5'2, 104lbs, 18, what is considered a normal breast size for a girl of my age and weight?

There is no single “normal” breast size for someone who is 5'2", 104 pounds, and 18 years old. Breast size is influenced mostly by genetics, body fat distribution, hormones, and natural breast development, so two people with the same height and weight can have very different breast sizes and both can be completely normal.

At 18, breast development is often close to mature, but some changes can still happen with weight fluctuation, hormonal changes, pregnancy, or aging. Cup size is also an imperfect measurement because it changes with band size and bra brand, so it is not a reliable way to judge health or whether your breasts are normal.

If your breasts are very asymmetric, painful, changing rapidly, associated with nipple discharge, or causing major distress, it is reasonable to speak with a primary care doctor, gynecologist, or board-certified plastic surgeon for an exam. Otherwise, small, medium, or large breasts can all be normal for your age and body type.

There is no normal breast size, but there are tissue-based measurements and 3D simulation software that can help you understand the implant selection process.

There is no "normal" breast size for any age, height, or weight. A better question would be what your goal breast size is. You are only 18, so there is no rush to go into anything, but if your goal is to have larger breasts than you currently have, a breast augmentation may help get you there! One thing to remember is that silicone implants are only FDA approved for those 22 years old and up, so a breast augmentation for you right now would likely be with saline implants (though that is a discussion to have with your surgeon)

You cannot standardize a breast size by age and weight, it will depend on many factors, measurements of the frame of the chest, breast tissue that must be filled, shape of the breasts of each patient, etc. there are many factors, you must go to a consultation, so that they explain to you, see sizes, use testers and decide with your surgeon what is your best option

Dear Oil Fox,
there is no range of normal size of breasts. Every individual has a different breast size and shape and there is a great variety. In case of any breast issues, a lot can be improved with surgical and non-surgical procedures.

Thanks for your question. Unfortunately, there is no "normal" breast size. Every woman is completely different. If you have concerns about your breast shape or size (too big OR too small), there are resources and surgeons you can seek out. Good luck!

There is no "normal" size but for someone of your height and weight an average size would be a "B" cup. Generally, women develop breast tissue until about age 22.

If interested, I recommend an in person consultation with a plastic surgeon to discuss your goals and be measured. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what is right for them.

Thank you for your question. Breast size is variable and there is no such thing as “normal” when it comes to breast size in a woman. If you feel good about your body, and are pleased with your breast size, then all is good. If you feel you are too large, this can result in neck, back, and shoulder pain and a breast reduction surgery can help restore a more proportionate breast size. If you feel you are too small then a breast augmentation can be considered.

Many women live their lives either smaller or bigger than they might have wished, without ever having surgery. If your quality of life is not significantly affected by your current breast size, no need to do anything. If you have concerns, please seek out a board certified plastic surgeon who can advise you. Best of luck.

There is not a standard for breast size given a person's height and weight. If you are unhappy with your breast size I encourage you to visit with a board certified plastic surgeon near you to discuss your options. If you feel your breasts are too large you can consider a reduction. If you would like more volume, you may be a candidate for an augmentation.
