Measurements of sitting-height are important in studies of human growth, development and population differences. They allow the calculation of subischial leg length (stature less sitting height) and comparisons between these two measurements make investigation of proportionality possible. In addition, if the subject has deformities of the legs or feet which prevent standing, sitting height is the most significant growth variable. The anthropometer commonly employed for measuring sitting-height (Weiner and Lourie 1969, Cameron 1978, Cameron, Hiernaux, Jarman, Marshall, Tanner and Whitehouse 1981), is extremely difficult to use accurately. The problem is that one hand must be used to maintain the anthropometer vertically against the spine of the subject, who is sitting on a table, and the other hand is used to maintain the head position or do this and apply pressure if a 'pressure technique' is being used (Cameron 1978). It is common for the anthropometer base to tilt out of vertical or the arm of the anthropometer to slide off the crown of the head. The observer, standing along side the subject, needs considerable experience to ensure that the blade rests on the crown of the head, the subject is in the correct position, the anthropometer is vertical and the correct pressure is applied. Many field workers, who measure after short training sessions, express considerable doubt about the reliability of their sitting height measurements when an anthropometer is used. The alternative, of purchasing a sitting height table, is costly (about £300). This note describes a sitting height table, constructed by a carpenter from easily obtainable materials, that can be used with children and adults of all ages to measure sitting-height with as much ease as the regular sitting-height table; it can also be used to store other instruments when not in use. Figure 1 illustrates the sitting height table and figure 2 gives its dimensions. It was designed to fit over the base of a Harpenden Portable Stadiometer but with suitable modification could be used with almost any type of stadiometer. It is composed of a box made from 15 mm plywood with formica covering the top. The footboard is also of 15mm plywood and formica, attached to the box using shelf fixing-brackets which allow the footboard to be moved from a position 20 cm below the surface of the table downwards in 3 cm steps. The depth of the box has been kept small (30 cm) because in theory only the ischial tuberosities and upper thighs need to be in contact with its surface. The knees should be very slightly raised so that the upper line of the thigh is horizontal. The footboard position is adjusted to maintain the thigh position and the feet moved forward or back to ensure right angles at the knees and ankles. When in use the box is placed against the vertical backboard of the stadiometer and fixed in place, to prevent rocking, by a small latch at the back of the box. The subject sits on the box in the usual position for sitting height with head, back and legs properly positioned. The
