Bones are generally considered fully developed around the age of 25. This is when the process of bone ossification, or osteogenesis, is usually complete.
Bone development is a complex process that starts during embryonic development and continues through adolescence and into early adulthood. This process involves the replacement of cartilage with bone tissue and the lengthening and thickening of bones. While most bones reach their adult size and shape during adolescence, the final stages of bone maturation, including the complete fusion of growth plates, typically occur around age 25. Individual variation exists, meaning some people might reach full bone development slightly earlier or later than this average.
