How to Use This Calculator

This tool helps you estimate your post-augmentation bra size based on implant volume and your current measurements:

  1. Enter your desired implant volume in CCs (cubic centimeters), which is how breast implants are measured.
  2. Select your current band size (the number in your bra size, e.g., 34).
  3. Choose your current cup size (the letter in your bra size, e.g., B).
  4. Click "Calculate" to see your estimated post-surgery bra size.

Remember that this calculator provides an approximation. Many factors influence your final result, including your body frame, chest width, and the implant profile your surgeon recommends.

Frequently Asked Questions

How many CCs equal a bra cup size?

Roughly 150–200cc = one cup size, but it varies by body type and band size.

Does band size affect cup size appearance?

Yes. A 300cc implant looks much larger on a 32-band than a 38-band frame.

Are implant shapes and profiles considered?

This tool provides estimates for round, moderate-profile implants. Results may vary with ultra-high or anatomical implants.

What if I already had implants before?

Input your total CC volume. If you're replacing, subtract the old volume from the new.

Is this calculator accurate for every body?

It's an estimate only. Bra sizing is imprecise even across manufacturers. Always consult your surgeon for fitting guidance.
