How to Choose the Right Breast Implant Size

By Assoc. Prof. Dr. Ayhan Işık Erdal, MD, FACS, FEBOPRAS · Updated April 2026

Choosing the right breast implant size is one of the most important decisions in breast augmentation. The ideal implant is not about picking a cup size — it is about matching the implant's dimensions to your unique body proportions. This guide explains the key factors.

Why cup size is not a reliable measurement

Cup sizes vary dramatically between brands and countries. A "C cup" in one bra brand can be a "D cup" in another. Implant size is measured in cubic centimetres (cc), which is a precise, universal measurement. Dr. Erdal uses anatomical measurements — not cup size targets — to determine the optimal implant volume for each patient.

Implant volume (cc) — what the numbers mean

Implant volumes typically range from 125 cc to 800 cc. For most patients, the final selection falls between 250 cc and 450 cc. Here is a general guide:

Volume RangeTypical Result
150–250 ccSubtle, natural enhancement — roughly 1 cup size increase
250–350 ccModerate enhancement — approximately 1–2 cup sizes
350–450 ccNoticeable enhancement — approximately 2–3 cup sizes
450–550 ccSignificant enhancement — 3+ cup sizes
550+ ccDramatic enhancement — requires adequate tissue

Key point: The same implant volume looks completely different on different body frames. A 350 cc implant on a petite patient with a narrow chest will look much larger than on a patient with a broader frame. This is why anatomical measurements matter more than cc alone.

Implant profile — what is it and why it matters

Profile refers to how far the implant projects forward from the chest wall. For the same volume, a higher profile implant has a narrower base but more projection. Available profiles include:

Round vs. anatomical (teardrop) implants

Round implants distribute volume evenly and provide fullness in the upper pole of the breast. When standing upright, they may take on a slightly teardrop-like appearance due to gravity.

Anatomical (teardrop) implants, also called gummy bear implants, have more volume in the lower pole and less in the upper pole, mimicking the natural breast shape. They are typically textured to prevent rotation.

Surface texture options

Silicone vs. saline fill

Silicone gel is the most popular fill worldwide. Cohesive silicone gel maintains shape, feels natural and closely mimics breast tissue. Saline is sterile saltwater, filled after insertion — allowing a smaller incision. Both are safe and well-established options.

How Dr. Erdal selects your implant

During your consultation, Dr. Erdal takes precise measurements of your chest width, breast base diameter, tissue thickness and skin elasticity. These measurements, combined with your aesthetic goals, determine the recommended implant volume, profile and shape. You also have the freedom to choose your preferred implant brand — at no additional cost.
