Who Baby Boy Growth Chart Calculator

The WHO Baby Boy Growth Chart Calculator helps parents track their child's development using official World Health Organization standards. This tool provides accurate measurements for height, weight, and head circumference, allowing you to monitor your baby's growth against healthy development benchmarks.

How to Use This Calculator

Using the WHO Baby Boy Growth Chart Calculator is simple and straightforward:

Enter your baby's age in months or years
Input your baby's height in centimeters
Enter your baby's weight in kilograms
Input your baby's head circumference in centimeters
Click the "Calculate" button to see the results

The calculator will compare your baby's measurements against WHO growth standards and provide a visual chart showing where your baby stands in terms of development.

Note: The WHO growth charts are based on data from healthy babies. If your baby's measurements fall outside the normal range, consult with a pediatrician for personalized advice.

Understanding Growth Milestones

Tracking your baby's growth is essential for identifying any potential issues early. The WHO growth charts provide benchmarks for:

Height-for-age
Weight-for-age
Weight-for-length
Head circumference-for-age

Each measurement is categorized as:

Below average (red zone)
Average (green zone)
Above average (blue zone)

If your baby's measurements consistently fall in the red zone, it's important to consult with a healthcare professional to rule out any underlying issues.

Growth percentile = (Number of babies with measurements below yours / Total number of babies) × 100

WHO Growth Chart Comparison

Here's a comparison table showing typical growth measurements for boys at different ages:

Age	Height (cm)	Weight (kg)	Head Circumference (cm)
1 month	50-54	3.2-3.8	33-35
3 months	57-61	4.5-5.2	37-39
6 months	64-68	6.2-7.1	40-42
9 months	69-73	7.5-8.5	42-44
12 months	73-77	8.5-9.8	44-46

These are approximate ranges. Individual variations are normal, and these measurements should be used as general guidelines rather than strict targets.
