How to Choose the Right Breast Implant Size
Implant size is measured in cubic centimetres (cc), not cup sizes — and is determined by chest width, tissue thickness, and body proportions. Typical range: 200–500cc; most natural results: 275–375cc. Profile (low / moderate / moderate-plus / high / extra-high) affects projection for the same base width.
Implant size is measured in cubic centimetres (cc), not cup sizes. Selection is based on chest width, tissue thickness, and desired projection — not on a target cup size. Most breast augmentation patients receive 250–400cc implants, with 300–350cc being most common for natural results. Implant profile (low, moderate, high, extra-high) determines projection-to-base-width ratio. Dr. Erdal selects size based on precise anatomical measurements during consultation; sizing alone in the consultation room (with sizers under a sports bra) refines the final choice.
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 Range | Typical Result |
|---|---|
| 150–250 cc | Subtle, natural enhancement — roughly 1 cup size increase |
| 250–350 cc | Moderate enhancement — approximately 1–2 cup sizes |
| 350–450 cc | Noticeable enhancement — approximately 2–3 cup sizes |
| 450–550 cc | Significant enhancement — 3+ cup sizes |
| 550+ cc | Dramatic 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:
- Low profile — wider base, minimal projection. Suits broad-chested patients wanting a subtle result.
- Moderate profile — balanced width and projection. A versatile middle ground.
- Moderate-plus profile — slightly more projection than moderate. Very commonly selected.
- High profile — narrower base with significant projection. Ideal for narrow-chested patients or those wanting a more prominent result.
- Extra-high profile — maximum projection from the narrowest base. Selected for specific anatomical situations.
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
- Smooth — soft, free to move naturally within the pocket
- Microtextured — a gentle surface for moderate tissue integration
- Textured — designed to adhere to surrounding tissue, reducing movement
- Polyurethane-coated — strong tissue integration, lowest capsular contracture rates
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.

There is no universal 'right size' — it depends on chest width, tissue thickness, body proportions, and aesthetic goals. Most patients receive 250–400cc implants. Smaller frames typically need narrower-base, higher-profile implants; broader frames need wider-base implants. The selection is made through precise anatomical measurement during consultation, supplemented by physical sizing with implant sizers in a sports bra to confirm visual outcome.
Approximately 150–200cc equals one cup size, but this varies significantly with chest width and tissue distribution. A 350cc implant on a smaller frame produces more visible cup-size change than the same implant on a broader frame. Cup size is an unreliable target for surgical planning; cubic-centimetre volume on appropriate base width is the precise measurement.
Implant profile describes how far the implant projects forward from the chest wall relative to its base width. Low profile (widest base, minimal projection) suits broader chests. Moderate (balanced — most common) suits average chest widths. High (narrow base, strong projection) suits narrower chests. Extra-high (narrowest base, maximum projection) is reserved for petite or very narrow frames. The right profile is determined by chest width measurement, not personal preference alone.
Yes — implant sizers (silicone-filled forms) can be tried on under a sports bra during consultation to give a visual approximation. This is more reliable than computer simulations for natural perception. Final selection combines precise anatomical measurements (objective) with sizer trial (subjective) to produce a balanced choice.
