Ensure that the subject does not pull their stomach inwards to obtain accurate measurements. 2 Measure the circumference of the subject's neck starting below the larynx, with the tape sloping downward to the front. The subject should avoid flaring their neck outwards. 3 For women only: Measure the circumference of the subject's hips at the largest horizontal measure.
