How to Choose Breast Implant Size Realistically

Many people start with a cup size in mind, but cup sizes vary between brands and countries. Implants are measured in cubic centimetres (cc), and the same volume looks different on different bodies.

What influences the right size

• Chest width and breast base width
• Existing breast volume and shape
• Skin elasticity and the soft tissue available to cover the implant
• Body proportions and height
• Your goals and lifestyle, including exercise

Why bigger is not always better

Larger implants place more stretch and weight on tissues. They can increase the chance of visible rippling, thinning of tissue, sagging over time and further surgery. A size that looks good in a photograph may not suit your tissue.

Tools that help

Surgeons may use sizers placed inside a bra, measurements of the breast base and 3D simulations. Treat simulations as a rough guide only, because they cannot predict how your tissues will heal and settle.

How to communicate your goals

• Use photos to show the look you want, not just a size
• Bring pictures of results you do not want
• Ask the surgeon to explain which of your wishes your anatomy supports

Settling

Swelling means that the size you see in the first weeks is not the final result. Implants also settle over time. Ask when your surgeon expects the result to stabilise and what changes are normal.
