Your breast enhancement is an exciting journey, and Dr. Michele Koo is here to help you every step of the way. Choosing the ideal breast implant size is a pivotal and very personal decision, and Dr. Koo aims to make it a positive and empowering experience. We understand that achieving the results you desire, while ensuring a comfortable and natural fit, is so important. In this blog, we’ll explore your options and provide a useful breast implant size chart to help you find your perfect fit.

Understanding breast implant sizes

Breast implants come in a great range of sizes, measured in cubic centimeters (cc). The size of the implant directly influences your final cup size and the overall appearance of your breasts. Cup sizes, on the other hand, are more commonly recognized and range from AA to DD and beyond. Understanding the harmony between these two measurements is key when selecting your dream breast implant size.

Small, medium and large: What’s the difference?

What is considered a small breast implant?

When it comes to small breast implants, you’re looking at a subtle, natural enhancement that typically ranges from 100 cc to 300 cc. This choice is perfect for those of you who seek a modest change, providing a confidence boost while maintaining a harmonious look. You may simply want to replace the fullness and roundedness of your breasts before pregnancy or breastfeeding. You may simply want to replace the firmness of your breasts before weight loss or hormonal changes.

What is considered a medium breast implant?

A medium breast implant, usually ranging from around 300 cc to 450 cc, offers a noticeable yet natural enhancement. It’s the preferred choice for individuals looking to add or return fullness and proportion, resulting in a balanced and confident appearance.

What’s considered a large breast implant?

For those considering large breast implants, typically 450 cc and beyond, you’re stepping into a category that offers a more dramatic transformation. Whether it’s for a curvier figure or to restore lost volume, these implants, when carefully selected, can provide a striking yet natural change that aligns with your individual preferences and goals. A larger implant may be perfect for a tall, lengthy torso or take up the slack of extra breast skin.

What is the most common breast implant size?

The most common breast implant size usually falls in the range of 300 cc to 400 cc, offering a noticeable yet natural enhancement, resulting in an increase of approximately 1 1/2 to 2 cup sizes. This size choice provides a balanced and harmonious appearance without an overly ‘in your face’ dramatic change! However, finding the perfect fit for your unique goals is essential.

Selecting the right implant size

Selecting the appropriate breast implant size involves careful consideration of your desired results and your body. Here are some essential steps to help you make an informed decision:

Consult with a Board-Certified Plastic Surgeon: A consultation with an experienced plastic surgeon is the first step. They will assess your body type, discuss your goals, and recommend implant sizes based on your unique circumstances.

Dream Big, Dream Beautiful: Be crystal clear about the look you want to achieve. Whether it’s a subtle enhancement or a more dramatic transformation, YOUR VISION matters!

Think About Proportion: Your chosen implant size should beautifully complement your body’s proportions. What suits one person may not be the right fit for another.

Discuss Implant Types: In addition to size, breast implant type plays a role in the final result. Discuss options like saline, and silicone and their specific projection height to circumference ratio and their suitability for your breasts and rib cage with your plastic surgeon.

Consider Your Lifestyle: Think about your daily activities, fitness routine, and clothing choices. Your implant size should complement your lifestyle and what you want to wear, and your comfort level and desire to show cleavage. Your profession may be a significant factor in the choice of your type and size of breast implant.

Trust the Expertise: Your plastic surgeon is your trusted partner on this journey. They will provide expert guidance, considering your goals and anatomy and guide you to the perfect breast implants. It is extremely important you are on the same visual page. Dr. Koo always recommend bringing pictures of your ‘perfect world’ breasts to the consultation in addition to discussing your preferred ultimate cup size.
