What is the ideal weight for a 15 year old?

There is no 'ideal' weight for a 15-year-old boy or a person of any age. Weight is related to height and body composition rather than age. However, growth charts can give a general idea of a child's weight and height in relation to their peers. Please use the related page link, further down this page, listed under Related Questions, for further information and to see the distribution of weights and heights of children at various ages. Alternatively, please feel free to ask the question again and include more detail.
