How big should you be at 15?

At 15, growth and size can vary significantly based on genetics, gender, and individual development. On average, boys may range from 5'5" to 6'0" and girls from 5'0" to 5'7", but these are just general guidelines. It's essential to focus on overall health and well-being rather than specific height or weight metrics. If there are concerns about growth, consulting a healthcare professional is advisable.
