The Short Answer
How do I choose the right breast implant size?
The number of cubic centimeters (ccs) doesn't determine whether your breast augmentation will look natural or proportional. What matters most is how the implant fits your chest width, existing breast tissue, and overall body frame. A 300cc implant can look dramatically different on two women, and my goal is always to select an implant that complements your anatomy rather than forcing your anatomy to accommodate an implant.
Why the CC Number Is the Wrong Place to Start
Patients search by cc because it's the one number they can find. But a cc is a volume, not a look. Put the same volume on a narrow chest and a wide one and you'll get two very different results. The infographic below shows the four inputs Dr. Piazza actually sizes from.

Breast base width
Sets the implant's maximum diameter

Tissue thickness

Skin and nipple position
Elasticity, and whether a lift is in play

Then your goal decides within that range
How Dr. Piazza Picks a Size at Your Consultation
1 · Listen
I start by listening to what you want. Are you looking for a subtle enhancement, more upper-breast fullness, or a noticeably fuller appearance?
2 · Measure
Then I evaluate several important anatomical measurements, including your breast base width, chest wall dimensions, existing breast tissue thickness, skin elasticity, and nipple position.
3 · Try
Sizers in your bra and 3D imaging let you see the options on your own body, not someone else's.
4 · Decide
We narrow to the implant that gives you the look you described and that your tissue can support long term.
What I bring to the consultation goes far beyond measurements and implant sizes. Over my 16 years of experience in breast enhancement, revision surgery, and aesthetic breast reconstruction, I've developed a deep understanding of breast anatomy, proportions, and what it takes to create a beautiful, natural result.
But I believe what truly sets my approach apart is my ability to listen deeply to my patients—not just to what they're saying, but to what they're really hoping to achieve. I have a unique ability to translate those desires into a surgical vision, combining my experience, aesthetic judgment, and understanding of their anatomy to guide them toward a result that feels authentically theirs.
My patients don't need to know exactly what implant size they want. My role is to understand how they want to look and feel, and then use my experience to help bring that vision to life. — Dr. Rocco Piazza
Dr. Piazza on why the same size looks different on different bodies, and the price tissue pays for very large implants.
Real Patients, Real Sizes
Here's what four different volumes look like on four real Austin patients. Look at the frame, not just the number: the 275cc result on a 5′2″ patient reads as proportional, not big.

Athletic and Wide-Shouldered Patients
Two things change for women who train or have a broad frame. A wider chest can carry more volume before it looks large, so the right implant is often bigger in cc than a narrower patient would choose. And an implant that is too big or too wide can get in the way of lifting, running and yoga. Placement matters too: Preservé leaves the chest muscle untouched, which is one reason Dr. Piazza favors it for active women.
What “Too Big” and “Too Small” Regret Looks Like
Too big
Patients may feel their breasts overwhelm their frame, interfere with exercise, or simply no longer reflect how they want to look. Larger implants can also place additional stress on breast tissues over time, contributing to stretching, implant malposition, and the potential need for revision surgery.
Too small
Some patients wish they had chosen more fullness, particularly in the upper breast or in clothing. This can happen when the original decision was driven by fear of looking unnatural rather than a clear understanding of how different implant sizes would look on their body.
Dr. Piazza's Philosophy
After years of performing breast augmentation and revision surgery, I've learned that the best results come from respecting the patient's anatomy.
I frequently see women seeking revision because their implants are too large, too wide, or no longer fit their lifestyle. That experience has reinforced my belief that bigger isn't necessarily better.
I don't want to give you the largest implant your body can accommodate. I want to give you the implant that creates the result you love while respecting your tissues for years to come. — Dr. Rocco Piazza
Breast Implant Size FAQ
How many cc's is a cup size?
There's no fixed conversion. The same implant adds a different amount of visible fullness depending on your chest width, existing tissue and frame, which is why Dr. Piazza sizes by measurements and goals rather than a cc-per-cup chart.
What does 150cc look like?
A subtle, natural enhancement, often called the “ballerina” look. See a real 150cc Motiva result.
Is 300cc big?
It depends entirely on the body it's placed in. A 300cc implant can look dramatically different on two women; on a narrow chest it can look full, on a wider frame it can look modest.
Should I size up so I don't regret going too small?
Not automatically. Too-large implants are one of the most common reasons women come in for revision. The better protection against regret is trying sizers and seeing real patients with your build before surgery.
What size is best for athletic women?
Usually one that stays in proportion to the chest wall and doesn't get in the way of training. See breast augmentation for active women.
