Breast augmentation can change your life for the better. The procedure can improve your self-esteem and allow you to create the body you’ve always wanted.

Like all the best things in life, it’s not entirely straightforward. Deciding to have implants fitted takes a lot of courage, determination and consideration. While the material, shape and placement of your breast implants have a massive effect on the outcome of your boob job, for most women, it’s the size that counts.


Choosing the right breast implant size is impossible without an in-person consultation with your surgeon. Every woman’s body is different, so Mr Pieri offers an extensive sizing consultation prior to the procedure and the opportunity for women to take the time they need to find the perfect fit. 


As an introduction, this breast implant size guide aims to help you understand how your plastic and reconstruction surgeon can help you find the best breast implant sizes.

How Do We Measure Breast Implants?

There are three units of measurement for breast implants: implant volume, diameter and profile. Each term refers to different ways to measure implants, and all are relevant when deciding on the right size for you.

Implant Volume

Volume is the factor most patients focus on, but Mr Pieri believes that all are equally important. It’s the combination of all three that helps him to find the perfect implant sizes for your body.

This unit of measurement refers to the amount of space the implant will take up and is measured in cubic centimetres (CC). Implants usually vary by 10-20 CC, with the full range spanning between 100- 1000 CC. The most common breast implant sizes range from 300- 400 CC.

Implant Diameter
Diameter, or base diameter, refers to the width of the breast implant you’re getting and is measured across the bottom of the implant from side to side.

For round implants, the diameter will be the same across most of the surface, while for teardrop implants, the base diameter is the largest section. The diameter of the breast implant affects the fit and your post-procedure breast width.

Implant Profile

Profile refers to how far off the chest your implant will project from your chest wall, meaning it directly correlates with how big your breasts will seem.

The main types of implant profile are:

  • Low Profile: Smaller implants that project less from the body, giving a more natural look. Ideal for women with broad chests or those looking for a smaller lift.

  • Moderate Profile: Medium implants that offer additional fullness. Ideal for women looking for larger breasts without a dramatic change.

  • High Profile: Larger implants that protrude significantly from the chest. Ideal for women who want a noticeably bigger chest.

Within these three categories, there are various profile gradients, allowing you to find the exact right size for your implants.


As part of your first in-person consultation with Mr Pieri, he will discuss all of these measurements to help you pick the right breast implant size.

Breast Implant Size Calculator

When you’re discussing your breast augmentation, your surgeon will recommend a breast implant size in CC, which might not align with the way you think about boob sizes.
That’s because the cup sizes on the bras you buy in shops aren’t accurate. They’re not standardised, so some brands might have a slightly different way of measuring breasts.
As CC is a unit of measurement, it’s universal and used by most breast surgeons globally.
So, working out the right breast implant size for you requires an understanding of how implant volume in CC compares to the bra cup sizes in shops.

This table acts as an approximate guide- please be aware that as bra cup size is not a universal measurement, we cannot guarantee these results, but this should offer a rough estimation. 
Breast Implant VolumePotential Increase In Bra Cup Size (Approx)
150- 170 CCA – B Cup
300 – 350 CCA – C Cup
370 – 430 CCA – D Cup
150- 170 CCB – C Cup
300- 400 CCB – D Cup
500- 600 CCB – DD Cup
200-250 CCC – D Cup
400- 450 CCC – DD Cup
600 – 650 CCC – E Cup
200- 300 CCD – DD Cup
450 – 600 CCD – E Cup

What Are The Most Popular Breast Implant Sizes? 

The most common breast implant size is between 300- 400 CC, but the best option for you depends on what you want to achieve.

Bringing photos to your initial consultation will help give Mr Pieri an understanding of what size you’ll need. However, it’s important to remember that your shoulder width, rib cage shape, torso length and other factors will play a part in how big your implants need to be.

So, if you already have a size in mind, don’t be surprised if Mr Pieri suggests a different option based on his expertise and measurements. He can help you select an implant that will match your desired outcome.

Does The Size Of Your Breast Implants Affect The Cost?

The size you choose won’t affect the cost of your procedure, as the price of the implants is a flat fee, no matter what the size. Your surgeon’s time and expertise are the main factors influencing the price you pay, not the size of your implants.

As such, this is one of the few factors that won’t affect the cost of your breast augmentation procedure.

What Should You Consider When Choosing A Breast Implant Size? 

 Every woman is different, and your unique circumstances, motivations and preferences will greatly impact the breast implants you need.
For example, a woman trying to create curves will look for larger breast implants. On the other hand, someone who is trying to reverse slightly sagging breasts and add volume might need smaller breast implants to achieve their goal.
So, when selecting the right breast implant size, you need to consider:
  • Lifestyle: Factors such as how much exercise you do will significantly influence your breast implants. Active women might want to opt for smaller breast implants, as these can give you a perkier look without being obstructive during workouts.

  • Body Type: Getting the right appearance from your implants means ensuring they fit your body shape. Women with broad shoulders, taller women and those with wide hips suit larger breasts. Anyone with a petite frame and narrow shoulders or waists will look out of proportion with a very large chest, so smaller breast implants are a better choice.

  • Implant Material: All breast implant shells are made from silicone in the UK, but the material inside can change the overall effect. Saline implants are typically harder than their gel counterparts, so they can give a more rigid look and appear larger. Silicone breast implants containing gel are softer, more natural and often less likely to rupture, making them popular with most women.

  • Future Plans: If you’re considering having children in the coming years, you need to think about the changes your body will go through during this time and how breast implants might affect pregnancy. Breastfeeding a baby with breast implants is possible. However, a larger implant may impact the milk ducts and cause problems, so choosing from the smallest breast implant sizes is recommended.

Each of these factors will affect the size of breast implants that work best for you, so be honest with yourself and figure out what you want when preparing for your consultation. Mr Pieri won’t judge, but without accurate information, he can’t give you the right suggestions and support throughout the breast implant process.

How Mr Pieri Can Help You Choose The Right CC 

 Having practised breast enlargement in Newcastle for over 16 years, Mr Pieri understands the difficulty many women have when selecting a breast implant size.
During his initial consultation, he will explain:
  • How the breast augmentation process works

  • The best ways to achieve your desired look

Mr Pieri won’t get you to commit to an exact size: you’ll select an implant within 50 CC of your desired look, and he will make adjustments during the procedure to ensure you get the outcome you want.

When the consultation is complete, you’ll have the opportunity to go away and think about your decision and have a follow-up session to answer any questions about the process or recovery

Can You Change Your Mind Once The Implants Are In? 

Whether you need breast implants for medical reasons, such as breast reconstruction after a mastectomy, to address age-related volume loss, or to get your desired look, the size you choose will make a difference to your comfort level and appearance.
If you’re unsure right before the procedure, then Mr Pieri will provide you with an additional sizing session to help you feel comfortable with your choice. You can take as long as you need to decide on the right breast implant size.

By following this process, you should be able to get the right breast implant size and achieve the outcome you were hoping for. In the future, if you want to change your look again, you can speak to Mr Pieri about the best way to go about this.
