Breast Implant Size vs. Cup Size 

Patients often begin the breast enhancement process with ideas about the cup size they want to achieve. While this can give your surgeon a rough idea of your aesthetic goals, implants don’t measure the same as bra cups do. Breast implants come in varying volumes, measured in cubic centimeters (cc). A smaller implant may range between 100 and 250 cc, while larger implants may measure 400 cc or more. 

This general size guide will help you understand how breast implant sizing works: 

• Small Implants: 100–250 cc
• Medium Implants: 250–400 cc
• Large Implants: 400+ cc  

Most patients find that every 150-200 cc of breast implant volume will give them an increase of one cup size. However, this may vary slightly from patient to patient. Your plastic surgeon will help you determine the best implant size based on your body shape, chest width, and desired results. 

Breast Implant Profiles: Choosing Your Projection

Cubic volume is just the start of choosing your breast implant size. Implants also vary in their profile (projection), which can significantly alter your breast enhancement results. Profile options include: 

• Low Profile: Offers minimal projection, tends to work best on wider chests
• Moderate Profile: Produces natural projection that works well for smaller chests 
• High Profile: Features maximum projection for the narrowest chests 

Low-profile implants focus on projecting the central part of your breast forward for a flatter shape. High-profile implants project the central and lower parts of the breast, giving you a prominent, round breast shape and maximizing cleavage. 

Why Bigger Isn’t Always Better 

Women often assume they want bigger implants to achieve the most prominent curves and dramatic results. However, when it comes to breast augmentation, bigger isn’t always better. In fact, implants that are too large can negatively impact your life in these ways: 

• Impedes your physical activities, particularly running and other forms of exercise
• Causes the breasts to sag, resulting in the need for a surgical breast lift 
• Results in strain on your neck and back, leading to chronic pain 

For women with a petite body shape or a narrow chest, smaller implants may yield the most natural results. While the choice of breast implant size is highly personal, your surgeon will guide you through the process to ensure you achieve an outcome that makes you comfortable and confident in your new look. 

Factors to Help You Choose Your Breast Implant Size 

Breast implant size is based on the needs and goals of each patient, but there are a few factors to consider as you are contemplating the best size of breast implants: 

• Implant Shape: Teardrop-shaped implants feature less upper pole fullness and may offer a more natural appearance for women with less breast tissue. Round implants tend to produce significant upper pole fullness and cleavage. 
• Body Shape: Variables such as your height, chest width, and bone structure may affect how your implants appear. Smaller women may look more proportionate with smaller, higher-profile implants, while taller women may prefer lower-profile implants with wider diameters.  
• Lifestyle: Larger implants may make sports and exercise more challenging. Smaller implants or a lower profile could give you the additional curves you want without impeding your activities. 
• Wardrobe Choices: One goal of breast enlargement is to make clothing fit more attractively. Low-cut tops may look better with a higher profile implant that creates more defined cleavage.
• Future Family Plans: Consider how your implants could affect future pregnancies and breastfeeding. While women with implants can breastfeed, smaller implants are less likely to impact the milk ducts.
