What is the average weight or a 5,6 16 year old?

I am 16 years old and am about to turn 17 and i am a girl. I weigh about 142/143. I am athletic and i have a lot of muscle.. a little too much in my opinion but it doesn't matter. I think i am a medium build maybe on the larger side of the mediums. I feel like i have every wide/large bones. for example i have a little "chub" on my stomach but you can still see were my rib bones end because they stick out. anyways i just wanted to know the average or healthy weight. i looked online but different websites said different things. Thanks so much for the help
