(A) Measurement of length using a length stadiometer. This is the preferred method for measuring stature in a child less than 2 years old. For an accurate measurement, the child must be held fully supine, with knees fully extended, as shown.
(B) Measurement of length using a tape measure. This should be done on a firm, flat surface, such as the examining table. With the child held gently in the proper position, make marks on the surface to indicate the position of the head and heels, then remove the child from the table and measure the distance between the marks. A similar technique may be used for older individuals who are unable to stand, recognizing that recumbent length (when optimally measured) is generally slightly more than standing height.
