What is a normal weight for a child or teenager of a certain height and age?
There is no perfect or ideal weight for a child because weight
is related to height and body composition, rather than just age
alone. The weight of a child or teenager (relative to their
peers) can vary during growth and the growth charts can only give a
general idea of a child or teenager's weight and height at a given
age in relation to their peers. Use the growth charts, further down
this page, listed under Related Links, to see the distribution of
weights and heights of children and teenagers at various stages.
So, is your child or teenager overweight? It is possible to get
an estimate of whether or not a child's growth is appropriate by
consulting the charts. If there is a large discrepancy between
height and weight percentiles, it suggests that a child's weight is
disproportional to his height. If so, it is possible that a child
will be overweight. (Consult a doctor, for a professional
evaluation, if you think your child is overweight before starting
any sort of calorie restriction.)
An example: 12-year-old Billy is 58 inches in height and 130
pounds in weight. Is there reason to be concerned?
Consulting the growth charts, we see that 58 inches for a
12-year-old is just about at the 50th percentile. In addition, at
130 pounds and 12 years old, Billy is at the 95th percentile for
weight. Therefore, while Billy is taller than only 50% of children
his age (he's of average height), he is heavier than 95% of them!
That is a large discrepancy and, therefore, probably something to
discuss with a medical practitioner.
Another example: 8-year-old Michael Jordan Jr. is 55 inches in
height and 72 pounds in weight. Is there reason to be
Look at the growth charts. 55 inches is extremely tall for an
8-year-old, above the 95th percentile. For weight, 72 pounds is
right around the 95th percentile. So, while lil' Mikey is taller
than most children in his age group he is also heavier than most
children in his age group - he is proportional, suggesting that
things are normal.
