Where can you find a weight chart for boys?

The World Health Organization and the Centers for Disease Control and Prevention offer percentile weight charts for boys on their websites. As of March 2015, the CDC recommends that WHO growth charts be used from birth to age 2 and CDC charts be used for children age two and older.

In the United States, pediatric growth charts have been used by health-care providers and parents to track children's growth since 1977. However, it's important to remember that growth charts should be used in conjunction with other diagnostic tools instead of being the sole measure for determining a boy's health, according to the CDC.
