If you long for sexier upper body curves or more noticeable cleavage in swimwear, low cut fashions or lingerie, it’s helpful to learn the PROS and CONS of different breast implant surgery.

One big decision you’ll make about getting bigger breasts is which implant SIZE – and type – to choose.

  • Size matters or you wouldn’t be thinking of an augmentation.
  • But how large should you go when you’re investigating breast implants?

Choosing a “glamorously enhanced” look versus a “more natural-looking” Breast Augmentation – discuss this with your Surgeon, who has years of experience helping women assess what size and type of breast implant will suit their body – and skin health – best.

But how do you know what breast implant to choose? This is where 3D imaging and bra sizers are effective tools for planning your breast operation.

  • When you’re deciding between small breast implants vs large breast implants, you’ll want to understand the many factors that can influence results.
  • A good Surgeon will take these factors into account when helping you decide which breast implant sizes are best for your procedure. 
  • There’s the glamorous looking larger breast implant operation and there’s the mini boob job – and everything in between!

Background: Although Breast Augmentation surgery is commonly performed in Australia and around the world, this does NOT mean breast enlargement is a simple operation. Neither is breast augmentation surgery guaranteed to get you a good result. Like other forms of cosmetic surgery, getting good results requires precision planning and high-level surgical skills, as well as extensive experience. Selecting the right breast implant size/shape to suit your body, then, is both “an art” as well as “a science” involving measurements and calculations.


The AIM of Breast Augmentation surgery is to get an aesthetically pleasing result (visually), that is also long-lasting and less prone to complications such as premature sagging.

To achieve this breast augmentation surgery goal, a number of factors need to be taken into account.

  • A top Breast Augmentation surgeon will want to understand your lifestyle as well as your surgery goals and existing proportions.
  • Additionally, your personal ideal for a breast shape or size increase needs to be discussed.
  • This is to ensure you have realistic expectations of what can be achieved through breast surgery; which is somewhat dictated by your existing body shape, skin and breast tissues.

Be sure your Surgeon understands your motivations and goals for seeking breast implant surgery. It’s best to work together with your Specialist Plastic Surgeon, as a team, to consider what implant size or shape you’ll be pleased with after having surgery.

Here’s what Melbourne Specialist Plastic Surgeons consider when collaborating with you in relation to your implant size choices during your Consultation.

  • Our Specialists will evaluate your existing breast tissue or breast composition and your breast crease (the inframammary crease).
  • They will also assess where the breasts sit on the rib cage (distance from the shoulders/neck area), the height of your torso, and your overall height and weight (we have a high-tech BMI machine that is helpful in this regard).

Getting this information helps to evaluate your potential results and may be used to track changes to your body composition over time, such as weight fluctuations, which can impact your results over time.

  • Our Surgeons will also measure where your nipple-areola complex sits to help identify if there’s an extremely noticeable asymmetry in your breast size, breast mound shape, or nipple locations.
  • They will also evaluate the condition of your skin’s strength (firmness, thickness or resiliency) to assess whether the edges of the breast implant are likely to be seen and felt or cause rippling.
    • Having SOME existing breast tissue and adequate body fat can often help in this regard.
    • Yet many thin women seek breast implants, so the prosthesis size, insertion pocket and implant placement are KEYS to getting a pleasing result.
    • There’s even the potential for fat transfer to the breasts to slightly enhance the shape when deemed appropriate, but this is another surgery and can add to the complexity of the procedure (fat grafting is typically NOT required for augmentations).

SURGERY PLANNING TIP: During your consultation, you’ll also want to discuss your lifestyle and how having larger breasts will influence your day-to-day activities including exercise, sports and fashion choices.

  • Bra Sizers and 3D Vectra Imaging may also be used to help you envision the balanced proportions of larger breasts.
  • These breast implant selection steps are part of how excellent Breast Augmentation Surgeons can help you choose a suitable breast implant size for your body and your lifestyle.
  • A good Surgeon will take all of these factors into account to help you decide, but it is also up to you and your preferred appearance goals.
  • If you’re about to have Surgery – or merely doing more breast augmentation research – read on to understand the PROS and CONS of different breast implant sizes.

Natural Looking Surgery Results versus the Obviously Enhanced “Gold Coast” Glamorous Appearance.

What should you consider in terms of size?

  • Depending on your body proportions, your skin health and your existing breast tissues, you may be choosing between a “natural-looking” breast augmentation or a noticeably enhanced appearance when planning for surgery.
  • What size suits your body is largely dependent on what you’re starting with to begin with, as well as what you’re aiming for in terms of appearance.
  • If you have a certain lifestyle or profession that is somewhat impacted by your breast appearance, such as swimwear modelling, dancing, or working as an escort.

When it comes to choosing between small breast implants or large breast implants, it can help to have an idea of what you’d like your upper half to look like; but DO recognise your choices MAY be limited by your existing body proportions and your skin health.

  • If you go for a very large implant (as shown in the image above), it can easily look out of balance on your body.
  • What looks great on one person might look awkward on your own body; this is where size assessment tools are valuable.
  • And if you go larger than suits your physique when you have a relatively short torso, the breast implants can end up hiding your waistline and leave you looking frumpy. It’s as if you’ve gained weight all over instead of just on top, so DO take into consideration the overall effect of having larger breasts, side boobs and cleavage.

Choosing the right breast implant size is paramount – no matter what your height. Your rib cage, chest size, torso proportions and your body mass index (BMI) all need to be factored into your surgery decisions.

Questions to ask yourself about Breast Enlargement Surgery before choosing an implant size:

  • Are you wanting a much fuller look or just a bit more ‘sideboob’ and upper-pole cleavage?
  • Do you want to balance out the top half of your body?
  • How are you going about the process of selecting your ideal Breast Augmentation bra cup size?
  • Are you wondering about whether to go for a natural-looking result or a  ‘glamorous’ style breast enlargement (a more obviously ‘enhanced’ look or “Gold Coast” appearance)?

It’s helpful to understand the factors involved in choosing the right breast implant size to suit your body, including your proportions.

  • What is your height?
  • Are your hips narrow or wide; and how long is your torso?
  • What shape is your rib cage, and how far apart are your nipples?
  • Are your nipples roughly located in the same place on each breast?
  • Is your skin firm and tight, and do you have any pre-existing tissue that will help cover an implant?
  • Or is your skin sagging and droopy, such as can happen after weight loss? (You might need a breast lift and/or a breast lift with an implant if you have sagging skin after pregnancy or weight loss)

Our top Melbourne Surgeons use several methods for assessing a good breast implant size versus an inappropriate size selection.

  • They take numerous measurements as well as assess your skin strength and body proportions.
  • They’ll discuss the look you’re wanting to achieve, and what’s possible via surgery. so you can feel better about your size choices.
  • Schedule a no-obligation surgery consultation or ask about breast implant sizing options by phoning us on 1300 264 811

Small Breast Implants vs Large Breast Implants: Breast Implant Size is relative.


Choosing the best-sized implants really depends on your physique as well as your ideals. Here are our Tips.

  • Think LONG TERM:  Many factors impact how the result appears not only just after surgery but over the years that follow. Consider what you want to look like in 5 to 10 years (and you may need revision surgery or removal and replacement in the future).
  • Ask your SURGEON for help: Choosing the right size and profile of your breast implants is definitely one of the more challenging decisions you’ll make before surgery.
  • Think CUSTOMISATION not COOKIE CUTTER: There is NOT a one-size-fits-all option, and good results require thoughtful customisation.
  • You may initially think you want a noticeable breast enlargement. And for some women, this makes a lot of sense.
  • But once you understand the PROS and CONS of smaller breast implants vs larger breast implants, you will likely PREFER a size that leaves you with a balanced chest and body appearance.

You could have problems if you choose a breast implant size that is too large for your physique or skin health.

  • The bigger or heavier the implant, the more likely your skin may become prematurely stretched or droopy.
  • The breasts may sag or droop or ‘bottom out’.
  • They may look noticeably ‘fake’ or ‘over the top’ and out of balance with your physique.
  • You may find it difficult to participate in sports and other activities.
  • Your breasts may become the focus of unwanted attention OR cause shoulder or back pain if they are overly heavy (which is why so many women with naturally large breasts choose Breast Reduction Surgery).

There are other factors to consider when you’re leaning towards very noticeable augmentation results (large breast implants) vs smaller “natural looking” implant sizes.

One factor relates to the day to day practicality of living with larger breasts.

Key questions to ask yourself before settling on an “ideal” breast size goal  might include:

  • What’s my lifestyle like?
  • What types of exercising do I regularly engage in?
  • Will having significantly larger breasts impact my ability to jog or compete in sports?
  • Will I be comfortable with breasts that enter the room before I do (figuratively speaking), or do I want people to think I’m naturally enhanced?
  • Do I have a profession where having highly glamorous cleavage is an asset, or would it potentially be a distraction?
  • Will having large breasts dictate what clothing and necklines I’ll feel comfortable wearing?
  • Will I have to buy mismatched sizes of bathers if I’m buying a bikini? (Fortunately, however, this is easily done as many women have different sized upper and lower bodies when it comes to fashion sizes).
  • How soon do I want to have children and if I do have children, will I try to breastfeed?
    • Big implants may make it difficult to breastfeed
    • As with any breast surgery, sometimes the ability to breastfeed MAY be impacted by surgery; that noted, many of our patients have successfully breastfed after breast surgery including breast lift, breast augmentation, and breast reduction surgery, and our surgeons take great care to NOT disturb the milk ducts.
  • Will my posture be impacted by the degree of augmentation?
  • Will finding a bra that fits comfortably be difficult if I choose a larger breast implant size?
    • It’s imperative you wear a good support bra after ANY breast surgery to help maintain your results
    • Going bra-less is a NO-NO!

In Summary, these are the key items to consider when choosing the breast augmentation prosthesis (breast implant sizes):

  • Whether a natural-looking vs noticeably enhanced breast augmentation look is going to meet your goals – AND match your overall physique.
  • Whether your skin health suits larger breast implants or smaller breast implants.
  • How much sagging there is in the breast skin area; and whether a particular sized breast implant will worsen the skin sagging or help fill out the breast tissues – and how long these results might last.
  • What impact having larger breasts and cleavage will have on your overall body shape and clothing choices.

The longevity of your results is also a key consideration when it comes to choosing small breast implants vs large breast implants.

Sure, you might want a lot of cleavage, but how much is too much – and how long will a larger size last?

  • Silicone breast implants come in numerous sizes and several different shapes (there are also saline implants although they are not as popular).
  • We use proven, quality silicone implants including Mentor breast implants (we don’t use cheap, lesser-known or inferior implant brands – and we suggest you watch out for Doctors who offer cheap augmentation by cutting costs or using NON-specialists to perform cosmetic plastic surgery).
  • Implant sizes can range from small (in the 100 cc to 250 cc range) to large (over 400 cc) to very large (over 600 cc).
  • There isn’t, per se, an average size that will look great on most bodies.
  • It’s best to select the size to match the person, the body frame and torso size, the existing breast tissues and skin capacity, and the desired cleavage goals.

There are popular ranges that many women choose from, but choices depend on how much the person weighs, how short or tall they are, how short or long their torso is, the width of their chest/rib cage, and how far below the shoulders the breasts and nipples are located – as well as the resiliency of their skin.

Large implants may show more in smaller, thinner women or women with less natural breast tissues.

Breast implants are often placed partially beneath the muscle to be less noticeable. For many breast surgeries, however, you can’t always tell if a woman has chosen enhancement surgery (or not). But your body mass index AND your skin health may limit your breast implant size choices.

Many, but not all, women who choose breast augmentation surgery to have a physique leading to naturally small breasts or underdeveloped breasts (perhaps low body fat or a thin physique, or a condition such as tuberous breasts).

This may mean that a small breast implant is your best choice; so that the edges of the implant are less visible, and that your skin can more readily accommodate the breast size enhancement.

  • You may find out that if your breast implants are overly large, your surgery results might not last as long.
  • They might look great to start with, but end up sagging or otherwise not LOOKING as good as you hoped.
  • They might be more prone to complications such as rippling, ‘bottoming out’ or premature sagging.
  • If you have sagging skin after pregnancy or after losing weight, you may need a mastopexy-augmentation (a combined breast lift with implants) to get the results you’re seeking with augmentation surgery – OR to better enable the breast skin to accept and firmly hold your implant.

Do breast implants make you look like you gained weight?

  • If you choose large implants, and if you have a relatively short torso, your body might end up looking ‘plumper’ than before you had breast augmentation surgery.
  • Whereas a smaller implant might give you a more balanced upper-and-lower-body physique without the risk of looking suddenly pudgy when you’ve not actually gained additional weight.

The right Specialist Plastic Surgeon can help you understand the pros and cons of different breast implant size choices and whether or not you’re best off with small breast implants vs large breast implants, or the other way around.

When you come to see one of our Specialist Plastic Surgeons in Melbourne for an opinion by a genuine Specialist Plastic Surgeon, you’ll get honest and helpful advice about implant size choices.  You can even request a VECTRA 3D imaging session (ask about this when you phone 1300 264 811

  • Our Surgeons will explain how different sized breast implants will impact not only your breast cleavage but your overall body proportions and entire physique.
  • They will help you choose the right size by taking numerous physique measurements, using bra cup sizers, and discussing the pros and cons of different implant choices in relation to YOUR specific physique, skin health and appearance goals.

This is helpful information to have as you explore your options for breast enlargement surgery. Because NOT all breast implants will suit all women, and your overall physique impacts your results.

  • It’s also important to understand that weight fluctuation occurring over time – and life events such as having a baby or breastfeeding – are all likely to impact your results.
  • Remember, breast implants have a stated life span of around 10 years. Get the most from your Surgery by choosing wisely.
  • This also means you will require future surgery at some stage, after having breast augmentation surgery.
  • It might be a breast lift/nipple lift and/or removal and replacement or revision breast surgery, but DO expect a future operation at some stage in time.

You’ll likely want to get the longest life out of your breast enhancement surgery. So it makes sense to stay reasonable when choosing breast implants to increase your cup size.

Small Breast Implants vs Large Breast Implants During Breast Enlargement Surgery

The Pros and Cons of Breast Implant Size

Watch out for the ‘one size fits all’ approach or ‘cookie-cutter’ style cheap production line surgery outfits.

There are, sadly, Surgeons who will just give a patient whatever implant size they request, regardless of the patient’s long term prospects for getting a pleasing, lasting and good looking breast augmentation result. Whilst this may sound good to someone on first impressions, the sad news is that the patient may not enjoy their surgery for as long as they might if the right implant size was chosen.

  • Watch out for fluctuations in weight over time, and understand how this will impact your results.
  • Stay fit and healthy and eat nutritiously to improve your chances of having a long-lasting, aesthetically pleasing result.
  • Watch out for any signs of needing a revision breast surgery and/or breast implant removal and replacement.

Occasionally you’ll have difficulty with implant surgery, and it is likely this may be the case if you choose to go larger than your body can readily sustain. Other things to watch out for include ‘bottoming out‘ or if the breast area goes hard or feels constricted in a painful way.

  • If you follow pre-surgery and post-surgery care advice, including never smoking, eating well and always wearing a bra, AND
  • You choose a genuine Plastic Surgeon who can assist you in making a good choice about your breast implant size AND
  • You choose an implant size that has the best chance of getting a pleasing result that also has good longevity

Then you, too, may gain the cleavage, fullness and sexy upper body curves you’ve always wanted.

The Downside of Bigger Breast Implant Size

1. Gravity and Breast Implant Size

Over time, the larger your natural breasts are, the greater the fall. How does this affect those who have breast implants? It depends on the size of the implants and your body frame size.

For example, if you are very petite, a breast implant larger than 200 cc could be too large for your body. Generally speaking, a breast implant higher than 350 cc is always considered large. The range of breast implant sizes is 150 cc to over 700 cc.

Your surgeon will help you decide what size will be best for you.

Your Melbourne Plastic Surgeon may make breast implant size recommendations based on several factors (but it is up to you to decide).

breast implant sagging - best breast implant size to choose for breast lift mastopexy augmentation

Factors that relate to which breast implant might be best for you for your breast augmentation goals include:

  • the amount of natural breast tissue you have
  • your measurements (chest and rib cage)
  • how much space is between your nipples
  • how much the breasts droop
  • your overall proportions
  • if your breasts are symmetrical or not
  • where the implants are placed – either under the muscle, above it, or dual-plane
  • Thus, the larger your implants, the greater the fall.

You may still want to have a large implant for very large breasts as part of your breast augmentation, and you may be happy with a less natural look or with the sagging risk.  Not all surgeons, however, will agree to use a very large implant if they feel the long term result won’t be sustainable or pleasing for you or if there are other reasons not to pursue surgery.  So ask your Specialist Breast Surgeon what they recommend and why they are recommending that particular breast implant size for you.  You can also try VECTRA 3D imaging or sizers to get a sense of the increase BEFORE you agree to a certain breast implant size.

2. Breast Implants Add Weight to Your Body and Thus Accelerate the Fall

How much do breast implants weigh?

  • Implants are lightweight, in general, but they still add weight to your body.
  • If you’re like most patients, you will notice the volume increase and cleavage enhancement after surgery.
  • But you won’t tend to feel the added weight once they’ve been inserted in the chest area as much as you might when you simply hold one in your hand.
  • However, a 650 cc breast implant may mean your chest wall and breast tissues (breast skin) have to support an extra 1.3 kilograms.

Not only is that size and weight potentially likely to be uncomfortable for women with minimal breast skin, but that’s also quite a bit of a fall when it happens.  So choose your implant size carefully and keep time, breast skin and gravity in mind.

3. Movement Accelerates Ageing of Tissues That Lose Elasticity

  • While you move around during the day or are walking and running, gravity is working against the implants staying in position.
  • Gravity forces bring the implants and your own natural breast tissue away from your chest.
  • There’s a greater force if the implants are larger.

4. Ageing and Elasticity of the Skin Are Considered When Choosing Which Type of Breast Augmentation to Get

why is my breast implant agging after augmentation surgery
  • Your skin naturally loses its own elasticity and lacks firmness over time.
  • There’s an enzyme called collagenase that will break down collagen, and its levels are higher when you are in your 40s and 50s.
  • In your 60s, even more collagen is broken down.
  • Many women get breast implants for the first time in their 40s, 50s and even 60s.
  • For women over 30, choice of breast implant size and surgery procedure often depends partially on the skin quality and condition of the breast tissues
  • Your surgeon considers what he or she believes your breast skin will best support when helping you choose your implant size or type of breast enlargement surgery (mastopexy augmentation, or breast augmentation as a stand-alone procedure).

The larger your implant, the more your skin stretches and the more it might lose additional elasticity over time.

But whichever size implant you choose, you’ll want to be sure you wear high-quality supportive sports bras at all times to increase the longevity of your results.

5. Personal Habits Affect Skin Changes Over Time

  • Smoking will accelerate any gravity changes in your body and leads to premature ageing of the skin and organs.
  • Smoking causes a deficiency of vitamin C in the body and impacts your body’s ability to absorb many nutrients.
  • Vitamin C is a primary nutrient that works against ageing effects.
