What Size Are 200cc, 300cc, 400cc, and 500cc Breast Implants?

What size are 200cc, 300cc, 400cc, and 500cc breast implants? As a general guide, 200cc is a modest implant volume, 300cc offers a more noticeable enhancement, 400cc adds fuller volume, and 500cc represents a more substantial increase. But the same volume can look very different on different bodies.

Could 200cc take you from an A cup toward a B? Could 400cc take a B cup toward a D? Both are possible examples—not dependable conversions. Your starting breast tissue, band size, chest width, and implant dimensions matter.

If you are still exploring your options, start with our guide to how to choose the right breast implant size or use the Breast Implant Size Calculator to organize the sizes you want to compare.

Breast Implant CC Sizes at a Glance

These cup-size examples illustrate goals some women may have, not outcomes you can predict from cc alone. Implant volume measures the implant, not the final total volume of your breasts.

What Size Are 200cc Breast Implants?

200cc breast implants are a relatively small-volume option that may appeal to women looking for a modest enhancement. A woman starting at an A cup might hope for a fuller B-cup appearance, but 200cc does not guarantee that result.

On a petite frame with little existing breast tissue, even 200cc can be noticeable. On a broader frame, the same volume may look subtler. You might notice more fullness in a fitted shirt, a change in bra fit, or a slightly more defined silhouette.

Is 200cc enough to make a difference?

It certainly can be. If you want to compare a modest enhancement with something more noticeable, consider experiencing 200cc breast implant sizers alongside 250cc and 300cc. The difference may be easier to appreciate on your own frame than in someone else’s photographs.

What Size Are 300cc Breast Implants?

300cc implants offer a moderate volume increase that can look noticeably fuller than 200cc. Someone starting with an A cup might be hoping for a C-cup appearance, but the result depends on anatomy and bra sizing.

With 300cc, the change may be more apparent under fitted clothes and from the side. Yet the real question is not just what you see in a mirror. How does that amount of volume feel as you walk, drive, or go about an ordinary day?

Is 300cc considered large?

Not necessarily. 300cc may look quite full on a small frame but more restrained on someone with a wider chest. Our 300cc sizers let you explore that volume externally; they do not predict your surgical outcome.

What Size Are 400cc Breast Implants?

400cc implants generally create a fuller enhancement than 200cc or 300cc. A common question is: “If I am a B cup, will 400cc make me a D cup?” That is possible for some women, but not a reliable expectation for everyone.

A 32B and a 38B do not have the same cup volume, and implant profile also matters: two implants with the same cc can differ in width and projection. Our 350cc profile comparison shows how, and the American Society of Plastic Surgeons explains implant profiles in more detail.

With 400cc, you might notice fuller projection, a stronger silhouette in fitted clothes, and more awareness of added volume during movement.

Will 400cc look too big?

“Too big” is personal. You may love the appearance of 400cc in a photograph but prefer 350cc when you wear it under your own clothes. Or you may find that 400cc looks more proportionate on your frame than you expected. Try 400cc sizers as part of a comparison rather than judging the number alone.

What Size Are 500cc Breast Implants?

500cc is a relatively large implant volume that can create a substantial increase in fullness. On a petite woman, it may look very pronounced; on a taller woman with a broader chest, the same volume may appear more proportionate.

Could 500cc take someone from a B cup to a DD? Possibly, but there is no dependable cc-to-cup formula. What matters is your starting anatomy, the implant dimensions, and the look you want to achieve.

Are 500cc breast implants too large?

There are two separate questions: whether you personally like that much volume, and whether the implant is medically appropriate for your anatomy. You can explore your preference using 500cc external sizers, but only a qualified plastic surgeon can assess surgical suitability.

Deciding between the top two sizes? See 400cc vs. 500cc Breast Implants: How Much Bigger Is 500cc?

The FDA’s breast implant information is a useful resource for understanding implant risks and the importance of informed surgical decisions.

Each Step Is 100cc, but It Isn’t the Same Jump

200cc, 300cc, 400cc and 500cc are evenly spaced, 100cc apart. But each 100cc step is a smaller share of the volume before it. That is one reason the move from 200cc to 300cc can look more dramatic than the move from 400cc to 500cc.

These percentages describe the implant only. Your own breast tissue is part of the total, so the visible change in your overall breast size will be smaller than the implant percentage. A 33% larger implant does not mean breasts that look 33% larger.

What this means in practice: if you are deciding at the lower end, a 50cc difference (200cc vs. 250cc) may be worth comparing. At the higher end, you may need to compare sizes further apart before the difference feels meaningful. Use the four sliders above to see each step on the same model.

The better question is not “What cup size equals 400cc?” but “How does 400cc look and feel on my body?”

How Many Cup Sizes Will These Volumes Add?

There is no dependable cc-to-cup formula. Cup sizes change with band size and bra brand, and your starting tissue matters. If you are working from a cup-size goal, see A Cup to D Cup Breast Implants: How Many CCs? or, for a band-size example, I’m a 34A and Want to Be a 34C.

How Can You Try Different Breast Implant Sizes Before Surgery?

Photographs and cup-size estimates can help you begin. But they cannot show you exactly how added volume will look and feel under your everyday clothing. If you are new to the idea, start with how to try breast implant sizes at home.

The Oumènta Custom Breast Implant Sizer Kit lets you select three different volumes to experience at home with the Oumènta Pocket Bra. For example, if you are considering 400cc, you might choose 350cc, 400cc, and 450cc. If you are still deciding between a modest and a fuller enhancement, you could compare 200cc, 300cc, and 400cc.

Wear a fitted T-shirt, a loose sweater, or a favorite dress. Notice how you feel while walking, shopping, driving, and seeing yourself in mirrors throughout the day. Because the sizers are discreetly held inside the Pocket Bra, you can explore your preferences in ordinary situations.

We suggest beginning with at least six hours per session and at least one day with each volume. Continue for as long as you want until you feel more confident about your preferences. The goal is to communicate what you like to your surgeon—not to select a surgical implant independently.

If you want to understand why taking time with this decision matters, see our breast implant size satisfaction research summary.

Frequently Asked Questions About Breast Implant Sizes

Is 200cc enough to go from an A cup to a B cup?

It may be for some women, but it is not guaranteed. Starting breast tissue, band size, and anatomy influence the result.

Can 300cc breast implants make you a C cup?

Possibly. Some women considering 300cc hope for a C-cup appearance, but cc cannot reliably predict a bra cup size.

Will 400cc breast implants make me a D cup?

That is possible for some women starting around a B cup, but band size, existing tissue, and implant dimensions can change the outcome.

Are 500cc breast implants considered large?

500cc is a relatively large implant volume, but the visible effect varies with frame size and starting anatomy.

Is the difference between 300cc and 400cc noticeable?

It can be. The difference is 100cc per implant, which is approximately 33% more implant volume—not a 33% increase in total breast size.

Can sizers show exactly what I will look like after surgery?

No. External sizers help you explore added volume under clothing but cannot reproduce the exact shape, feel, or result of surgically placed implants.

The Bottom Line: Which Breast Implant Size Is Right for You?

200cc, 300cc, 400cc, and 500cc represent different amounts of implant volume, but the number alone cannot tell you whether a result will look modest, natural, full, or dramatic on your body.

Experience different volumes, pay attention to how they fit your everyday life, and discuss your preferences with a qualified plastic surgeon. The goal is not simply to choose a number. It is to understand what you like before making a surgical decision.
