how big would my breasts be if i was a woman

Breast size if someone were a woman depends on multiple factors including genetics, body weight (fat composition), hormones, age, and life stages such as puberty and pregnancy. Breast size is generally proportionate to body frame, height, and weight, and can change over time due to these factors. It is not predetermined but influenced by a combination of biological and environmental variables, including genetics, weight fluctuations, hormonal changes (like estrogen, progesterone, prolactin), and pregnancy. To estimate breast size more specifically for an individual, measurements like bust circumference and band/frame size are needed, as breast cup size is calculated by the difference between bust and band size. In summary, the exact breast size if someone were a woman cannot be determined without personal measurements and knowledge of these influencing factors, but it will likely be related to body proportions and biological factors such as genetics and weight.
