Waist: Measure the circumference of the waist at a horizontal level around the navel for men and at the level with the smallest width for women. Do not pull the stomach inwards to obtain accurate measurements.

Neck: Measure the circumference of the neck starting below the larynx, with the tape sloping downward to the front. Avoid flaring the neck outwards.

For women only: Measure the circumference of the hips at the largest horizontal measure.
