When considering a breast augmentation, one of the first things you will need to decide on is your breast implant size. This may sound like an easy thing, but it is actually a bit more challenging than you would figure.
Do breast implant sizes correspond to the cup size I want?
No. Breast implant sizes are measured in cubic centimeters (cc) and not bra cup sizes. Also, the same implant size can look completely different on two different people, depending on their body shape, chest width, amount of natural breast tissue they have, and the profile of their implant.
Surgeons use a series of measurements, your specific anatomy, and the results you desire to choose the implant size that will work best for you.
About Breast Implant Sizes
Breast implant sizes are based on volume and not typical bra sizing. Many patients get confused when they are researching breast implant sizes online or begin looking at comparison charts.
Some of the reasons for the confusion include:
Breast implants are measured in CC’s and not cup size
- CC stands for cubic centimeters, which is a way to measure the volume inside the implant.
- The number shown, like 300 cc or 450 cc, means how much saline or silicone gel the implant holds and does not translate to a direct or specific cup size.
- The larger the number, the more filling there is inside of the implant.
Bra cup sizes are not consistent across brands
There are so many different manufacturers that produce bras, and the sizing is not standard across the board. This can cause confusion about what your actual bra size really is.
Everyone is different
The same implant size can look different from person to person because of the differences in their anatomy.
Only Use a Chart Of Breast Implant Sizes As a Guide
A breast implant sizes chart can be helpful when you are first starting to look at all of the options available and you are educating yourself so you can make the best decision. There are many things besides the implant size that will affect your final results, so it is not enough to just rely on a breast implant sizes chart.
Some of the things that will determine how your breasts will look after your augmentation include your:
- Chest width and the shape of your ribs
- Natural breast tissue volume
- Skin elasticity
- Implant profile and where the implant will be placed.
Breast Implant Sizes: A Comparison Chart By Volume
A chart can give you an idea of the changes you can expect with each size implant, but it cannot replace a consultation with a surgeon, like Dr. Min, who will evaluate your anatomy in person.
Below is an approximate breast implant sizes chart to help explain how different cc ranges may look.
| Implant size (cc) | Approximate change | Estimated Results |
|---|---|---|
| 150–200 cc | Subtle increase | Often chosen when desiring very natural-looking but minimal enhancement. |
| 200–300 cc | Mild to moderate increase | Usually chosen for balanced, natural-looking results with mild enhancement. |
| 300–400 cc | Moderate increase | Most frequently selected range to create noticeable change that still looks natural. |
| 400–500 cc | More noticeable increase | May be good for certain body frames and depending upon desired results. |
| 500+ cc | Dramatic increase | Not a common choice and requires careful planning for proportion. |
These are only general ranges, and results will vary based on your body type and implant style.
What Patients Should Consider Before Using A Breast Implant Size Chart
- Bigger is not always better for everybody.
- An in-person consultation will provide the most information.
- Bring reference photos of your desired results.
- Describe your preferences for natural vs. fuller appearance.
- Ask about sizing tools or 3D imaging.
- Discuss your expectations for how clothing will fit.
What Is A Breast Implant Profile?
The breast implant profile is a measurement of how far the implant will project forward from your chest wall. Aside from the breast implant cc volume, the profile size also significantly affects how the final result will look. Two implants with the same breast implant cc sizes can look very different depending on the profile chosen.
| Implant profile | How it looks | Best suited for |
|---|---|---|
| Low profile | Has a wider and flatter shape with less forward projection. | Normally chosen for women with wider chest frames or patients desiring a very subtle enhancement. |
| Moderate profile | Has a balanced projection with a natural slope. | Most common option for those with an average chest width to achieve a natural, enhanced appearance. |
| High profile | Offers more forward projection and a rounder shape. | Usually chosen for those with a narrow chest frame or women who desire more visible fullness. |
How implant profile affects breast implant sizes
The implant profile can change how breast implant sizes appear on the body, even when the cc volume is the same.
- Low profile implants spread volume more horizontally.
- Moderate profile implants balance width and projection.
- High profile implants concentrate the volume forward to create more projection.
How A Surgeon Helps You Choose The Right Implant
Two patients with the same breast implant cc sizes may achieve different results because there are many things to consider. Your surgeons will usually combine the cc volume, implant profile, and your chest measurements to create natural-looking, balanced breasts that fit your body frame.
Your body frame and breast width
Your surgeon will use your physical measurements to help select a size that will look proportionate to your body. In addition to the measurements already mentioned, your surgeon will most likely also include your shoulder and hip proportions. All of these details can help determine how an implant will sit on your frame.
Your goals and lifestyle are also considered
The results you are looking for are also very important and considered when choosing breast implant sizes.
- Subtle or more dramatic enhancement
- Natural-looking or noticeable fullness
- Ongoing plans for exercise and activity level
- Goals for how your clothing fits.
- Long-term expectations for comfort
Combining A Breast Lift With Implants
Breast implant sizes enhance the volume of your breasts but do not do anything for their position. A breast lift is performed to correct sagging and breasts that have lost their youthful shape. These are separate concerns, but they can be fixed at the same time. Your surgeon may talk with you about combining the procedures for optimal results.
- Breast augmentation for volume.
- Breast lift for repositioning.
- Combining the surgeries to achieve both shape and fullness.

FAQs
What does “cc” mean in breast implant sizes?
CC stands for cubic centimeters and is the fluid measurement of the implant volume.
How accurate is a breast implant sizes chart?
A breast implant sizes chart is only an estimate to use as a guide. It can give you a basic idea of volume differences but cannot guarantee exact results because every person’s anatomy is different.
What is the most common breast implant size range?
Many patients choose implants in the 300–400 cc range, but the right size depends on your body frame, natural breast tissue, and your personal preferences.
Can I choose implant size based on my cup size?
No. Cup size alone is not a reliable way to choose breast implant sizes. Surgeons use a combination of measurements, body proportions, and the look you desire to achieve to choose the best implants for you.
