Breath out normally. Run the tape measure down the center of your body to the waistline and you have your measurement. The waistline is the midway point between the top of your hips and the bottom of the rib cage. Find a chest protector closest to your size for ultimate comfort and protection. Chest protectors come in three general sizes -- adult, intermediate and youth. Adult protectors usually measure 17 inches, while intermediate and youth sizes generally measure 16 and 15 inches, respectively, but different sizes exist.
