Instructions

Part I

~ Take your measurements: The form will instruct you to input circumference measurements (in inches), of your abdomen and hip areas. Use a cloth tape measure and be sure to write down each measurement.

~ Measure your abdomen: Remove or lift clothing. Stand up straight, yet relaxed. Wrap the tape measure around your mid-section at the level of your navel. Pull the tape just tight enough to take up the slack. Do NOT suck in your stomach.

~ Measure your iliac crest: Stand and find where your upper pelvic bones protrude the most (you can feel for them on either side of your waist). Measure the circumference at this point.

~ Measure your hips: Stand and find the area of your body below your navel where you are the widest. This area can vary greatly from person to person. Wrap the tape measure around your body right there.
