5’7, 110lbs, small framed, center of nipple to the other is about 7 inches. 300cc or 330cc for a C cup? (Photos)

Your pictures suggest that a 300-330 cc implant will achieve your goal of a C-cup, with the 300 being a smaller to middle C and the 330 leading to a larger C-cup. Either of these is likely to yield your target.

Thank you for your question. For you, as a small-framed, 5'7", 110-lb patient aiming for a natural C, the choice between 300 cc and 330 cc should be based on breast base width and profile, not on bra size labels. If your measured base width is ≤11.5–12 cm, a 300 cc moderate-plus typically results in a small/full C without overfilling. If your base width is closer to 12–12.5 cm, 330 cc moderate-plus can better match the footprint while still looking natural. Since 350 cc felt too big, 300 cc is the safer choice to avoid oversizing and tissue stretch. Confirm sizing with in-office sizers or 3D imaging during your in-person consultation with a board-certified surgeon to verify base width, tissue thickness, and profile before deciding between 300 and 330.

Patients often think in terms of cup size when considering augmentation. Unfortunately, devices are sized in terms of milliliters (cc) of volume. This can lead to some confusion when sizing. Additionally, it is important to remember that cup size itself is not standardized with variations from one manufacturer to another. Unfortunately, as many women can attest their cup size in an industry leader such as VS is not necessarily transferable to another brand.
Another point which is often under appreciated is that of anatomy and starting point. Any implant will add volume to the volume which is already present. The implant is additive. A particular volume will not necessarily confer the same cup size to different patients (often times it will not even confer the same cup size to different breasts in the same individual...remember they are "sisters" not "twins").
A general rule of thumb is that 125cc can represent somewhere between 1/2 to a full cup size increase. Smaller volume differentials (25-50cc) are typically less consequential representing a volume change of less than a shot glass. However, I have found these numbers, at least anecdotally, to be of little help. Patients often present with notions/goals which do not correlate with these sorts of sterile volumetric assessments.
When sizing patients, there are a number of useful tools including:
-3D imaging (has the added benefit of offering a volumetric analysis of the pre-operative breast)
-Breast sizers (rice bags)
-Goal photos
I also recommend that patients commit to a particular look rather than a cup size. Once a patient settles on a look that pleases them the overall cup size increase becomes less relevant.
With regards to your specific question, I would not struggle over small variations in size. 30 cc represents less volume than a shot glass and is unlikely to make or break a result.
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size breast implants. 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.

Unfortunately, you have not told us your bra size. If you are size 32 or 34, each 100 cc of implant corresponds to 1 cup size change. If you are size 36 or 38, each 200 cc of implant corresponds to 1 cup size change. From this, you can determine the amount required to achieve your desired goal.

Best Wishes,

Thank you for sharing your question and photographs. I would recommend either seeking additional consultations that fully inform you of your treatment options, and can give you the option of trialing various sizers in various profiles to provide you the best visual demonstration of what your outcome may approximate.

Hello. With your height, weight, and petite build, 300cc is a safer option if 350cc seemed too large and you're looking for a natural C cup. The difference between 300cc and 330cc is minimal (approximately half a size), but if you'd rather not go overboard, 300cc would be the best choice. You can contact us at 829-554-6062 for a quote.

On a small frame like yours, a 300–330cc implant typically results in about a 2 cup size increase, which aligns well with your goal of reaching a C cup from an A cup.
From my experience, 330cc with a moderate profile is a reasonable choice. It's important to note that implants can appear about 10% smaller once placed inside the body, so what may seem slightly big during a try-on may look more natural post-op.
Ultimately, the difference between 300cc and 330cc is subtle, but if 350cc felt too big, 330cc should still give a full, natural result without being overwhelming.

I encourage you to return to your surgeon's office to discuss implant selection. Many have sample implants you can "try on" to give you an idea of how you may look after surgery. If you felt the 350cc implant was too large you may want to lean toward the 300cc implant if you want a more conservative look. Because you have more minimal breast tissue, the volume of the implant is similar to what you'll have after surgery.

Based on your nicely posted photos, a 30 cc difference is less than 1 ounce of fluid so a 300 to a 330 isn’t really much difference. The number one complaint after breast implant surgery as I wish I would’ve gone bigger so error on the side of a larger implant and use a 330. That is an over Internet opinion with no imp person examination or virtual examination. Maybe return for a secondary
In person consultation….
