In and sales positions, the relationship between height and salary was closely related. Yet height also mattered in less social occupations such as accounting, programming, engineering and clerical work.

Judge also found that height was more important than gender in predicting income. Taller women get paid more than their shorter counterparts. The tall began their careers with bigger paychecks, and kept the fiscal advantage into their 40s and beyond.
