Percentile Chart and Calculator

Health Care  Pediatrician  Pediatrics

Description:
This calculator provides your child's weight percentile
based on stature. Stature is upright height or standing
straight height. The percentile shows how your child's weight
compares to other children of the same height. 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 children.
A percentile of 50% represents the average or mean weight.
A value below 50 percent means a child weighs less than
the average. A value greater than 50 percent means a child
is above average. This does not mean your child is overweight
or underweight. A doctor or physician should be consulted
to determine weight status.
