If you’re choosing to undergo breast augmentation, one of the most important parts of the journey is picking the right breast implant size. Your choice will influence not only how you look, but how you feel, move, and live with your new body over time. From breast implant comparison tools to real-world visualisation methods, there are many helpful strategies to guide your decision. At ICCM, we can assist you through every step of the process, ensuring your implant selection complements your body and aesthetic goals. This guide will walk you through everything you need to know–from breast size comparisons, size charts, lifestyle considerations, and more–to help you confidently choose your perfect implant size.

Understanding Breast Implant Sizes

When it comes to breast implant sizes, it’s important to know they aren’t measured by cup size, but rather in cubic centimetres (cc). This measurement reflects the volume of the implant, not its shape or how it will sit on your body. That’s why a 300cc implant can look dramatically different on two different people–it all comes down to your individual anatomy.

Typical Implant Size Ranges:

150cc to 250cc – A modest enhancement, often chosen for subtle, natural-looking results. 250cc to 400cc – A moderate increase, typically resulting in a one to two cup size change. 400cc+ – A more dramatic transformation, ideal for those seeking fuller volume and projection. But the cc number alone doesn’t tell the whole story. Factors like your chest width, existing breast tissue, skin elasticity, and placement of the implant (above or below the muscle) will impact how the implant appears once in place. In other words, implant size selection is more than picking a number–it’s about understanding how that number will look and feel on you.

There are a few aspects that you need to consider when it comes to choosing your breast implant size.

Breast Implant Comparison: Key Considerations

The process of breast implant comparison goes far beyond simply selecting the biggest or most popular size. To achieve a result that suits your needs, you need to evaluate multiple aspects of the implant:
  • Width (Base Diameter): This must match your chest dimensions to avoid side spillage or a too-narrow gap between breasts.
  • Projection: This refers to how far the implant protrudes from your chest wall. Options typically include moderate, high, and ultra-high projection, each offering a different look.
  • Shape: Round implants offer fullness throughout the breast, while anatomical (teardrop) implants provide a more natural slope.
  • Material: In Australia, silicone implants are the most common due to their realistic feel. Saline implants are less common but may be suitable in specific cases.
A thoughtful breast implant comparison will help you understand how these variables influence the overall appearance and feel of your breasts, making it easier to select an implant that suits your vision.

When choosing your breast implant size you’ll need to consider aspects such as activity level, personal goals and more.

Lifestyle & Personal Considerations When Choosing Breast Implants

Choosing your breast augmentation size is as much a lifestyle decision as it is a cosmetic one. It’s important to consider how your implant size will integrate with your daily activities, future plans, and personal comfort. Here are key things to reflect on:
  • Your activity level: Highly active individuals–especially runners, dancers, or gym-goers–may prefer smaller or moderate implant sizes for ease of movement and long-term comfort.
  • Clothing and body proportions: Consider how implants will affect the fit of your current wardrobe and how they will balance with your hips, waist, and shoulders. A well-chosen implant enhances your silhouette–not overwhelms it.
  • Long-term changes: Think ahead. Pregnancy, ageing, and weight fluctuations can alter breast appearance over time, so it’s helpful to choose an implant that will still feel right for you in five or ten years.
  • Personal goals: Are you looking for a natural enhancement that feels subtle, or are you aiming for dramatic volume and fullness? Clarifying your end goal helps your surgeon guide the decision-making process.

FAQs

How are breast implant sizes measured and what do the numbers mean?

Breast implant sizes are measured in cc (cubic centimetres). The higher the cc, the more volume the implant provides. For example, 250cc may provide a subtle increase, while 400cc+ will offer more dramatic results. The same cc can look different on different body types.

How do I know which size is right for me?

Your ideal size depends on your frame, chest width, existing tissue, and personal preferences. A combination of clinical measurements, ideal implant size chart references, and trial sizers during consultation helps you and your surgeon reach a comfortable decision.

Can larger implants still look natural?

Yes, breast implants sizes in the higher range (400cc+) can still look natural when chosen appropriately for your body and paired with the right shape and placement. ICCM’s team helps ensure the final look is proportionate and balanced.

Will my lifestyle affect the implant size I should choose?

Absolutely. Active individuals often choose smaller or moderate breast augmentation sizes for comfort. If you plan to become pregnant or experience weight changes, these can also influence how your implants look over time.

What if I choose an implant size and change my mind later?

It’s completely normal to have second thoughts, which is why the consultation process is so important. At ICCM, your surgeon will work closely with you to help you feel confident in your choice before surgery. If you’re still unsure, you can take additional time or schedule a follow-up consultation. Changing implant size after surgery is possible but involves another procedure, so it’s best to get it right the first time.

Do breast implants come in different shapes, or just sizes?

Yes, breast implants vary in both size and shape. The most common shapes are round and anatomical (teardrop). Round implants provide fullness across the entire breast, particularly at the top, while anatomical implants mimic the natural slope of the breast. Your surgeon will help determine the most suitable shape based on your anatomy, aesthetic preferences, and how the implant size will sit within your chest dimensions.
