What size breast implants should I get?

Just like every woman’s chest, no two bras are identical when it comes to sizing. You might be a 10C in your favourite brand and shape, but need to purchase a 10D in another brand you’re trying out for the first time.

It’s really a wonder then that we use “cup size” as the benchmark for measuring breast size when it can vary so frequently between not only brands, but styles and shapes of bra, too.

However, cup size has become our default measurement, even though it can mean so many different things to different women.


Well, did you know that the “C” of a “10C” and a “14C”, for example, are not actually the same size?

Because the number represents the underband sizing, the letter adjusts in size to account for body width as well as breast projection. The equivalent cup size (regardless of the band size) can actually be a different letter altogether.

How do you remember it?

Think of it like this: when you go down a band size (the number), go up a cup size (the letter) – and vice versa.

Some examples:

  • 12B is the same cup size as a 10C. It’s also the same as a 14A
  • A 10E is the same cup size as a 12DD or a 14D
  • A 16B is the same cup size as a 14C or 12D

How are breast implant sizes “measured”?

No doubt you’ve heard the term “CCs”? This is a standardised measure of breast implant sizes that we use in the medical world.

But what exactly is a “CC”?

CC stands for “cubic centimetre” and is the most common measure around the world.

It’s easy to remember: the higher the number of CC in an implant, the larger it is. That means a 600CC implant is larger than a 400CC one.

Breast implant sizes generally range from as little as 200CC to 600CC, but of course there is no stock-standard sizing recommendation.

What should I consider when it comes to breast implant sizing?

Existing breast tissue

“400CC” isn’t always so clear cut, especially if you already have existing breast tissue.

During your consultation, we take a look at the shape and volume of your existing breasts to determine how your current chest may affect the size you choose.

This is particularly important for women who have had babies and have breastfed, or have lost significant amounts of weight but still carry volume across their chest.

In fact, this will also help us understand whether what you want is indeed breast implant surgery, or perhaps a breast lift, instead.

Your build

Most candidates who come in for a consultation envisage a “natural” look. But what does than mean?

Many patients want:

  • Their new breasts to compliment their existing body shape
  • To be in proportion to their curves, waist, chest, and hips
  • The contour of their breasts to be improved
  • Clothes to fit better and look more flattering and feminine

Your height

Much like your build, your height can determine which size breast implants will best suit you.

Remember that if you’re looking towards others, for example celebrities, for inspiration, that their build, body shape, and height will differ from yours: what looks great and in proportion on them may not work best for you.

We always welcome you to tell us what you do and do not like about others; this is a great first step to take that helps your surgeon understand what you’re hoping to achieve.

Personal preference

And of course it goes without saying that one of the most important factors when choosing the right breast size is your own personal preference.

A good plastic surgeon will talk you through available sizes as well as their pros and cons, but at the end of the day, it is up to you to make a well-informed decision based on the information you’ve been told and what you want to see.

One of the first steps you should take when you begin considering the size of your breasts is to organise a consultation with Cairns Plastic Surgery.

Exciting developments in technology means we can actually create a mockup to show you what you might look like with your desired breast shape and size!

This 3D imaging technology is called Crisalix and we are so excited to bring this cutting edge simulation software to our patients. Find out more about Crisalix or book your complimentary nurse consultation here.

What kind of bra should I wear after breast augmentation surgery?

Immediately following surgery, you’ll be advised to wear a sports or surgical bra. This is a critical step is ensuring a safe and healthy recovery.

It’s also important you avoid underwire or push-up bras for a certain period of time following surgery, as your new breasts need time to naturally settle. These types of bras can affect recovery and the final shape of your breasts.

Your surgeon will provide you with all the information and guidance you need at your follow-up appointments. And remember, if you’re ever unsure, simply give our friendly team a call for immediate advice on (07) 4031 5755.
