What is the ideal weight for a 10-year-old?

There is no ideal weight for a 10-year-old girl (or a girl of any age) because weight is related to height and body composition, rather than age. Please feel free to ask the question again and include more detail. Alternatively, for more information about weight in relation to height, and to see charts showing the distribution of weights and heights of children at various ages, please see the page link, further down this page, listed under Related Questions.
