This is a great question. Although the FDA issues standard guidelines for breast augmentation at age 18, actual breast development is very variable from woman to woman. I explain more in the video.

At What Age Do Your Breast Stop Developing?

Approximately between the ages 16-21-- when puberty ends. Although, there are cases of significant increase in breast size in a mid 20s or later. There does not appear to be a clearly identifiable time when breast growth absolutely stops. Generally speaking, by the time a woman is 21yo-- she can count on that being her final size.

Breast growth and age

No one knows for sure.  We think breasts stop growing (developing)  between 16 and 20 with the commonly held assumption that if they haven't changed for an extended period of time (1-2 years and bra size is the same), then growth is complete.  Of course, they change with other factors- weight gain, weight loss, pregnancy, hormones etc.  

Breast Growth is quite variable!

The time growth stops is a broad range - roughly 16-20 years old - but regardless, the final meter is when your breast size has been stable for approximately 1 year.

In addition, breast growth is normally asymmetric - you may notice one grows faster or larger than the other. Most adults, in fact, have asymmetric breasts - it is just a question of degree. They can be asymmetric with respect to their size, as well as the position of the nipple/areola.

Hope this is informative!

Breast Development

Breast growth and development varies markedly from patient to patient but typically reaches full maturity between the ages of 16 to 20 years. It is important to consider, however, that breasts will continue to undergo size and shape changes throughout life due to weight fluctuation, the impact of pregnancies, hormonal changes, and aging.

In general most women will reach full breast maturity between 18-20 years of age however the breasts continue to change over a woman's entire life. In addition to age and gravity, things like pregnancy, breastfeeding and menopause will cause changes in the breasts as well.

Breast development usually occurs through the teenaged years, and physiologic development ends usually by 18 years of age. Thereafter, breasts continue to evolve and change, and this is affected by weight loss or gain, pregnancy, and aging overall.

Hi
Normally women stop beast development between 16 and 18 y.o. but they have changes in size and consistency in pregnancy, and throughout life.

Every Woman Is Different

Thanks for your question. As with many things related to the body, there are few absolutes when it comes to breast development. Typically, the breasts stop growing after puberty ends, which can vary but often occurs between the ages of 15 and 18. Of course, just because puberty is over doesn't mean the breasts will never change again. Weight gain or loss, hormonal fluctuations, and pregnancy can all affect the size and the shape of the breasts over the course of a woman's life. So although the breasts may stop growing, they continue changing throughout a lifetime.

Breast continue to change throughout your lifetime. Breast development usually stops shortly after puberty, between age 16-20. However, breast development is also related to your weight gain and loss and your pregnancy history. Later in life breast change is associated with hormone deficiencies cause breasts to change in a way usually associated with atrophy and sagging. 
All the Best,
