Your Guide to the 2026 Mentor Implant Sizes Chart

A detailed Mentor implant sizes chart is one of the most important tools we use to begin a conversation about breast augmentation. It’s essentially a catalog that connects an implant’s volume, measured in cubic centimeters (CCs), to its actual physical dimensions—things like its width and how far it projects from the chest. This chart helps translate abstract numbers into a tangible understanding of shape and proportion.

Quick Reference for Mentor Implant Sizes

While the full Mentor implant sizes chart can feel overwhelming with its hundreds of options, a quick reference guide is a great way to get oriented. The table below is a simplified snapshot, designed to give you an at-a-glance look at how common implant volumes correspond with different profiles and their resulting dimensions.

Think of this as a "cheat sheet" to help you start visualizing the possibilities before we dive into the specifics during your consultation.

Understanding the Key Metrics

Before you look at the numbers, it helps to know what they mean and, more importantly, how they work together. Each measurement plays a critical role in shaping the final outcome.

• Implant Volume (CC): This is the amount of silicone gel inside the implant. While it's the number most people focus on, it's only one piece of the puzzle. A 400 CC implant, for example, can look dramatically different from one person to the next.
• Available Profiles: An implant’s profile determines how much it "projects" forward. Mentor offers a range including Moderate, Moderate Plus, High, and Ultra High. A higher profile means more forward projection on a narrower base.
• Typical Base Diameter (cm): This is the width of the implant at its base. The goal is to match this measurement to the natural width of your own breast tissue (your "breast footprint") for a seamless, natural-looking fit.
• Typical Projection (cm): This measurement tells you exactly how far the implant will extend from the chest wall at its center. This is what creates the "fullness" you see from the side.

Looking at these dimensions together shows you that size is about so much more than just a CC number. The following table provides a high-level summary to help you see these relationships in action.

Mentor Implant Volume and Dimension Overview

This table provides a general overview of how implant volume (CCs) corresponds to available profiles and the typical ranges for base diameter and projection.

Remember, this is a starting point. The perfect implant for you is a unique combination of these metrics, all selected to harmonize with your specific anatomy and aesthetic goals.

How to Read a Mentor Implant Sizes Chart

A professional Mentor implant sizes chart can look pretty intimidating at first glance—it's a lot more than just a simple list of sizes. Think of it as a blueprint that you and your surgeon will use to map out your final look. To really get the most out of your consultation, you need to understand the three core measurements that define every implant: volume, base diameter, and projection.

Getting a handle on these numbers is what turns a potentially confusing conversation into a productive planning session. It empowers you to describe exactly what you're hoping for and helps ensure you and Dr. Fater are on the same page from the start.

The Core Measurements That Define an Implant

Every single Mentor implant is described by three key dimensions that all work together. A common mistake patients make is focusing only on one of these, like volume, which can lead to results that don't quite match their goals.

• Volume (CCs): This is the total amount of MemoryGel™ the implant holds, measured in cubic centimeters. While it's the main indicator of overall size, it's not the whole story. Two implants can have the exact same volume but completely different shapes.

• Base Diameter (cm): This is the width of the implant where it rests against the chest. Frankly, this is the most important number of the three. For a natural-looking result, the implant's base diameter needs to align with the width of your own breast tissue.

• Projection (cm): This is how far the implant "projects" forward from your chest wall. It's the dimension that creates fullness and defines your profile. A higher projection gives you a more prominent, rounder curve.

A good way to think about it is like buying tires for your car. The volume is like the total amount of rubber, but the diameter has to fit the wheel, and the tire's width (its projection) has to fit in the wheel well without rubbing. All three measurements have to be right for a perfect fit.

Putting It All Together: A Practical Example

Let’s look at a real-world scenario to see how these numbers play out. Imagine a patient is trying to decide between two different 350cc Mentor implants.

Example A: A 350cc Moderate Plus Profile implant might have a base diameter of 12.5 cm and a projection of 4.1 cm. This combination creates a wider, more gently sloped look.

Example B: In contrast, a 350cc High Profile implant could have a narrower base of 11.5 cm but a greater projection of 4.7 cm. This one would deliver more forward fullness on a smaller "footprint."

Even though both implants are 350cc, the final breast shape they create will be completely different. This is precisely why the Mentor implant sizes chart is such an indispensable tool. It allows Dr. Fater to first select an implant with a base diameter that fits your frame perfectly, then fine-tune the projection to achieve the specific aesthetic you desire—whether it's a subtle, natural enhancement or a more dramatic curve.

Choosing Your Ideal Implant Profile

While the number of CCs (cubic centimeters) tends to grab all the headlines, your implant’s profile is just as crucial in defining your final look. The profile is simply a measure of how far the implant projects forward from your chest.

Think of it this way: two implants can have the exact same volume, but one can be wide and flat like a pancake, while the other is narrow and projects forward like a cone. They hold the same amount of gel, but the shape they create is worlds apart. Understanding this difference is key to translating the numbers on a Mentor implant sizes chart into your real-world aesthetic goals.

Breaking Down Mentor Implant Profiles

Mentor’s MemoryGel™ and MemoryGel® Xtra implants come in four distinct profile options. Each one offers a different balance between the implant's base width and its forward projection, allowing for a truly customized fit.

• Moderate Profile: This is our widest, flattest option. It has the most gradual slope and is a great choice for patients with a broader chest who are looking for a subtle, natural-looking volume increase that blends seamlessly with their frame.

• Moderate Plus Profile: Easily one of the most popular choices, the Moderate Plus is the perfect "in-between." It offers a bit more projection than the Moderate profile but on a slightly narrower base, creating a beautiful balance of fullness without being overly dramatic.

• High Profile: With a noticeably narrower base and more forward projection, the High Profile creates a rounder, more prominent breast shape. This is often the go-to for women with a petite or narrow frame who want significant volume and "upper pole" fullness without the implant feeling too wide.

• Ultra High Profile: As the name suggests, this profile provides the maximum possible projection on the narrowest base. It’s designed for patients who want the most dramatic, projected result with a lot of cleavage and a very round, full appearance.

The main takeaway here is that for the same volume—let's say 400cc—an Ultra High Profile implant will look much more projected and feel narrower on the chest than a Moderate Profile implant, which will be wider and sit flatter.

How Profile Choice Affects Your Look

The profile you and your surgeon select has a direct and powerful impact on your final silhouette. For instance, putting a High Profile implant on someone with a very broad chest can sometimes create a "stuck-on" appearance because it doesn't adequately fill out their natural breast width.

On the flip side, using a low-profile implant on a very petite woman might not provide enough forward "oomph" to achieve the look she was hoping for, even if the CC volume is right. A patient with a naturally wide breast base is often a fantastic candidate for a Moderate Plus implant, which fills out her frame perfectly while adding a pleasing projection. Someone else with an athletic, narrow torso might opt for an Ultra High Profile to get that classic curvy look without the implant's edges spilling into her armpit area.

This is exactly why the detailed measurements in a Mentor implant sizes chart are so critical. By looking at the base diameter, projection, and volume together, Dr. Fater can pinpoint the implant that not only matches your desired size but also perfectly fits your unique body. In the sections that follow, you’ll find the complete data tables that show you these precise differences side-by-side.

The Complete Mentor MemoryGel Implant Size Tables

Alright, let's get into the specifics. This is where we look at the exact numbers that surgeons use to plan a breast augmentation. The following tables lay out the official specifications for the Mentor implant sizes chart, turning abstract terms like "profile" and "volume" into concrete measurements.

Think of this as your cheat sheet. By organizing the data by implant profile, you can easily compare different options. For instance, you can see precisely how a 400cc Moderate Plus implant differs in its base width and forward projection from a 400cc High Profile implant. Having a grasp of these details helps you and your surgeon have a much more focused conversation about achieving your aesthetic goals.

Mentor MemoryGel Moderate Plus Profile Implant Specifications

The Moderate Plus profile is a true classic in our practice, and for good reason. It offers a beautiful balance, providing noticeable volume without looking unnatural. This profile is often a perfect fit for patients with an average or slightly wider chest who want a significant but still proportionate enhancement.

As you'll see in the data, when the implant volume (cc) increases, both the base diameter and the projection grow in a balanced way. Mentor has been refining these dimensions since its founding in 1969, and its MemoryGel™ implants are a trusted choice here at Cape Cod Plastic Surgery. The range is impressive; a tiny 125 cc Smooth Round Moderate Plus implant measures 8.9 cm across with a 2.8 cm projection, while the largest 800 cc version expands to 17.2 cm wide with a 4.6 cm projection. To see every single option, you can look through the full Mentor implant catalogue sizer.

Here’s a quick look at some of the most commonly selected sizes within this versatile profile.

These specifications give us the precise building blocks to customize your results based on your unique anatomy.

MemoryGel Xtra High Profile Implants

The MemoryGel® Xtra line is a different beast altogether. Mentor engineered these implants to feel a bit firmer and provide more upper-pole fullness. When you pair that "Xtra" technology with a High Profile, the result is an implant designed for maximum forward projection on a relatively narrow base.

This creates a very round, prominent breast shape. It's an excellent choice for patients who:

• Have a more narrow or petite frame.
• Desire a more dramatic, "augmented" look.
• Want significant projection without the implant feeling too wide on the chest.

So, what exactly does "Xtra" mean? It means the implant shell is filled more completely with the cohesive gel. This is what gives it that enhanced firmness and a noticeable boost in projection compared to a standard MemoryGel™ implant of the exact same size and profile.

The table below shows some popular Xtra High Profile sizes. Notice how much projection you get relative to the diameter—that's the signature of this implant style.

Of course, looking at numbers on a screen is just the first step. To get a better sense of how these measurements translate to real-world results and different body types, be sure to read through our complete breast implant size guide.

Why CCs Do Not Equal Cup Size

One of the first questions patients often ask is, "How many CCs will get me to a D cup?" It's a totally understandable question, but the truth is, there’s no magic number. A 350cc implant might look like a C cup on one person and a D cup on another. It's just not that simple.

Your final cup size is a combination of the implant's volume and your own unique anatomy—your existing breast tissue, the dimensions of your chest, and even your skin's elasticity. Think of it this way: pouring a cup of water into a tall, thin flute glass creates a very different result than pouring that same cup of water into a short, wide tumbler. Your body is the unique "glass" that gives the implant its final shape and size.

Factors That Influence Your Final Size

Focusing only on CCs means you're missing the bigger picture, which is finding a size and shape that looks beautiful and harmonious on your body. This is where a surgeon's experience really comes into play.

Here are the key factors we evaluate to predict your outcome:

• Existing Breast Tissue: This is your starting point. A patient who already has a fair amount of natural breast volume will naturally end up with a larger final cup size than someone starting with very little tissue, even with the exact same implant.
• Chest Wall Dimensions: The width and shape of your ribcage are your body's foundation. A wider chest can accommodate a wider implant, which tends to spread the volume out, creating a different look than a narrower implant on a petite frame.
• Skin Elasticity: We also have to consider how well your skin can stretch to house the new volume. Tighter skin might constrain an implant slightly, while skin with more give allows the implant to expand to its full, projected shape.
• Implant Profile: As you'll see in the charts, profile is just as important as volume. A 350cc High Profile implant projects forward significantly more than a 350cc Moderate Profile implant, and that difference in projection will dramatically affect your silhouette and bra size.

This is why we rely on detailed specifications, not just a single volume number.

The three core measurements—volume, diameter, and projection—all work together. Understanding how they're connected is why a full Mentor implant sizes chart is an indispensable tool for surgical planning.

Shifting Focus From Cup Size to Proportion

While having a goal cup size is a great place to start the conversation, our mission at Cape Cod Plastic Surgery is to create a beautiful shape and proportion that truly fits your body. During your consultation, we'll spend less time talking about a letter on a bra tag and more time focused on the silhouette you want to see in the mirror.

The most successful and satisfying outcomes happen when patients shift their goal from hitting a specific letter to achieving a specific look. We prioritize proportion, shape, and a natural fit over an arbitrary cup size.

This philosophy is precisely why the in-office fitting process is so critical. Using implant sizers, we can help you physically see and feel how different dimensions will look and feel on your frame. It’s a hands-on, collaborative process that moves the conversation beyond the limits of CCs and cup sizes, making sure your final result is something you'll absolutely love.

Your Personalized Fitting with Dr. Fater

Familiarizing yourself with a Mentor implant sizes chart is a great first step, but it's only half the story. The numbers and measurements on a page can't tell you how an implant will actually look and feel on your body. This is where the consultation and personalized fitting come in—it’s where the technical data meets the art of aesthetic surgery.

During your fitting, abstract numbers become a real, tangible preview of your final results. It's a collaborative experience designed to ensure you feel completely confident in your decisions.

The Fitting Process Step by Step

Dr. Fater’s fitting process is meticulous, combining time-tested techniques with modern technology to help you clearly visualize the outcome. He leaves no stone unturned to make sure every choice is right for you.

Here’s a look at what you can expect during your appointment:

Frequently Asked Questions About Mentor Implant Sizes

Even after looking over a detailed Mentor implant sizes chart, it’s completely normal to have more questions. We get it. Let’s dive into some of the most common ones we hear from our patients, clearing up the practical details so you can feel confident heading into your consultation.

These are the kinds of questions that pop up once you start picturing how the numbers and profiles will actually translate to your body.

What Is the Most Popular Mentor Implant Size?

We see a lot of patients choosing implants in the 300cc to 500cc range, but honestly, the whole idea of a "popular" size is a bit of a trap. When it comes to breast augmentation, the best size is simply the one that fits your body's proportions perfectly.

The single most important factor isn't a cc number that’s trending online; it's the implant's base diameter. Dr. Fater’s first priority is to match that width to your unique chest dimensions. This ensures your final result looks like it belongs to you—balanced and natural, not just a size someone else chose.

How Do I Know Which Implant Profile Is Right for Me?

Your ideal profile really comes down to a combination of your body frame and the look you're hoping to achieve. This is where we balance the implant's width with how much it projects forward.

• Moderate Profiles have a wider base and a gentler, sloping appearance. They're a fantastic choice for women with a broader chest who want a subtle, very natural-looking enhancement.
• High and Ultra High Profiles, on the other hand, give you more forward projection on a narrower base. These are often the go-to for women with more petite frames who are looking for a rounder, fuller shape, especially in the upper part of the breast.

This is something you can't decide from a chart alone. During your fitting, Dr. Fater will have you try on sizers to physically show you how each profile looks and feels on your body, taking all the guesswork out of the decision.

Do Larger CC Implants Increase Health Risks?

The main health consideration isn't the implant's cc volume itself, but whether the implant is inappropriately large for your frame. An implant that's too wide or heavy for your body's tissues to support can raise the risk of long-term problems.

Some potential complications from a poorly-sized implant include "bottoming out" (where the implant sags below the breast fold), visible rippling, or just chronic strain on your skin and tissue. This is exactly why getting a professional assessment is non-negotiable for a safe, beautiful outcome.

Dr. Fater will only ever recommend implant sizes that your body can safely support for the long haul. The goal is a result that not only looks incredible but also prioritizes your health and comfort for years to come.
