The measurements need to be accurate to within 0.5cm or 0.25 inches(centimeters tend to produce the most accurate results) and should be taken as follows:
- Height: taken without shoes
- Neck: taken below the larynx sloping slightly downward at the front
- Waist: for men at navel height, for women at the smallest point
- Hips: (women only) at the largest point.
