What it means
In kilograms, the usual range for a 19-year-old is 54.8 to 94.1 kg for boys and 46.0 to 82.0 kg for girls (5th to 95th percentile).

Two growth charts. For children under 2, we use World Health Organization growth charts. From age 2, we use CDC growth charts. US doctors follow the same switch.
What's a usual range? Most healthy children are between the 5th and 95th percentiles. Many healthy children are above or below that range. Doctors look at the trend over time, not one weight.
Percentiles aren't grades. The 50th percentile is the middle: half of children weigh more and half weigh less. It isn't a target weight.
How to measure your child
- Weigh your child in light clothing, without shoes.
- Write down the weight to one decimal place, in pounds or kilograms.
- Use the same scale at the same time of day when you compare.

Common questions
Short answers about how these calculators work.
Why do some ages use WHO charts and others CDC charts? In the US, doctors use World Health Organization growth charts from birth to 2 years and CDC growth charts from age 2. We follow the same switch.
Is a child above the 95th percentile unhealthy? Not from one number. A percentile shows where a child falls compared with others the same age. Your child's doctor looks at it along with height, growth over time and a checkup.
