Tag: Large hands

Acromegaly, a rare hormonal disorder affecting adults, can cause a gradual and noticeable increase in hand size due to excess growth hormone. While this is a medical cause, the truth is that a person's hand size is most often determined by genetics. A person's hand size may change due to various factors, prompting the question: What causes bigger hands?

According to research from the *International Journal of Industrial Ergonomics*, the average hand length for an adult male is about 7.6 inches (19.3 cm), while for an adult female it is around 6.8 inches (17.2 cm). The determination of **what is considered large hand size** is often relative to these population-based averages, varying significantly between individuals and across genders.

According to the National Institutes of Health, acromegaly, a rare hormonal disorder, is one potential cause of big hands, and often begins with subtle changes that go unnoticed for years. Understanding what is the cause of big hands requires looking beyond genetics to potential underlying health conditions.
