I am 14 and weight 97 and am about 5"2
But I measured my waist line and it is 26!
I want to know what the average waist line is for 14 year old girl!

Using this as referance for you...
Body-Mass Index, Waist-to-Height Ratio and More...

You seem to be fine in my opinion. (fyi it will say you may be at risk for being underweight, disreguard this, as that is because you are 14 and not 18 or older. :) so don't freak out)

Thank you so much.

No problem hon.
On a side note. Try not to be SO concerned with your BODY. Focus on YOU. OK :) be the best you that you can be. Don't be concerned about size, looks, etc. :)

At 14 your body is growing and changing, adolescent girls should have a bit of a tummy, due to puberty and periods. You have absolutely nothing to worry about. Eat well and healthyly and enjoy your life. You've got a lot ahead of you with exams etc so work hard, have fun and be confident. Love yourself and people will notice what a great girl you are!
