Pre-school age is so important for a child’s development. It’s a time in which powerful habits can be formed, but it’s important to remember that each child is an individual and will develop in different ways and at a different rate.

Pre-schooler growth tool

The average pre-schooler will gain around four pounds (1.8kg) and grow about three inches (7.6cm) per year, between the ages of two and five. Of course, there’s no such thing as average when it comes to children, who tend to grow at different rates!

If you would like to chart your pre-schooler’s growth, and are curious as to where they sit compared to other children their age, a child growth chart can be a useful tool. Do keep in mind, however, that using a weight calculator for kids shouldn’t replace their usual health checks, which will calculate the ideal weight for kids as individuals. If you do find that you have any concerns when charting your pre-schooler’s weight, you should talk to your doctor.

Child weight chart

A percentile scale is used to chart growth in young children, allowing parents and health professionals to see where the child’s growth rate lies in comparison to the average pre-schooler. This chart uses the percentile scale method to track your child’s weight vs. age percentile. This will enable you to see how much and how quickly they are growing between the ages of two and five years old.

How to use this tool:

This easy to use weight chart for kids provides your pre-schooler’s weight percentile based on their age and weight. Known as a child age-weight chart, it uses data from the World Health Organization (WHO) for its calculations.

Note that the normal weights for kids will vary depending on gender, so there is a difference between the weight chart for boys and the weight chart for girls.

To use the tool, simply enter your child’s gender, date-of-birth and weight. The average weight percentile is 50%, so any lower value means your child weighs less than the average baby their age. A value greater than 50% means a child’s weight is above his peers.


This tool is for reference purposes only. The result does not necessarily mean your child is overweight or underweight and it is not a substitute for having a health care provider monitor your child’s growth at regularly scheduled exams. At these visits, your health care provider will determine whether your child is following a healthy growth pattern over time.
