How do I choose my breast implant size?

To choose your breast implant size, start with the look you want, compare different volumes, and discuss your preferences with your surgeon. These tools and steps can help you explore your options:

1. Breast implant sizers. Explore how added volume looks and feels on your own body, under your own clothes, during everyday activities—from getting dressed to exercising or spending time with friends. Trying different volumes gives you a practical way to compare your preferences beyond a quick look in the mirror.
2. Breast Implant Size Calculator. If you are unsure where to start, enter your current and desired cup sizes to get a broad educational estimate of volumes to explore with sizers. The calculator provides a starting point, not a surgical implant recommendation or a guaranteed cup size.
3. 3D imaging and online simulation apps. View simulated changes on screen to explore how different options may look and help explain your goals during your consultation.
4. Be informed. Our library of articles below is a good place to start. Search topics from breast implant sizes and bra cup sizes to trying sizers and preparing for your consultation. Understanding your options helps you ask specific questions and discuss what matters most to you with your surgeon.

Each method has limits: sizers sit outside the body and cannot predict your exact surgical result. Neither can simulations, and calculators cannot determine which implant is medically appropriate for you. Your surgeon can assess your anatomy and explain suitable options.

In one study of 341 women, nearly 1 in 4 said they would have preferred a different breast size three months after surgery. Read about the research. Our goal is to help you explore your preferences before surgery, so you can approach your decision feeling informed and confident.
