How to Choose the Right Breast Implant Size for Your Frame
Published by Mr. Banwell
Maybe you have been thinking about having a breast augmentation for a while now. Not because you want to change the way you look, but because you want to feel more like you.
One of the biggest decisions to make is finding the right breast implant size for you.
Many patients feel anxious about them being “too big” or “too small” or not achieving the desired aesthetic outcome they are hoping for.
Plus, there’s so many factors to think about such as implant volume, breast implant profiles, what existing breast tissue you have, and your body shape.
It’s no wonder the process can feel overwhelming at first.
So, how do you choose the right breast implant size for your frame? With Mr Paul Banwell, you do not have to do it alone.
He will walk you through your options, explain what will work for your body type, and help you feel more confident in selecting an implant size that gives you balanced results.
For personalised breast augmentation advice, you can also book an initial consultation with Mr Banwell.
Breast implant sizing – what you need to know
Firstly, in case you did not already know, breast implants are measured in cubic centimetres (cc) – not bra cup size.
Secondly, breast implant size does not just come down to picking small, medium or large, it is much more nuanced than that.
There are many factors that a plastic surgeon will use to help find the right implant size, including:
- Implant volume,
- Implant profile
- Breast volume
- Existing breast tissue
- Body frame
- Chest width
- Chest wall shape
- Shoulder width
The idea of the perfect breast size does not exist.
What matters most is choosing an implant size that suits your body type, understanding how it works with your natural breast tissue, and feeling confident you will see natural results.
We find that most patients do not always realise that size and shape work together.
For example, choosing round implants can help create more fullness. While different breast implant profiles (low, moderate and high) will impact how fat your implant will project forward from the chest wall.
What are the most popular breast implant sizes?
This is a question we get asked all the time. But the truth is, there is no single common breast implant size that will work for every woman.
Most patients choose breast implants between 250cc and 400cc. This range of sizes tends to complement a wider range of body shapes and body types.
But size will also depend on whether you want a subtle enhancement or a more noticeable result.
The most common breast implant size categories
- Small – 150cc to 250cc for a subtle change and women with a petite frame
- Medium – 250cc to 350cc for noticeable fullness
- Large – 350 cc plus for a larger frame as it creates a more dramatic result
Smaller implants or a ballerina breast augmentation, tend to suit women who have a slim or athletic frame.
Whereas women with larger frames or more tissue coverage may be able to accommodate larger breast implants.
Many patients start with a breast implant size calculator. This can be a good jumping off point to think about which implant size may suit you, but it should not take the place of a consultation with a plastic surgeon.
Understanding your body shape
Your body shape or body frame is one of the most important factors to consider when thinking about breast implant sizes.
For example:
- A petite or slender frame may achieve more balanced results with smaller breast implants.
- Someone with a wider chest width may need a larger implant or a different profile to ensure the results are symmetrical.
- If you have thin breast tissue, it can limit how much breast tissue can safely cover the implants. This can influence the profile of the implant you need.
If you are unsure about your body shape or body type, Mr Banwell can talk you through this during your consultation, along with the different implant sizes that might work best.
Why you should not base implant size on bra sizes or cup sizes
Have you ever tried a bra on in two different shops, only to find that your size is not your size in the next shop? This is because bra sizes vary between different brands.
Your cup size is not a reliable way to measure what implants you need or what the outcomes of your breast implant surgery will look like.
Breast implants are measured in cc, not bra cup size. This is because cc gives you a more precise measurement of implant volume.
Never compare yourself to others, as two women with the same bra size can have completely different breast volumes, chest widths and natural tissue.
This is why boob job sizes should always be based on your anatomical proportion rather than a target bra size.
What are the different types of breast implants?
A good starting point for anyone thinking about breast augmentation surgery is to understand that implants do not just vary in size, but also in shape, profile and material.
All these factors will work together to help create your final look.
Many patients decide to opt for silicone implants because they tend to be much closer to the feel of natural breast tissue.
Silicone breast implants come in different profiles:
Low profile implants
These implants cover a larger surface area of the chest wall. They work best for those who want a subtle enhancement and only minor volume changes.
Moderate profile implants
Moderate profile breast implants project a medium distance from the chest wall. They also spread the volume more evenly for a gentle and more natural slope.
High profile implants
Have a much more narrow base. They extend outwards more than low and moderate profiles. High profile implants also create more upper fullness and a defined cleavage.
Silicone gel implants – Motiva and Mentor
Mr Paul Banwell uses two of the most trusted and advanced types of implants – Motiva and Mentor.
Both brands of silicone implants offer a wide choice of implant profiles, shapes and sizes. This makes it easier to tailor your breast enlargement to your desired result.
Motiva implants
Patients tend to choose Motiva breast implants because they have a smooth feel and offer natural movement. They also blend seamlessly with your natural breast tissue. This makes them ideal for women with thin breast tissue or a petite body shape.
Mentor implants
Mentor breast implants are known for their reliability and wide selection of volumes and shapes. They can support a subtle enhancement with small implants or fuller results with larger implants.
Mr Banwell will talk you through both types of implants to decide which will help create a balanced, natural look that will suit your body type.
Consider your lifestyle and hobbies
This point is often overlooked by many patients, but it is actually more important than you think.
If you love doing yoga, running or spending time at the gym, you may want to think about smaller implants with more natural movement. This ensures you can keep up with your active lifestyle while still feeling comfortable.
If this is you, or you want to achieve a more refined and subtle enhancement, you may want to opt for a ballerina breast augmentation with Mr Banwell.
