When taking your measurements, use a cloth tape measure, not a metal one, and make sure that when you circle your chest, waist, or hips, the tape is level and not too tight or too loose. Measure yourself against your bare skin, not over clothes, and be sure to record your measurements.

Use a measuring tape to measure horizontally around your head approximately one inch above your eyebrows, and from the point on the back of your head that gives the largest possible number.

Use a measuring tape to find the circumference of your thigh at its widest point. Measure both thighs and take the biggest number.
