The mismatch percentage for seat width dimension was more
than twice as large for girls (73.7%) as for boys (35.7%) (Fig. 3b). It is
apparent from Table 4 that, for the majority of girls (72.9%) and for
nearly one third of boys (29.7%), seat width dimension was smaller
(low mismatch) than the mentioned functional criteria. It was also
shown that the mismatch percentage increased with grade level for
girls (from 54.0% in Grade 9 to 86.3% in Grade 12). For boys, the
Grade 10 (19.4%) and Grade 12 (47.5%) students had the lowest and
highest mismatch percentages, respectively.
