I was thinking how weird it is that so many of us are relatively the same height and weight, but we all look so different. I figure it has to do with our frame size. So, are you small framed, medium framed, or large framed? The quickest way to test this is to wrap your thumb and your middle finger around your wrist, right below your hand. If your fingers overlap, you are small framed. If your fingers touch, you are medium framed. If you have space between the two, you are large framed.
If you are the type of person who needs actual measurements and a calculator, here you go:
You can measure on that website by wrist or by elbow, or both.
I have a big overlap, I'm small framed.
