🔒 Everything runs 100% in your browser. Your files and input are never uploaded to any server.
Enter your child's gender, age in months, height, and weight to instantly see how they compare to the 50th percentile (average) of the 2017 KDCA standard growth chart. All calculations run entirely in your browser, so no child data is ever sent to a server, making it a quick reference for tracking growth trends at home.
How to use
- Select your child's gender (boy/girl).
- Enter their age in months (0-72).
- Enter their height (cm) and weight (kg).
- View the height/weight ratio versus peer averages along with an undergrowth/normal/overgrowth indicator.
FAQ
- Can this replace a doctor's growth assessment?
- No. This tool is a simplified simulation comparing your child's measurements to average values from the 2017 growth chart; consult a pediatrician for an accurate developmental evaluation.
- Is my child's data stored or sent anywhere?
- No, every calculation happens locally in your browser and nothing is transmitted or saved.
- Does this work for children older than 72 months (6 years)?
- The tool only covers the 0-72 month range, so results for older children won't be accurate.
