You know another thing that is always odd? There are so many variations on how to measure the wrist too - weird.
Anyway, I found this:

basically just reconfirms I'm a large framed person - ankle is 9" (first thing in the morning when I have zero puffiness) and my thumb and forefinger don't touch - not even close - like an inch to go! Actual measurement is 6.66. Elbow girth test is really hard to do by oneself, but with that I get right at large frame, 2 2/3s (I think). All for my height of course.
But more, you can tell by looking at someone, can't you? (when they are close to their ideal weight especially). I can see in people's avatars even by their face alone sometimes what their frame size is. I volunteer at my son's 1st grade class every day and the differences in sizes with these 6/7 year olds is HUGE. Not just in height, but in every way. Girls and boys with teeny tiny butts/hips and then kids with big, solid frames. It's the same in my fitness classes - you can SEE frame size so easily -without measuring.
