What Cup Size Would a 500cc Implant Give Me?

Starting with a A cup, If i were to have a 500cc high profile silicone implant, roughly what cup size would that give me?? Would it make a difference in size if it were over or under the muscle? SO far i think i'm going with under

A 500cc implant adds approximately 2.5 cup sizes to your present measurement

Rule of thumb is that for every 200cc added a patient will experience a one cup increase over her present cup size. Using this rough calculation a 500cc implant would add two and one half cup sizes to your measurements.  In your case this size implant will enlarge you to between a C and D cup. I personally do not believe there is an appreciable difference between placing an implant subglandular versus submuscular. However, some would argue that a given implant appears smaller submuscularly.

It is very difficult to determine the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 500 cc implant to make her go from a “A” cup to a “C+” cup size does not mean that you will have the same result with the same size implant. . Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts). Using “want to be” photos however are useful if simply provided to the surgeon as I will further explain in the below link.

Depends on your baseline breast size and overall body dimensions

From an A cup, a 500 cc high profile implant would likely yield at least a very full C or D.

Below the muscle (most common) tends to appear a bit smaller than over.

Understanding Cup Size and CCs

Every women’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’s when determining breast volume.
In addition no two patients are ever 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 make a recommendation about implant size. For these reasons, consultation with a board-certified plastic surgeon is appropriate. This surgeon should be able to find the implant that creates harmony, balance, and proportion and ultimately accomplishes your aesthetic goals.
It’s also important to realize that placement of the implant beneath the muscle probably won’t impact breast size. However it will have significant long term benefits including a lowered rate of capsular contracture.

There is no way to guarantee a particular bra size. Bra sizing varies greatly between bra manufacturers and a C in one bra will be a D in another. What matters more than the assigned bra size is the way the implant looks on you. The best option for your body and aesthetic goals can be determined in a thorough implant sizing session.

Implant sizing depends on several factors. One of the most important factors is your breast width. Generally, your surgeon will measure your breast width, and then provide you with a range of implant sizes appropriate for your native breast size. There are more nuances to it than just what I've described, but this approach works for most women.

I usually have my patients bring in a large bra and a tight t-shirt to do sizing. I'll then choose 3-4 implants that I feel are appropriate, and have my patients place them in the bra under the tight t-shirt. My patients can then look in the mirror and get a good sense of what they will look like with the provided implant sizes. My patients like this approach and get a great idea of how they will look.

By using this technique, your surgeon can outline a range of appropriate implant sizes that will be aesthetically pleasing, and you make the final decision.

I hope this helps. Good luck!

Unfortunately, implant size does not correspond with a cup size.  Two women, with the exact same tissue and implants, can wear two totaly different sized bras.  It all depends on your breasts, chest size and shape, height, etc.  In general, though, a 500cc implant should make anyone in the D/DD/DDD cup size, depending on what chest size you are 32/34/36, etc.  I hope this helps.

"What cup size will this many cc give me?"

To answer this question, we need two data points. First, the number of CCs. And second, your base width diameter (BWD). Without knowing the BWD, it is hard to say.

As a ball-park, about 120 - 140 cc’s is a bra cup size. This may be more or less depending on the patient’s measurements.

I hope that answers your question on implants and cup sizes. It’s great that you’re doing this research. I always say that the best patients are informed patients.

You might also want to research your options for breast implants. Choosing the right implant is the number one concern among women considering breast augmentation. Did you know, there’s actually a way to select a implant shape, size, and profile that is perfect for you?

A term that I use with my patients for the perfect implant is the “Pony Implant”.

So what do I mean by “perfect”? Well, a Pony Implant has three qualities to it. First, the implant meets your beauty goals. For example, you want to your breasts to look fuller while still appearing natural.

Second, when you chose your Pony Implant, you walk out of your consultation 100% confident that you’ve chosen the right shape and size for you. In other words, you won’t be second guessing your decision, and you won’t be afraid of having gone too big or too small.

And third, after your procedure, you are thrilled with your results, and say, "I’m so happy. This is exactly what I wanted!"

That’s the Pony Implant. And the great news is that there is a simple process to go about finding yours.

This issue of selecting the right implant is so important when it comes to patient satisfaction or dissatisfaction that, again, I really encourage you to learn more about it.

Thank you for reading and best of luck on your journey!

Depends on where the bra is from!

Hi sailorsue,

The first question that most prospective patients ask themselves and their surgeon is: “How big should I go?” You might not want to hear this but I'm going to tell you anyway: you need to forget thinking about cup size. Women tend to think in cup sizes because that is how you buy your bras. The most common comment we hear is, “I’d like to be a C-cup”. When we hear this, we always ask more questions. This is because cup size for patients having breast augmentation is a very subjective measurement. Everyone wears their bras differently and every bra manufacturer makes them differently. You may be a 36C in one bra and a 34D in another. And when you check out all the different styles at your local Victoria’s Secret, you can understand why we say think proportion and shape, not cup size!

Every surgeon uses a different angle when working with patients to determine what size implants will give them the outcome they want. I am a fan of The Rice Test and "Wish For" photos from patients. These tell me exactly how much volume they are comfortable with and what they're picturing for themselves. 

What cup size or implant size you end up is really not as important as how happy you are with what you look like. My best advice is to be concerned with what you look like with a specified amount of added volume, not what that exact volume is. Patients focused on a cup size often end up with outcomes they are unhappy with and don't understand why they don't look the way they thought they would.

Breast augmentation and cup size

We do not perform augmentation procedures to achieve a specific cup size.  The reason is that cup size varies by bra designer.  Cup size is not standardized.  Rather, its about achieving your size goals. 

I help my patients select the correct size with two methods:

1. Dimensional planning and
2. A Gel Implant Sizing system

Dimensional planning – The measurements of your chest wall are taken. Also, the breast dimensions including the height, width, and current dimensions of each breast form the basis of dimensional planning. Based on these measurements, the implant size is recommended. This will give you a unique breast implant that is suited for your body frame. Even your fitness levels and other relevant criteria are taken into consideration. It is you who will decide what you are comfortable with.

Gel Implant Sizing system – During the preliminary breast implant consultation, you will be provided with an option to “try on” a variety of implant shapes and sizes. You can also visualize the possible outcomes of your surgery which helps you to get that perfect size to give you the shape that you longed for.

This way your preferences are known and you can then pick a range of implants that will “fit” just right to give a soft natural fuller look.

Best of luck!
