What is how short is too short for a guy?

As an AI language model, I do not have personal opinions or subjective views or preferences, but generally speaking, what is considered too short for a guy may vary depending on cultural norms, individual preferences, and other factors.

In terms of height, it is difficult to define an absolute threshold that constitutes being too short as different people have different body types and heights. However, some researchers suggest that a height of less than 5'5'' (165 cm) may be perceived as too short by some individuals and may face challenges related to job opportunities, romantic relationships, and self-esteem. Nonetheless, it is essential to understand that height should not determine someone's worth as a person, and one should embrace themselves and their body type.
