Here's a quick estimate you can do right now. Wrap your thumb & middle finger around your opposite wrist at the smallest point.

   * If your middle finger & thumb overlap, you have a SMALL frame
   * If your middle finger & thumb meet, you have a MEDIUM frame
   * If your middle finger & thumb don't meet, you have a LARGE frame

Want something more concrete? Grab a tape measure and use the following chart to determine whether you're small, medium, or large boned. Or, use a professional caliper.
