What Is a WHO Weight Percentile Calculator?
A WHO Weight Percentile Calculator is an online growth assessment tool that estimates a child’s weight percentile using:
- Age in months
- Weight in kilograms
- Gender (boys or girls)
The calculator compares entered values with general WHO growth standards to determine how a child’s weight compares with children of the same age and gender.
For example:
- A child in the 50th percentile is considered average for their age group.
- A child below the 5th percentile may be considered underweight.
- A child above the 95th percentile may be at risk of overweight.
The tool is useful for quickly understanding growth patterns and monitoring child development over time.

Understanding Weight Percentiles
Weight percentiles help compare a child’s weight with other children of the same age and gender.
Here is a simple explanation:
| Percentile | Meaning |
|---|---|
| Below 5th | Underweight |
| 5th–84th | Healthy Weight |
| 85th–94th | Risk of Overweight |
| 95th and above | Overweight |
For example:
- If a child is in the 60th percentile, they weigh more than 60% of children in the same group.
- If a child is in the 10th percentile, they weigh more than 10% of children their age.
Percentiles are tools for growth monitoring and should not be used alone to diagnose medical conditions.
Practical Example 1: Monitoring Infant Growth
