Research shows that 57% of top executives in the UK’s FTSE 100 and leading multinational firms are over 6ft tall. This correlation suggests that height influences not only how others perceive an individual, but also how they perceive themselves. Being taller naturally fosters greater self-confidence, a stronger sense of authority, and enhanced leadership abilities, creating a lasting psychological advantage.

Studies on ‘power posing’ (Carney et al., 2010) found that simply adopting an upright posture could lead to a 16-19% increase in testosterone levels. This hormonal shift is triggered by the posture itself, which sends signals to the brain that reinforce confidence and authority. Standing tall is not just about appearance, it also shapes how you feel and how assertive you become.

According to a study by Deaton and Arora (2009), men over 5'10" (1.78m) have a 2.2% higher life satisfaction score on the Cantril scale. This difference is linked to the association between height, self-confidence, authority, and perceived social status. Being taller not only influences how a person is perceived by others but also how they perceive themselves. By feeling more confident and more legitimate in social interactions, they experience a greater sense of well-being, ultimately leading to higher life satisfaction.
