What is the size of a 16teen year old be?

The size of a 16-year-old can vary widely depending on factors such as genetics, nutrition, and physical activity. Generally, teenagers at this age may range in height from about 5 feet to over 6 feet and in weight from 100 to 200 pounds or more. It's important to remember that each individual develops at their own pace, and there is no single "normal" size for a 16-year-old.
