No, I turned 13 6 months ago, and when I did, I was 5 foot 11. I went to a doctor thinking that there might be a growing thing that made me really tall, but he said that it was just natural for me, because (I am adopted btw) My birth mom, was about 6 foot 4. 5'4 is the regular length for your age! I am now 6'2, and the tallest kid in my school. Don't worry about being too tall, because you are the perfect length!
