World Health Organization (WHO) growth standards.

Weight-for-age percentile = (Baby's weight / Median weight for age) × 100

Where the median weight for age is derived from WHO growth charts for infants.

Interpreting Results

The calculator will display your baby's weight percentile, which indicates where she falls in comparison to other babies of the same age:

Below 5th percentile: May indicate underweight
5th to 85th percentile: Normal weight range
Above 85th percentile: May indicate overweight

Note: Percentiles are not the same as percentages. A 50th percentile means your baby is at the 50th percentile of weight for her age, not that she weighs 50% of the average weight.

If your baby's weight percentile is outside the normal range, consult with your pediatrician to determine the cause and appropriate next steps.

Baby Growth Chart

The calculator includes a visual growth chart that shows your baby's weight compared to standard growth milestones. This helps you track her progress over time and identify any potential concerns.

Typical weight gain for babies includes:

First month: 10-20% of birth weight
Second month: 15-25% of birth weight
Each subsequent month: Approximately 10% of birth weight
