Ok so, weight charts and BMI charts have ranges based on the size of your frame. So how do you know what the size of your frame is? I mean, I assume I would know it if I were big boned, right? So I guess I'm not. But how would I know if my frame is small or medium? How'm I going to know if I've got little teeny bones? The fat covers everything up!

Someone once told me that you can tell the size of your frame by wrapping your fingers around your wrist and seeing if your thumb and pinky touch. I think that may be BS though. Is there some scientific way to figure it out, eg the circumference of your skull multiplied by the square of the hypotenuse? Or something?

I didnt measure my wrist, but I am 4'11 and def. small frame

Hi, this is my first post. I think the wrist measurement might be okay if you are at a good weight for you - when I was at a 'normal' weight I could overlap my finger and thumb. Now that I am 100+ overweight they don't even meet. So I know your wrists gain weight too!! I am 5' 2 1/2" and by my wrist measurement I would be considered a medium frame. However, my orthopedic surgeon who did my knee surgery said I had the "tiniest bones for such a big person" he had ever seen. Also my dentist has to use a child's mouthplate (or whatever it is) when taking impressions for a crown, so I think I am probably small framed.
