Child Growth Tracker

Keep height, weight, BMI, and age in one place so growth feels easier to follow over time. Add each new measurement, review the pattern, and see a cleaner summary of what is changing from one check-in to the next.

This tool is built to help families stay organised, not replace a doctor’s interpretation. Growth charts are one part of a bigger picture, and children should be assessed in context rather than by a number alone.

Track over time Save repeated measurements directly in the page and review the trend at a glance.
See BMI clearly Each entry calculates BMI automatically from the child’s height and weight.
Use an official reference For ages 2–19, the page includes the official CDC child and teen BMI calculator.

Height trend

Measured values over time. This is a tracker view, not a percentile chart.

Weight trend

Measured values over time. Use consistent measuring methods for cleaner comparisons.

How to use this tracker well

Try to measure in similar conditions each time and focus on patterns over multiple entries rather than reacting to one isolated number.

When to bring growth up with a doctor

If growth appears to flatten unexpectedly, jumps sharply, or seems out of line with what you usually see, bring your notes and measurements to your child’s doctor for proper review.

Saved measurements

Official BMI reference

CDC child and teen BMI calculator

For children and teens ages 2 through 19, CDC interprets BMI using sex-specific BMI-for-age percentiles. Use the official calculator below when you want that reference point alongside the tracking tool above.

Helpful guidance

Use growth numbers with context

Growth charts and BMI are screening and monitoring tools. They help show where a child sits compared with a reference population, but they are not meant to be used alone as a diagnosis.
