How do you know what cup size you will be by the ccs?

Thank you for the question.  

There is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved. For example, I do not think that generalizations of "200 cc equates to 1 cup" hold any validity or are helpful in any specific way. 

Generally speaking, the best online advice I can give to ladies who are considering  breast augmentation surgery ( regarding breast implant size/profile selection) is:

1. Concentrate on choosing your plastic surgeon carefully.  Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. ***Ask to see lots of examples of his/her work.

2. Have a full discussion and communication regarding your desired goals  with your plastic surgeon. This communication will be critical in determining  breast implant size/type/profile will most likely help achieve your goals. 

In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, I have found that the use of words such as  “natural” or "C or D cup” to "too big on me" etc means different things to different people and therefore prove unhelpful.

 Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup  size may also be inaccurate.  Again, the use of computer imaging has been very helpful during the communication process, in our practice.

3.  Once you feel you have communicated your goals clearly,  allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals.  Again, in my practice, this decision is usually made during surgery,  after the use of temporary intraoperative sizers.

I hope this (and the attached link, dedicated to breast  augmentation surgery concerns) helps. Best wishes. 

Implant size vs. Cup size

Thank you for your question.

Please know that it is a common misconception that implant size (ccs) correlates with the bra cup size. A bra-cup size itself requires many measurements to describe it.

Bra sizes vary among manufacturers, and they can label the cup size by any designation they choose. So a C will be a D for another. Additional factors, such as demi and full cup coverage, specific fabrics, padding, and elastics, can all affect the fit of a bra.

If we consider all things being equal – i.e., you get a bra from the same manufacturer and of the same style - then I think you might find it helpful to know that a study by Dr. Bengtson and Dr. Glicksman titled “Standardization of Bra Cup Measurements” has shown that the average implant volume required to increase the cup-size by 1 size is equal to 205 ccs. It was also found that normally breast augmentation increases the cup size by 2. However, it is also important to consider the profile as even a smaller implant with a high profile can increase cup-sizes by the same amount compared to a large implant with low profile.

Now, it may be helpful to do bra-sizing trials with the bra of your choice when you go in for a pre-operative consultation with your board-certified plastic surgeon. Now, although you give importance to cup size designation, what should matter most is that the implant looks good aesthetically and that the chosen bra fits and feels comfortable.

Note that board-certified plastic surgeons will assist you in choosing an implant that is more tailored to your breast characteristics in order to provide natural looking breasts.

The implant has to fit YOUR body dimensions. The more you deviate from the proper fit, the more fake your breasts will look.

Surgeons use what is called tissue-based planning. The planning takes into account the effects of implants on tissues over time, risks of excessive stretch, excessive thinning, visible or palpable implant edges, visible traction rippling, ptosis (Sagging), and breast tissue wasting.

To determine the implant size, breast measurements must be made: 1) Base Width of the existing breast tissue, 2) breast skin stretch, and 3) Nipple-to-Inframammary Fold distance. The combination of these measurements will help determine tissue coverage and the required implant volume to optimally fill the breasts.

So please focus more on having full and natural looking breasts rather than trying to fit into a particular bra-cup size.  

All this being said, if you trust your surgeon and their judgment and the decision-making method used to choose the implant size, then you should be in good hands. Make sure to fully and comprehensively share your desires, expectations, and concerns to avoid miscommunication and post-operative concerns/regrets.

Hope this helps

What Cup Size with # of CCs

Thank you for your question! Depending on your natural breasts, the cup size will vary from patient to patient. For example, if someone starting with a B cup gets 300ccs, they may end up with a C or D cup. If someone else starts off as an A cup and gets 300ccs they may end up with a B or C cup. Regards,

I appreciate your question.

It depends on your chest wall measurements and existing breast tissue as implant size does not accurately correlate to a bra size.  It also depends on the brand and style of bra you wear as size varies from manufacturer to manufacturer.

The best way to assess and give true advice would be an in-person exam.

Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery.

Best of luck!

How many ccs are in a cup size?

You don't and a board certified plastic surgeon can help you achieve your goals especially if they have experience.   I think it's a myth that ccs equate to cup size as there are so many other factors that have to be considered.   Good luck and great question!

Bra Sizing and Breast Implant Volumes


Please listen carefully.  There is no way to equate implant volume to bra sizes. That is ok though, because talking about your aesthetic goals using cup sizes, although common, leads to frustration and unhappiness after the surgery.  The sooner you let go of bra size, the better. The best way to determine  your aesthetic goal is by in office sizing with a tight, unpadded bra, placing sizers or actual implants into the bra, and standing in front of the mirror with a shirt on. This will give you and the doctor immediate feedback, and the best information possible to the doctor about implant size necessary. Keep in mind that aesthetic goals takes a back seat to anatomic capacity, which is determined by physical examination. Go visit a few ABPS certified/ASAPS surgeons that specialize in breast surgery. Best of luck!

Determining Cup Size From Implant Size

There really is no reliable way to equate a specific implant size to a desired postop bra size.  That is because other variables, such as the amount of breast tissue and the dimensions of the chest, impact the final breast size.  It is important to keep the ultimate goal of breast augmentation in mind:  to achieve a breast size and appearance that meets your cosmetic goals while respecting your anatomy and changes in your breasts that may occur over time.  As you likely know, bra sizes vary frequently depending on style and manufacturer so placing too much emphasis on a particular cup size can distract you from the result you desire.

Cup size and cc

Thank you for your question. Many factors, in addition to the implant size in cc will determine your final cup size. Keep in mind that this is an additive process so that your result will be what size you bring to the table plus your implant size. As you can see the same size implant will naturally vary on what it will do to the overall size based on your starting size. Your consultation will answer these concerns for you in detail. Best of luck!

How do you know what cup size you will be by the ccs?

The best cosmetic result in any particular breast augmentation patient depends on a variety of factors, including: Your individual anatomy, desired outcome, realistic expectations, a thorough discussion with the plastic surgeon about the options, and an understanding of the pros and cons of any particular implant choice. Proper sizing is not just about the number of cc’s. The thickness of your tissue, breast dimensions which include the width, height, and projection, as well as chest wall width all need to be considered when choosing an implant. Trying on implant “sizers” of various shapes and volumes while wearing a tight t-shirt, bra, or bathing sit at a preoperative visit will help you and your surgeon choose the optimal implant. 

There are no manufacturers' standards for cup sizing in the bra industry. The cups of a 32 C and a 36 C are significantly different. Cup size varies from manufacturer to manufacturer and even within styles from any particular manufacturer. Nor is there a direct correlation between implant shape or size and cup size.

Keep in mind that following the advice from a surgeon on this or any other website who proposes to tell you exactly what to do without examining you, physically feeling the tissue, assessing your desired outcome, taking a full medical history, and discussing the pros and cons of each operative procedure would not be in your best interest. I would suggest that your plastic surgeon be certified by the American Board of Plastic Surgery and ideally a member of the American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are comfortable with. You should discuss your concerns with that surgeon in person.

How do you know what breast cup size you will be by the ccs?

Thank you for your question.  Cup size varies depending on the style and manufacture of bra that you wear. Very generally speaking it takes 150-200 cc of breast implant to increase by 1 cup size.  Patient consulted board certified plastic surgeon who has sizers available that can be placed into a bra to help you decide.  You can also do the Rice test which is described in the link below:
