The percentile shows how your child's weight compares to other children. The percentile tells you what percentage of children weigh less than your child. For example out of a sample of 100 children, a percentile value of 40 percent means your child weighs more than 40 children and weighs less than the other 60.

For adults 20 years old and older, use the Adult BMI Calculator.
Your BMI, height, and weight percentiles show how you compare to everyone else. For example, if you are 50th percentile in height, that means that you are taller than 50 out of 100 typical kids your age and sex, or actually kids who live in the 1970's and 1980's before the childhood obesity epidemic started.
A percentile shows the relative position of the child's BMI, Weight, or Height among children of the same sex and age. For example, a boy at the 25th percentile for weight weighs more than 25% of boys his age. If a girl is at the 40th percentile for weight, she weighs more than 40% of girls at that same age.
At the extremes (> 97th percentile or < 3rd percentile), small differences in percentiles represent clinically important differences in height. At these extremes, the z-score is a more precise reflection of how far the measurement deviates from the mean, and is a useful tool for tracking changes.
Measurements such as height, weight, and head circumference of a child can be compared to the expected values based on data from these growth charts of children of the same age and sex. In general, children maintain a fairly constant growth curve, which is why these charts can be used to predict the adult height of a child to a certain extent.
