Kids Height & Weight Percentile Calculator

Growth percentiles indicate how your child's height or weight compares to other children of the same age and sex. For example, if your child is at the 75th percentile for height, they are taller than 75% of children their age. Percentiles between the 5th and 95th are generally considered within the normal range.

The WHO (World Health Organization) growth standards describe the expected growth of healthy children under optimal conditions. They are based on data from children in six countries who were breastfed and raised in environments that promote healthy growth. These standards are used worldwide as a reference for assessing child growth and development.

Consult your pediatrician if your child's measurements consistently fall below the 3rd percentile or above the 97th percentile, if there is a sudden change in growth percentile (crossing two or more percentile lines), or if height and weight percentiles are significantly different from each other. A single measurement is less important than the overall growth trend over time.

Growth spurts are periods of rapid growth that are normal in childhood. Infants grow rapidly in the first year, and children often experience a growth spurt just before puberty (around ages 8-13 for girls and 10-15 for boys). During growth spurts, children may temporarily shift percentile lines before stabilizing.

Yes, BMI for children is interpreted using age- and sex-specific percentiles rather than fixed cutoffs used for adults. A child's BMI percentile compares them to other children of the same age and sex. Underweight is below the 5th percentile, healthy weight is 5th to 84th, overweight is 85th to 94th, and obese is at or above the 95th percentile.
