Will 300cc Saline Breast Implants Result in a C Cup?

Breast size depends on a few factors -- how big you are around, how much breast tissue you have, and what size implant you choose. If you are a 32 -- an a cup is much smaller than a 40 A.
In the typical 32 A with little native breast, a 300 to 325cc will give you a mid C appearance. The best way to tell is to stick a 300 cc sizer in the bra you want to wear and see what it looks like.

Thank you for your question and for sharing your photo. Size of the implants can be very personal choices that a patient makes. In many cases, patients can go from a A cup to a D cup or larger. In our practice, I begin by asking whether you are looking for more projection or perkiness and whether you mind have some of the breast tissue push outwards on the side. In addition, I ask you to try on different external sizers to give you a sense of what your breast may look like and the feel of extra volume in the breasts. In addition, I take details measurements of the breast including the base diameter of the breast. Your volume range and the breast shape preferences helps me the further guide you in your implant selection and to give you guidance on what the breast might look. It is more important to go through this process and then find a bra that fits afterwards.  It is very likely that you will go up a couple bra sizes, but it is hard to say depending on which bra manufacturer whether it will be a C or D.

Every woman’s
idea of cup size is different and for this reason, most plastic surgeons prefer
other methods to determine breast size.Furthermore, cup size doesn’t easily translate into cc when determining
breast volume.In addition, no two
patients are ever exactly alike.They
have unique anatomic findings, individual starting points, and specific
aesthetic goals.In the absence of a physical
examination and pictures, it’s virtually impossible to answer your question
regarding implant size.Under these
circumstances, it might be helpful to have further consultations with your
plastic surgeon.Your surgeon should be
able to find the implant that creates harmony, balance, and proportion and
ultimately accomplishes your aesthetic goals.If you continue to have concerns about your breast size, there’s no better
time to get your questions answered than before surgery.

Hello! Thank you for your question. In general, implant size does not correlate with bra cup size. The cup size itself will vary from manufacturer to manufacturer as well as who is doing the actual measurements. Thus, cup size is never a reliable indicator for your breast size. I typically encourage my patients not to communicate her desires in cup size but more on the actual look and appearance. Good communication between you and your surgeon of your expectations is warranted - choosing your surgeon wisely is the first step. Discussion of your wishes and having an honest and open dialog of your procedure is mandatory (e.g, implant type, incision, placement, lift, etc). I have found that photographs brought by the patient is helpful to get a visualization of the appearance you wish for in terms of size, shape, fullness, etc. In addition, your surgeon's pre and postoperative photographs should demonstrate a realistic goal for you. Once this has been accomplished, allow your surgeon to utilize his/her best medical judgment during the procedure to finesse the best possible result for you after preoperative biodimensional planning and fitting the right implant for your breast width. Hope me that this helps! Best wishes for a wonderful result!

Although the measuring technique for determining cup size is precise, the results of these measurements are not. The same is true with two patients that have C cup breasts. This is why physicians tend to use volume (cubic centimeters or cc) as a more accurate measurement. Note: If you are trying to figure out what breast implant size you want to obtain, you can try the sizing tool available through b4bra.com or read the articles about measuring there.

The question of what implant size will result in a specific cup size is a common one but also an unanswerable one. We are stuck with the cup system from the Warner Bros. Corset Co. in the 1930's, a more modest time when breast size had to be inferred from indirect measurements. So the whole chest determines the cup, not just the volume of the breasts. My suggestion is to choose an implant that gives you the look you want by trying sizers in a bra of the desired cup size but then forget about the cup. Your surgeon can then help translate this into the necessary implant size, which will be a little bit larger than the sizer in order to give the same look.

There is no way to exactly predict bra size after trying on implant sizers. This is a good approximation of what the bra size will be following the surgery. The problem is that each bra manufacturer has different shapes and body contours that cause differences in bra cup sizes. For instance, Victoria Secret generally upsizes cup size and Sears is typically smaller. If you like what you see with the sizers, you should be happy. I usually recommmend going one 30cc's larger than what you have tried on.

There is no absolute volume that gives a cup size a value. In addition to arbitrary decisions by the manufacturer, the cup designation is a function of the chest wall circumference (without the breasts included) and the relative projection delivered by the breast volume. A woman who is 6'4" will demand a much larger volume on her chest wall to be a "C" cup than a woman 4"11".
On balance, the average woman of height (5'5") and build will be taken from an "A" to a "C" cup by a 300 cc implant. I prefer to use pictures to determine the desired size of the patient lest there be any misunderstanding between the surgeon and patient as to precisely what a given cup size looks like.

This is hard to estimate without picture and measurements.  Unfortunately, there is not a general rule of thumb or objective criteria to implant selection to replace an in office exam and good communication with a board certified plastic surgeon.

Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.

The use of sizers in your bra  preoperatively does not accurately correlate with the size of breasts achieved with sub muscular implants. I think that it is very important that you communicate clearly with your surgeon to maximize the chances of achieving your desired breast size.

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

Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.

I use  intraoperative sizers and place the patient in the upright position to evaluate breast size. The patient's goal pictures are hanging on the wall, and allow for direct comparison.

I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible.

I hope this helps.
