A comprehensive guide to understanding breast implant volumes and how they translate to cup sizes, with a special focus on achieving a natural C cup appearance.
Wondering how many CCs equal a C cup? You're not alone. This guide breaks down cup size conversions, implant volume ranges, and the most important factors surgeons consider when sizing for breast augmentation.
This guide provides general ranges, but for a personalized estimate, we recommend using a calculator that accounts for your specific measurements.

When plastic surgeons discuss implant sizes, they use cubic centimeters (CCs) as a measurement of volume, not cup size. Cup sizes are not standardized measurements—they vary between bra manufacturers and are influenced by band size, whereas CCs are precise units of volume.
This volume-to-size relationship is fundamental to understanding why there's no one-size-fits-all answer to "how many CCs make a C cup?"
The same implant volume can result in different cup sizes depending on numerous factors:
Many patients arrive at consultations with a specific CC number in mind, believing it will guarantee a certain cup size. This one-dimensional thinking overlooks the importance of proportion, anatomy, and personal aesthetic goals. Surgeons focus on finding the right volume for your individual body, not hitting an arbitrary CC number.
While no chart can provide a perfect prediction, the following table offers approximate CC ranges that typically correspond to a C cup across different band sizes. These estimates assume moderate profile implants and average tissue characteristics.
| Band Size | From A to C (CC Range) |
From B to C (CC Range) |
Typical Final C Cup Volume |
|---|---|---|---|
| 30 | 230-280cc | 150-180cc | 230-280cc |
| 32 | 250-300cc | 170-200cc | 250-300cc |
| 34 | 280-330cc | 190-220cc | 280-330cc |
| 36 | 300-350cc | 200-250cc | 300-350cc |
| 38 | 330-380cc | 220-280cc | 330-380cc |
| 40 | 350-400cc | 240-300cc | 350-400cc |
The "From A to C" column shows how many additional CCs you'd typically need to increase from an A cup to a C cup.
The "From B to C" column shows the typical volume increase to go from a B cup to a C cup.
The "Typical Final C Cup Volume" represents the approximate total volume (natural tissue + implant) that creates a C cup in a person with that band size.
Remember, these values are general guidelines. Your surgeon will assess your unique anatomy, measure your chest width, evaluate skin elasticity, and consider your aesthetic goals before recommending a specific implant size.
While cup size conversion is useful, not everyone should pursue implants. Learn about who may be medically ineligible for breast augmentation.
Implant profile—how far the implant projects forward from the chest wall—plays a crucial role in achieving a C cup appearance, especially on different frame types. The same volume (CC) in different profiles can create dramatically different looks.
For C cup: 275-350cc (depending on band size)
Best for: Wider chest walls, those wanting subtle volume
Characteristics: Wider base width, less forward projection, creates a more subtle slope and natural appearance
Note: May require more CCs to achieve a visual C cup compared to higher profiles
For C cup: 250-330cc (depending on band size)
Best for: Average chest widths, balanced results
Characteristics: Balanced base width and projection, creates natural-looking fullness
Note: Most commonly used profile, offers versatile sizing options
For C cup: 220-300cc (depending on band size)
Best for: Narrower chest widths, those wanting more projection
Characteristics: Narrower base width, more forward projection, creates more prominent cleavage and upper pole fullness
Note: Creates more dramatic appearance with less volume
Women with narrower chest walls face a sizing dilemma: standard moderate profile implants in C cup volumes (250-330cc) are often too wide for their frames, potentially extending into the armpit area and creating an unnatural appearance.
"When a patient with a narrow chest wall wants a C cup, I often recommend high profile implants. This allows us to achieve the desired volume and projection without implants that are too wide for the chest. The higher profile concentrates the volume where it matters most—at the center of the breast—rather than extending toward the sides. This creates a beautiful, proportionate C cup without the width issues of moderate or low profile options." — Dr. Sarah Chen, Board-Certified Plastic Surgeon
The same implant volume creates dramatically different visual impacts depending on a woman's height, frame size, and overall proportions. This is critical to understanding why "300cc to get a C cup" is an oversimplification.
| Body Type | Typical CC Range for C Cup | Visual Impact | Considerations |
|---|---|---|---|
| Petite 5'2" or shorter Narrow frame |
220-280cc | Appears quite full, proportionately larger due to small frame | May need high profile to avoid side fullness Higher risk of appearing "obviously augmented" |
| Average 5'3"-5'6" Medium frame |
270-320cc | Balanced, proportionate enhancement | Most versatile options Moderate profile often ideal |
| Tall 5'7" or taller Average width |
300-350cc | Appears proportionately smaller due to larger frame | Often needs more volume to create visual impact May still look natural with larger sizes |
| Athletic Broader shoulders Wider chest wall |
320-380cc | Needs more volume to balance broader upper body | Low or moderate profile better accommodates wider chest Pectoral muscle development may affect sizing |
| Full-figured Wider frame More natural tissue |
350-400cc | Implants blend with existing tissue for natural look | May need less volume increase if starting with more tissue Wider chest accommodates wider implants |
To illustrate how dramatically body type affects implant appearance, consider 300cc moderate profile implants on different frames:
This visual difference explains why focusing solely on cup size or CC volume without considering body proportions often leads to sizing dissatisfaction. For optimal results, implant selection should be based on comprehensive measurements, not just target cup size.
The C cup is frequently described as the "goldilocks" size—not too small, not too large—and is often requested for its balance between enhancement and natural appearance. Here's how surgeons approach creating beautiful, natural-looking C cups.
Surgeons measure your breast base width—the horizontal distance from where breast tissue begins to where it ends. This critical measurement determines the maximum implant width that will look natural on your chest.
For a natural C cup: The implant diameter should closely match or be slightly narrower than your natural breast base width. An implant that's too wide extends unnaturally into the armpit area or creates excessive cleavage medially.
The amount of existing breast tissue significantly affects how implants appear and which size creates a C cup.
Surgeons evaluate:
For a natural C cup, surgeons match implant profile to chest width:
Placement significantly affects how many CCs create a C cup:
"When a patient asks for a natural C cup, I focus on the 'natural' as much as the 'C cup.' This means selecting an implant that respects their anatomy—one that has the right width for their chest, appropriate projection for their tissue, and volume that enhances without overwhelming their frame. Sometimes this means using slightly smaller implants than they initially expected, but the result is a beautiful, proportionate enhancement that doesn't scream 'augmented.' The goal is for people to notice you have a great figure, not that you have implants." — Dr. Michael Tanaka, Board-Certified Plastic Surgeon
For patients considering implant replacement (revision or exchange surgery), understanding how many CCs it takes to increase a cup size with existing implants is essential for setting realistic expectations.
These general guidelines help estimate cup size changes when replacing existing implants:
| Current Implant Size | Current Cup Size | New Size for C Cup | Volume Increase |
|---|---|---|---|
| 200cc | Small B | 350-400cc | 150-200cc |
| 250cc | Full B | 375-425cc | 125-175cc |
| 300cc | Small C | 375-425cc | 75-125cc |
Many patients believe that adding 100cc to their current implant size will guarantee a one-cup size increase. While this can be a reasonable estimate, the relationship isn't always linear. Tissue stretching from existing implants, pocket changes, and potential profile differences all influence the outcome. Additionally, larger sizes require more volume increment to achieve the same proportional increase.
When replacing implants, consulting your surgeon about how your tissues have adapted to your current implants is essential for accurate sizing expectations. Often, the stretched breast pocket and tissue adaptation mean that you may need slightly more volume than you expect to see a significant difference.
Understanding common sizing regrets can help you avoid disappointment when selecting implants for a C cup appearance. Here are the most frequent mishaps:
The mistake: Fixating on a specific cup size without considering proportions.
The reality: A C cup looks dramatically different on different body types.
Better approach: Focus on overall proportion and how the implants balance with your frame, rather than aiming for a specific letter.
The mistake: Choosing implant size based on a friend's results or photos.
The reality: Your unique chest width, tissue characteristics, and frame size dramatically affect results.
Better approach: Trust your surgeon's measurements and recommendations based on your specific anatomy.
The mistake: Choosing smaller implants out of fear of looking "too done."
The reality: Studies show that approximately 30% of revision surgeries are performed because patients wish they had chosen larger implants.
Better approach: Use sizers during consultation to visualize results and consider the upper range of your surgeon's recommended sizes if between options.
The mistake: Fixating on a specific CC volume you've heard creates a C cup.
The reality: A 300cc implant can create dramatically different cup sizes depending on profile, placement, and anatomy.
Better approach: Focus on the visual appearance in consultation using sizers rather than getting attached to a specific CC number.
"When I got my implants, I was fixated on being a C cup. I told my surgeon I wanted exactly 300cc because I read online that was a C cup. He suggested 350cc based on my measurements, but I insisted on 300cc. Six months after surgery, I was disappointed to find I was still a B cup in most bras. My surgeon explained that my wider chest and taller frame meant the 300cc volume was distributed differently than it would be on a smaller person. If I could do it again, I'd listen to my surgeon's recommendation rather than focusing on that specific number." — Allison, 34

No, 300cc is not always a C cup. The resulting cup size depends on several factors:
For example, 300cc might create a C cup on a 32 band but only a B cup on a 36 band.
For most women, it takes approximately 175-250cc to increase from a B to a C cup. This varies by band size:
Existing breast tissue and implant profile also affect the final result.
Yes, high profile implants often appear larger than moderate profile implants of the same volume. High profile implants:
While the actual volume is identical, the visual impact can seem significantly different.
Implants look different on various body types because of:
The same 300cc implant will appear much larger on a petite 5'2" frame than on a 5'9" athletic build.
The most common sizing mistake is focusing solely on cup size rather than considering overall proportion and individual anatomy. Many patients request a specific cup size without understanding that implant sizing should be based on:
This misunderstanding often leads to choosing implants that are too large or too small for one's frame.
