How long does it typically take for the changes of puberty to complete?

Puberty is a significant developmental stage characterized by the physical, hormonal, and psychological changes that occur as a person transitions from childhood to adulthood. It typically lasts three to four years, during which individuals experience various changes, including the development of secondary sexual characteristics, growth spurts, and changes in body composition.

Such transformations do not happen overnight and vary from person to person, with some beginning puberty earlier and others later. The entire sequence of hormonal changes and the resultant physical developments usually take this three to four-year timeframe to complete. Thus, selecting a duration of three to four years is accurate when considering the average duration of the entire pubertal process.
