Cup Size Equivalent of 340cc Silicone High Profile Breast Implants?

I am getting Allergan 340cc Silicone Breast implants (High Profile) in a few weeks. I wanted to know if that is a D cup or a Full C?

Also what would be a good size for me? I am 5'10" 140lbs nice tight and toned frame but looking for nice fullness up top.

Implant Sizing

Very difficult to say. Implant sizing is not something that can be determined just by your height and weight. You need to be measured around your chest and we need to know what size breast you have know and the number. It would also help to have a picture. What may be a C cup for you may be a B cup for another and a DD for someone else.
Good luck.

Cup size from breast implants depends on your frame and measurements


Choosing the right size breast implant for a particular patient takes experience and an examination. Two women will carry the same implant differently. 340 cc is a moderate size in most women and will give a cup to a cup and a half cup enlargement on average. Maybe go over this with your surgeon before making your choice.

Implant and cup size

Choosing the right implant for you is determined after a thorough physical exam and long discussion about your goals.  The volume does not always match up with the cup size.

Breast implants measured by CC's not cup sizes.

It is very easy to be confused by this measuring system. Cup sizes are only used as estimates for clothing. Although the measuring technique for determining cup size is precise, the results of these measurements are not. Let me give you an example; weight is a very accurate measurement. However two patients that weigh 120 lbs are not likely to look alike. The same is true with two patients that have C cup breasts. This is why physicians tend to use volume (cubic centimeters or cc) as a more accurate measurement. Note: If you are trying to figure out what breast implant size you want to obtain, you can try the sizing tool available through or read the articles about measuring there.
Size is a complex decision that is not only based upon your height, weight and current cup/bra size but ALSO on also on your breast diameter, waist, shoulder, and skin envelope measurements. These can only be assessed in person during a consultation. A good place to start is using my "Find your perfect size" tool listed in the left hand column of my home page. Another good place to look is the searchable database section of the physicians' photos on Best of luck.
