In this guide, we will walk you through how to use this growth calculator effectively, explain its features, and provide practical tips on interpreting the results. Whether you’re a parent concerned about your child’s growth or a health professional seeking a quick way to assess growth, this tool will help you make informed decisions.
How to Use the WHO Growth Chart Calculator
Using the WHO Growth Chart Calculator is simple and straightforward. Here’s a step-by-step guide to help you get started:
Step 1: Open the Calculator
Start by accessing the WHO Growth Chart Calculator on your device. It’s a web-based tool that requires no downloads.
Step 2: Enter Basic Information
- Age (Months):
Input the child’s age in months. This is a critical factor in determining growth standards since WHO growth charts are segmented by age. - Weight (kg):
Enter the child’s weight in kilograms. This is essential for calculating the weight-for-age Z-score. - Height (cm):
Enter the child’s height in centimeters. This is used to calculate the height-for-age Z-score. - Gender:
Select the child’s gender (Male or Female). Gender is an important factor in growth assessment since boys and girls grow at different rates during certain stages.
Step 3: Calculate Growth
Once all the details are filled in, click the “Calculate Growth” button. The tool will process the data and provide a comprehensive report showing how the child’s growth compares to global standards.
Step 4: Review the Results
After a brief processing time, the results will appear on the screen, displaying the following key growth metrics:
- Weight-for-Age Z-score
- Height-for-Age Z-score
- Weight-for-Height Z-score
These scores represent how the child’s growth compares to other children of the same age and gender worldwide.
Step 5: Save or Share Results
Once you have the results, you can:
- Copy Results: Easily copy the data for further use or to share with a healthcare provider.
- Share Results: If you’re using a compatible browser, you can directly share the results via social media or messaging apps.
Example: Using the WHO Growth Chart Calculator
Let’s go through an example to better understand how the tool works. Suppose you have a 12-month-old child weighing 9 kg and measuring 75 cm in height. Here’s how to proceed:
- Age (Months): Enter “12”.
- Weight (kg): Enter “9.0”.
- Height (cm): Enter “75”.
- Gender: Select “Male”.
After clicking “Calculate Growth”, the tool will generate results based on WHO’s growth data for a 12-month-old male child. The Z-scores will indicate whether the child’s weight, height, and weight-to-height ratio are within the normal range.
Key Features and Benefits of the WHO Growth Chart Calculator

- Easy to Use: With a clean interface, it’s quick and simple to input data and obtain results.
- Instant Results: Within seconds, the tool calculates and displays three crucial Z-scores to assess the child’s growth.
- Comprehensive Metrics: The calculator evaluates three essential growth metrics—weight-for-age, height-for-age, and weight-for-height—to give a full picture of a child’s growth.
- Shareable Results: Share results easily with doctors, family members, or other caregivers using the built-in share feature.
Tips for Using the WHO Growth Chart Calculator
- Accuracy is Key: Double-check the child’s height, weight, and age before entering the data to ensure the results are as accurate as possible.
- Use Regularly: Track your child’s growth periodically to ensure consistent development. The WHO Growth Chart Calculator can be a valuable tool for monitoring progress.
- Consult a Pediatrician: While this tool is helpful, it’s always best to consult with a pediatrician if you have concerns about your child’s growth. They can provide additional insight based on medical expertise.
- Interpret Results with Caution: Z-scores are helpful, but they are just one part of the growth picture. A negative Z-score doesn’t necessarily mean there is a serious health issue. Consult with a doctor if the scores are outside the typical range.
