I found a BMI calculator that might help more. Keep in mind that if girls in your school and on your social media pages are promoting being thin and acting like anorexia is the "in" thing and are pressuring you that this is a horrible idea and will have profound consequences on their lives as well as anyone they manage to influence. Anorexia is a mental illness. Being thin as a stick is not healthy. Eating healthy and getting just the right balance in exercise and rest is so much better for you.
It's alright to just try to be healthy, though. Still, keep in mind that the BMI calculator that I found is only a tool and that your body is still growing and maturing:

This is a touchy one because I don't like BMI charts. They do not take many factors into account thereby making them a reliable tool. For example, your bones structure, (i.e. thin build or stocky), Body fat/muscle ratio, etc. If Arnold Schwarzenegger was to use a BMI (weight vs height) chart while bodybuilding, it would have classified him as obese. Another way to look at fat versus muscles is that a cubic inch of muscle will weigh more than a cubic inch of fat. Muscle is about 18 percent more dense than fat. So a better question is am I in shape or do i need to convert more areas of fat to muscle? With that said, here is a weight chart that should only be used to give you an idea, so don't take it as gospel.
