Many of the current techniques for body and weight analysis such as the standard Body mass index do not take into account the different body frame sizes of people.
One easy way to determine your body frame size is to wrap your thumb and major fingers around the smallest part of your wrist.
- If the fingers overlap you are a small frame.
- If your fingers just about touch your are a medium frame.
- If your fingers don't touch you are a large frame.
Add 10 percent for a large frame size, and subtract 10 percent for a small frame size to the ideal weight calculator.
If you want a more exact measure to calculate your body frame size use either your wrist circumference or elbow breadth (see below for a description to measure elbow breadth).
