Directions: Completely fill in the form below. When measuring the circumference of your waist, it is essential that you take the measurement at your belly button. The size of your pants is not a waist measurement and may skew the accuracy of your calculation. It's best to use a tape measure. However, a regular ruler, a piece of string, and some basic math skills will be adequate. If you lack a piece of string, be creative!
